Deploy production REST and Neo4j Graph APIs from JSON schemas in seconds.
RationalBloks lets an assistant create, deploy and manage production REST and Neo4j graph APIs from JSON schemas, plus modules and graph data.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.rationalbloks%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Deploy production APIs in minutes. Tools for projects, schemas, deployments, modules, object storage, and graph data — delivered on infrastructure you own (self-host or your own BYOC cluster).
RationalBloks MCP lets AI agents (Claude Code, Claude Desktop, Cursor, VS Code, etc.) deploy production APIs from a JSON schema, and deploy and run the frontends and backends built on them. No backend code to write. No infrastructure to manage.
Visit rationalbloks.com/settings and create an API key. A key carries scopes: a read key reaches only the read tools, a read + write key reaches every tool. The server lists only the tools your key may call.
Claude Code — remote server (no install):
or the local server:
--scope project writes the server to the repository's .mcp.json instead, to share it with a team. Keep the key out of the file with "Authorization": "Bearer ${RATIONALBLOKS_API_KEY}": Claude Code expands the variable from each developer's environment.
VS Code — add to .vscode/mcp.json (Cursor: .cursor/mcp.json with a mcpServers key):
Claude Desktop — add to claude_desktop_config.json:
Any other client: point it at https://mcp.rationalbloks.com/mcp (Streamable HTTP) with Authorization: Bearer rb_sk_....
Every tool that can lose data carries destructiveHint: true, and no other tool can lose data. One allow rule covers the server, and ask rules keep a prompt on the tools that can lose data. Claude Code evaluates ask rules before allow rules, so they prompt even though the server is allowed, and in auto mode they still prompt, because they run before the classifier. Add this to .claude/settings.json (the project) or ~/.claude/settings.json (every project):
Add "mcp__rationalbloks__deploy_production" to ask to approve each production release yourself.
Asked before every change: allow only the read tools instead. These rules match every read tool and no other:
Read-only server: register a second server with a read key. It lists only the read tools and the platform refuses every other call, so one rule allows all of it:
Auto mode reads autoMode only from ~/.claude/settings.json, managed settings or --settings, never from a project's .claude/settings.json. If its classifier blocks routine RationalBloks calls, describe your project there, keeping $defaults (replace MyProject and apps.yourdomain.com with your project's name and your cluster's domain):
Run claude auto-mode config to see the rules in effect, or edit them in /permissions (Auto mode tab).
Read tools only read. Write tools change something, and never lose data. Destructive tools can lose data, and carry destructiveHint: true: they replace a whole schema (update_schema, update_graph_schema), drop, delete, roll back, deploy a plan that drops data (deploy_destructive), or overwrite a module's environment (set_module_env).
A plan drops data when it drops a table or field, or changes a field's type in a way that rounds or cuts its stored values (a decimal given a smaller scale or turned integer, a datetime turned date). The deploy tools refuse such a plan and name each drop; deploy_destructive applies it.
A long operation (create, deploy, rollback, delete, module operations) runs as a job: the tool answers a job_id, and get_job_status follows it to its result.
A module is one of a project's own frontends (frontblok) or backends (logicblok), built from a GitHub repository and run beside the project.
Schemas must be in FLAT format:
These are automatic - don't define them:
id (UUID primary key)created_at (datetime)updated_at (datetime)row_version (integer: the row's version, 1 on insert and one more on every update)Use the built-in app_users table:
get_schema_reference covers the advanced features: row policies, computed fields, unique groups (nulls_not_distinct for groups with nullable columns, deferrable for groups checked at commit), audit trails, the generated API's scoped deletes, and writes that state the row_version they read (If-Match, if_version).
For frontend development, use our NPM packages:
These provide:
getApi().getAll(), getApi().create(), etc.Proprietary - Copyright 2026 RationalBloks. All Rights Reserved.

Takes no parameters.
