Sub-5ms topological 4D associative memory coprocessor for LLMs and multi-agent swarms.
The publisher's own server: Memory.fit
Hosted persistent memory service that lets an assistant store, search and trace facts across sessions and agent swarms.
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/io.github.Calera-Labs%2Ficx-mcp/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.

When prompt budget is constrained or when