Get Project Details
Get detailed information about a specific project
project_idrequiredGet Project Schema
Get the JSON schema definition of a project in FLAT format. Returns the schema structure where each table name maps directly to field definitions. This is the same format required for create_project and update_schema. USE CASES: Review current schema before making updates, copy schema as template for new projects, verify schema structure after deployment, learn the correct schema format by example. The returned schema will be in FLAT format: {table_name: {field_name: {type, properties}}}. The response also says whether this saved schema is the deployed one: saved_schema_deployed is true when the last deploy applied it, false when it was saved after the last deploy (undeployed_changes then lists what deploying it would change), and null when no deployed schema is on record. A LARGE SCHEMA: pass tables or fields to read only the part you are about to change — the answer's 'version' is the whole schema's either way, so a slice is enough to patch it with patch_schema(expected_version=...).
fieldstablesproject_idrequiredGet User Info
Get information about the authenticated user
Takes no parameters.
List Resource Pools
List your registered BYOC resource pools (client-owned Kubernetes clusters). Each returned cluster has an 'id' you MUST pass as create_project's cluster_id to deploy a project onto your own infrastructure — owned hosting is retired, so every project we operate runs on your own cluster. Registering a pool is a UI action (create a bare Ubuntu box, authorise the key we generate, then we provision it into a cluster automatically) — this tool only lists pools you already registered, it never handles cluster credentials.
Takes no parameters.
Get Job Status
Check the status of a job (a create, deploy, promotion, rollback, deletion or module operation). STATUS VALUES: pending (queued), processing (in progress), completed (success), failed. Call it until the status is completed or failed: every job ends, since a job whose server stopped is failed within about three minutes, and a deploy can take up to 15 minutes. A module job names its module_code, and a completed module build's result names the image it built (its commit). If status is 'failed', read failure_side and error: 'customer' means the project's input is proven the cause (an invalid schema, data the new schema does not fit, a change the resource pool cannot hold), and error says what to change; 'platform' means no input of the project is known to cause it: report it to RationalBloks rather than changing the schema.
job_idrequiredList Project Jobs
List a project's jobs, newest first: every create, deploy, promotion, rollback, resource change and module operation, each with its status, error, failure_side and when it started and ended. A job's record is kept for the life of the project, so this is how to find out what an operation did when you no longer have its job_id (after an interruption, or in a later session): the first job of the job_type you want is the latest. Read older jobs a page at a time with offset; a page shorter than limit is the last.
limitoffsetproject_idrequiredGet Project Info
Get detailed project info including deployment status and resource usage. DEPLOYMENT STATUS: Running (healthy), Pending (starting), CrashLoopBackOff (init container failed - usually schema format error), ImagePullBackOff (image build failed). TROUBLESHOOTING: If status is CrashLoopBackOff, the schema is likely in wrong format (nested 'fields' key or missing 'type' properties). Use get_schema to review current schema. If replicas show 0/2, the init container (migration runner) is failing. This is almost always a schema format issue. RETURNS THE LIVE API URL: staging.url and production.url carry the deployed base URL for each environment (append /docs for the interactive OpenAPI docs); github.url is the generated repository. create_project does NOT return a URL, so this is the tool to call once get_job_status reports the deployment finished.
project_idrequiredGet Version History
Get the deployment and version history (git commits) for a project. Shows all schema changes with commit SHA, timestamp, and message. USE CASES: Review what changed between deployments, find the last working version before issues started, get commit SHA for rollback_project.
project_idrequiredGet Template Schemas
Get pre-built template schemas for common use cases. ⭐ USE THIS FIRST when creating a new project! Templates show the CORRECT schema format with: proper FLAT structure (no 'fields' nesting), every field has a 'type' property, foreign key relationships configured correctly, best practices for field naming and types. Available templates: Start from Scratch (every field type), Team Collaboration (workspaces, channels, messages, tasks), E-Commerce Store (customer profiles, products, orders and their line items, reviews, shipments). Each entry's 'schema' goes to create_project as is or adapted; its 'tables' notes say how each table is authorized. TIP: Study these templates to understand the correct schema format before creating custom schemas.
Takes no parameters.
Get Schema Features Reference
Get the reference for ADVANCED schema features the templates do not show — read this before adding authorization or derived fields to a schema. Covers: __policy__ (relationship-based read/write authorization with single- and multi-hop membership paths, and the rules that decide whether adopting it is safe — it replaces creator-ownership per table and fails closed on a null link), computed columns (read-only values derived from other columns), __constraints__ (composite uniqueness, checked at commit when deferrable), __audit__ (append-only audit log), __admin_write__ (a table only admins write), how user foreign keys are attributed on create, reading many rows in one request with <field>__in=a,b,c (the values separated by commas only), deleting the rows a filter names with expected_count, and writes that state the row_version they read (If-Match on a route, if_version in a batch).
Takes no parameters.

Takes no parameters.
Get Project Usage
Get resource usage metrics (CPU, memory) for a project
project_idrequiredGet Project Storage Usage
Get object-storage usage for a project: file count and bytes used against the plan limits.

versionrequiredproject_idrequiredPreview Schema Change
Preview a schema change, saving nothing: the one way to see what a change would do before it is saved. Pass ONE of: • operations: the operations patch_schema or drop_schema_items would apply (relational projects) • schema: a whole schema in place of the saved one (relational or graph projects) ANSWER: 'applied' (for operations), 'diff' (every property saving it would change, by path), 'summary' and 'plan' (the migration the next deploy would then run, every table, field, entity or relationship it drops named), and 'version' (the saved schema's: pass it as expected_version to the save that follows, so it is refused if someone saved meanwhile). A relational schema the deploy would refuse is refused here, with the reason.
schemaoperationsproject_idrequiredCreate Project
Create a new RationalBloks project (a PostgreSQL REST API) from a JSON schema, on one of your resource pools. ⚠️ CRITICAL RULES - READ BEFORE CREATING SCHEMA: 1. FLAT FORMAT (REQUIRED): ✅ CORRECT: {"orders": {"total": {"type": "decimal", "precision": 10, "scale": 2}}} ❌ WRONG: {"orders": {"fields": {...}}} — never nest under 'fields' 2. EVERY field has a "type": string (MUST have max_length), text, integer, decimal (precision, scale), boolean, uuid, date, datetime (NOT "timestamp"), json, and the PostgreSQL arrays uuid_array, integer_array, text_array, float_array (GIN-indexed: @> contains, <@ contained_by, && overlaps) 3. AUTOMATIC FIELDS (DON'T define): id, created_at, updated_at, row_version 4. USERS: NEVER create users/customers/employees tables with email or password. Link to the built-in app_users table: {"user_id": {"type": "uuid", "foreign_key": "app_users.id"}}. A table with such a field is owner-scoped: each user sees their own rows. 5. FIELD OPTIONS: required, unique, default, enum, foreign_key ("table.id"), on_delete (cascade, set_null, restrict, no_action), nullable, index, description, write_only, computed. Advanced features (__policy__, computed columns, __constraints__, __audit__): get_schema_reference. BACKEND ENGINE (backend_type): "python" (FastAPI, default) or "rust" (Axum: faster cold starts, lower memory). WORKFLOW: 1. get_template_schemas FIRST to see valid examples 2. create_project with a cluster_id from list_clusters 3. Poll get_job_status with the returned job_id (2-5 minutes) 4. get_project_info gives the live URL While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
namerequiredschemarequiredcluster_idrequiredbackend_typeUpdate Schema
Replace a project's WHOLE schema (saves to database, does NOT deploy). DESTRUCTIVE: a table or field the schema leaves out is dropped by the next deploy. For a new data model or a template. To change part of a schema use patch_schema, and drop_schema_items to drop; sending back a large schema to change one field risks changing something else on the way. ⚠️ Follow ALL rules from create_project: • FLAT format (no 'fields' nesting) • string: max_length (default 255) • decimal: precision + scale (default 10, 2) • Use "datetime" NOT "timestamp" • DON'T define: id, created_at, updated_at, row_version • NEVER create users/customers/employees tables (use app_users) ⚠️ MIGRATION RULES: • New fields MUST be "required": false OR have "default" value • Cannot add required field without default to existing tables WORKFLOW: 1. get_schema to see the current schema (its 'version' pins the save) 2. preview_schema_change with the new schema: check 'diff' and 'plan' 3. update_schema (pass expected_version to be refused if someone else saved meanwhile) 4. deploy_staging, then get_job_status A schema the deploy would refuse is refused here, and nothing is saved. The answer carries 'diff', 'plan' and the new 'version'.
schemarequiredproject_idrequiredexpected_versionPatch Schema
Change PART of a project's schema without dropping any of it (saves to database, does NOT deploy). Send only the change. The server applies it to the saved schema, in order and all together, and keeps every table and field it does not touch — including their identity, so a rename stays a rename and the column keeps its data. OPERATIONS (each one small object, applied in the order given): • {"op": "add_table", "table": "clocks", "definition": {...}} new table, same FLAT rules as create_project • {"op": "rename_table", "table": "clocks", "to": "timers"} • {"op": "add_field", "table": "assets", "field": "serial", "definition": {"type": "string", "max_length": 64}} • {"op": "rename_field", "table": "parameters", "field": "is_clock", "to": "clock_kind"} • {"op": "set_field", "table": "assets", "field": "name", "properties": {"max_length": 300}} merges; a property set to null is removed • {"op": "set_table", "table": "assets", "properties": {"__audit__": true}} __policy__, __constraints__, __audit__, __admin_write__ Dropping a table or field is drop_schema_items, a tool of its own. ALL OR NOTHING: an operation that cannot be applied — a table or field that is not there, a name already taken, a schema the deploy would refuse — refuses the whole patch, naming the operation, and nothing is saved. EVERY ANSWER IS A DIFF: 'applied' (what each operation did), 'diff' (every changed property by path), 'summary' and 'plan' (the migration a deploy would then run), and 'version' (the schema's version after the change). WORKFLOW: 1. get_schema with tables/fields to read the part you are changing (its 'version' is the whole schema's) 2. preview_schema_change with the operations: check 'diff' and 'plan' 3. patch_schema with the same operations (pass expected_version to be refused if someone else saved meanwhile) 4. deploy_staging, then get_job_status
operationsrequiredproject_idrequiredexpected_versionDrop Tables or Fields
Drop tables or fields from a project's saved schema (saves to database, does NOT deploy). DESTRUCTIVE: the next deploy drops their data. OPERATIONS (applied in order and all together): • {"op": "drop_table", "table": "clocks"} • {"op": "drop_field", "table": "parameters", "field": "is_clock"} A drop that cannot be applied (a table or field that is not there, a schema the deploy would refuse, such as a field another reads) refuses them all, naming it, and nothing is saved. The answer carries 'applied', 'diff', 'plan' and the new 'version'. WORKFLOW: 1. preview_schema_change with the same operations: check 'diff' and 'plan' 2. drop_schema_items (pass expected_version to be refused if someone else saved meanwhile) 3. deploy_staging refuses the plan and names its drops; deploy_destructive applies it, then get_job_status
operationsrequiredproject_idrequiredexpected_versionDeploy to Staging
Deploy a project's saved schema to the staging environment. This triggers: (1) Schema validation, (2) Docker image build, (3) GitHub commit, (4) Kubernetes deployment, (5) Database migrations. The operation is ASYNCHRONOUS - it returns immediately with a job_id. Use get_job_status with the job_id to monitor progress. Deployment typically takes 2-5 minutes depending on schema complexity. If deployment fails, read the job's error first: one that starts with 'RationalBloks platform error' is the platform's, not the schema's. Otherwise check: (1) Schema format is FLAT (no 'fields' nesting), (2) Every field has a 'type' property, (3) Foreign keys reference existing tables, (4) No PostgreSQL reserved words in table/field names. Use get_project_info to see if the deployment succeeded. A plan that drops data is refused, naming every table, field, entity or relationship it would drop, and every field whose type change rounds or cuts its values (a decimal with a smaller scale or turned integer, a datetime turned date): deploy_destructive applies it, a tool of its own so a client asks before it runs. One operation runs on a project at a time: while another runs, the call is refused and the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
project_idrequiredDeploy to Production
Promote staging to production (requires a paid plan): production's database migrates from the schema it runs to the one staging runs, and production runs staging's build. With staging unchanged since the last promotion, it rebuilds production with no schema change. The operation is ASYNCHRONOUS: poll the returned job_id with get_job_status. A plan that drops data is refused, naming every table, field, entity or relationship it would drop, and every field whose type change rounds or cuts its values (a decimal with a smaller scale or turned integer, a datetime turned date): deploy_destructive applies it, a tool of its own so a client asks before it runs. One operation runs on a project at a time: while another runs, the call is refused and the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
project_idrequiredDeploy a Plan That Drops Data
Deploy a plan that drops data, of a relational or a graph project. DESTRUCTIVE: the tables, fields, entities or relationships the plan drops lose their data. environment 'staging' deploys the saved schema, 'production' promotes staging. Use it only after a deploy tool (deploy_staging, deploy_production, deploy_graph_staging, deploy_graph_production) refused the plan, naming its drops, and those drops are intended. The operation is ASYNCHRONOUS: poll the returned job_id with get_job_status. One operation runs on a project at a time: while another runs, the call is refused and the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
project_idrequiredenvironmentrequiredRedeploy Project
Rebuild and roll out a project's staging environment from the schema it runs, with NO schema change, for a relational or a graph project: the current platform release, the project's settings (email, admin users) and its environment take effect. Refused (409) when the saved schema holds changes the last deploy did not apply (deploy_staging deploys those) or when nothing was deployed yet; a save that lands meanwhile is refused rather than deployed. deploy_production rebuilds production the same way when staging runs what production runs. The operation is ASYNCHRONOUS: poll the returned job_id with get_job_status. One operation runs on a project at a time: while another runs, the call is refused and the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
project_idrequiredDelete Project
Delete a project (removes GitHub repo, K8s deployments, and database). It runs as a job: poll the returned job_id with get_job_status until it is completed. One operation runs on a project at a time: while another runs, the call is refused and the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
project_idrequiredRollback Project
Rollback a project to a previous version. ⚠️ WARNING: This reverts schema AND code to the specified commit. Database data is NOT rolled back. Use get_version_history to find the commit SHA of the version you want to rollback to. After rollback, use get_job_status to monitor the redeployment. Rollback is useful when a schema change breaks deployment. One operation runs on a project at a time: while another runs, the call is refused and the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.

namerequiredproject_idrequiredGet Graph Schema
Get the graph schema definition of a project. Returns the hierarchical schema with nodes (entities) and relationships. Graph schemas define entity hierarchies and typed relationships — a different format than relational flat-table schemas. The response also says whether this saved schema is the deployed one: saved_schema_deployed is true when the last deploy applied it, false when it was saved after the last deploy (undeployed_changes then lists what deploying it would change), and null when no deployed schema is on record.

Get pre-built graph template schemas for common use cases. ⭐ USE THIS FIRST when creating a new graph project! Templates show the CORRECT graph schema format with: proper node definitions (description, flat_labels, schema with flat field definitions), relationship configurations (from, to, cardinality, data_schema), and hierarchical entity nesting. Available templates: Start from Scratch (hierarchy, flat labels, every field type), Social Network (people, organizations, content, follows), Knowledge Graph (topic hierarchy, articles, authors, concepts), Product Catalog (products, categories, suppliers, reviews). Each entry's 'schema' goes to create_graph_project as is or adapted. TIP: Study these templates to understand the correct graph schema format before creating custom schemas.

project_idrequiredCreate Graph Project
Create a new Neo4j graph database project from a hierarchical JSON schema. ⚠️ GRAPH SCHEMA FORMAT — READ BEFORE CREATING: Graph schemas define nodes (entities) and relationships, NOT flat database tables. Each field is a dict with "type" and optional "required": true (defaults to false).

List nodes of a specific entity type from a deployed graph project. Supports pagination with limit/offset. Returns nodes ordered by creation date (newest first).
limitoffsetproject_idrequiredentity_typerequiredenvironmentUpdate Graph Node
Update properties of an existing node in a deployed graph project. Only send the fields you want to change — unspecified fields remain unchanged.

Delete a node and all its relationships from a deployed graph project. ⚠️ This also removes all relationships connected to this node (DETACH DELETE).
entity_idrequiredproject_idrequiredentity_typerequiredenvironmentCreate Graph Relationship
Create a relationship between two nodes in a deployed graph project. The rel_type must match a relationship key from the project schema. Use get_graph_data_schema to see available relationship types. Example: rel_type: "authored" from_id: "alan-turing-001" to_id: "on-computable-numbers-001" data: {"year": 1936} The from_id and to_id must be entity_ids of existing nodes.

Delete a specific relationship by its internal ID. Use get_node_relationships to find relationship IDs.
rel_idrequiredrel_typerequiredproject_idrequiredenvironmentBulk Create Graph Nodes
Create multiple nodes at once (up to 500 per call). Uses Neo4j UNWIND for high performance. Essential for knowledge graph population — create hundreds of entities from a single book chapter or article. Each node needs: entity_id (unique string) and data (properties dict). Example: entity_type: "concept" nodes: [ {"entity_id": "quantum-mechanics-001", "data": {"name": "Quantum Mechanics", "field": "Physics"}}, {"entity_id": "wave-function-001", "data": {"name": "Wave Function", "field": "Physics"}}, {"entity_id": "superposition-001", "data": {"name": "Superposition", "field": "Physics"}} ]

Create multiple relationships at once (up to 500 per call). Uses Neo4j UNWIND for high performance. Essential for connecting knowledge — link hundreds of concepts, people, and events in one operation. Each relationship needs: from_id, to_id, and optional data (properties). Example: rel_type: "related_to" relationships: [ {"from_id": "quantum-mechanics-001", "to_id": "wave-function-001", "data": {"strength": "strong"}}, {"from_id": "quantum-mechanics-001", "to_id": "superposition-001", "data": {"strength": "strong"}} ]
rel_typerequiredproject_idrequiredenvironmentrelationshipsrequiredSearch Graph Nodes
Search for nodes by property values in a deployed graph project. Supports exact match and contains search (prefix value with ~ for contains). Examples: Exact: filters: {"name": "Alan Turing"} Contains: filters: {"name": "~turing"} (case-insensitive) Combined: entity_type: "person", filters: {"field": "~physics"} Without entity_type, searches ALL node types.
limitoffsetfiltersrequiredproject_idrequiredentity_typeenvironmentFull-Text Search Graph
Search across ALL string properties of ALL nodes in a deployed graph using free-text queries. Unlike search_graph_nodes (which filters by specific property), this searches every text field at once. Perfect for finding knowledge when you don't know which property contains the answer. Example: query "quantum" searches name, description, summary, notes, and all other string fields. Returns nodes with _match_fields showing which properties matched. Optionally filter by entity_type to narrow results.
limitqueryrequiredoffsetproject_idrequiredentity_typeenvironmentTraverse Graph
Walk the graph from a starting node, discovering connected knowledge. Returns all nodes reachable within max_depth hops, with their distance from the start. Essential for exploring knowledge graphs — find related concepts, trace connections, discover clusters. Example: Start from "Alan Turing", traverse outgoing relationships up to 3 hops deep: start_entity_type: "person" start_entity_id: "alan-turing-001" max_depth: 3 direction: "outgoing" Supports filtering by relationship types and direction.

Get statistics about a deployed graph: total node count, total relationship count, counts per entity type, counts per relationship type. Essential for understanding the current state of a knowledge graph before adding more data.
project_idrequiredenvironmentGet Graph Data Schema
Get the runtime schema of a DEPLOYED graph project — shows the actual entity types and relationship types available for data operations. Returns: Available entity keys (for create_graph_node, list_graph_nodes, etc.) and relationship keys (for create_graph_relationship, etc.). ⭐ USE THIS FIRST before creating nodes/relationships to know what entity_type and rel_type values are valid.
project_idrequiredenvironmentList Modules
List a project's modules and what each runs: module_id (what every module tool takes), name, type (frontblok or logicblok), repository, url, staging_status (not_deployed, deploying, deployed, failed), deployed_at, image (the image of its last successful build, named by the commit it built: <name>:<short sha>-<build time>), replicas (live pods: 0 when frozen, null while the pool is not reporting), CPU and memory, and env_var_names (the names of its environment variables, never their values).
project_idrequiredDeploy Module
Deploy a new module from a GitHub repository onto the project's resource pool: a frontblok module is a Vite frontend, a logicblok module a backend built from its Dockerfile that serves port 8000 with GET /health. Its job clones the repository (the default branch head, or git_ref), builds it and serves it at the module_url the answer names; the project's CORS origins take the module in. A private repository needs the RationalBloks GitHub App installed on it. The operation is ASYNCHRONOUS: poll the returned job_id with get_job_status. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
git_refenv_varsmemory_mbproject_idrequiredmodule_namerequiredmodule_typerequiredcpu_millicoresdockerfile_pathgithub_repo_urlrequiredRedeploy Module
Rebuild a module from its repository's default branch head and roll it out, keeping its pod count. Its data and settings are untouched; the project's API (staging and production) and its backend modules restart to take the module's CORS origin. The operation is ASYNCHRONOUS: poll the returned job_id with get_job_status, whose result names the image built (its commit); list_modules shows it once done. One operation runs on a module at a time, and none beside an operation on its project: the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
module_idrequiredUpdate Module
Rename a module, or point it at another GitHub repository, which its next redeploy builds. Pass module_name, github_repo_url or both. One operation runs on a module at a time, and none beside an operation on its project: the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
module_idrequiredmodule_namegithub_repo_urlDelete Module
Remove a module: its pods stop and it leaves the project and its CORS origins. DESTRUCTIVE. One operation runs on a module at a time, and none beside an operation on its project: the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
module_idrequiredSet Module Environment
Set a module's environment variables: {NAME: value} sets one, {NAME: null} removes one, and every variable not named is kept. A backend module restarts to take them; a frontend module rebuilds (they are build arguments). Values are stored encrypted and never returned: the answer and list_modules name the variables only. DESTRUCTIVE: a value replaced or removed cannot be read back. CORS_ORIGINS, DEPLOY_* and GITHUB_TOKEN are the platform's. The operation is a job: poll the returned job_id with get_job_status. One operation runs on a module at a time, and none beside an operation on its project: the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
env_varsrequiredmodule_idrequiredFreeze Module
Stop a module's pods (scale to 0), remembering how many it ran; unfreeze_module starts them again. Freezing a frozen module changes nothing. One operation runs on a module at a time, and none beside an operation on its project: the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
module_idrequiredUnfreeze Module
Start a frozen module's pods again, as many as it ran before the freeze. A running module is left as it is. One operation runs on a module at a time, and none beside an operation on its project: the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
module_idrequiredScale Module
Run 1 or 2 pods of a module (freeze_module stops it). One operation runs on a module at a time, and none beside an operation on its project: the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
replicasrequiredmodule_idrequiredSet Module Resources
Set a module's CPU and memory and rebuild it so its pods take them. The allocation is checked against the resource pool's capacity first; a refused one is restored. The operation is ASYNCHRONOUS: poll the returned job_id with get_job_status. One operation runs on a module at a time, and none beside an operation on its project: the refusal names the running job; wait for it with get_job_status, then call again. While RationalBloks is being updated, the call is refused with 'RationalBloks is being updated': call it again in a few minutes.
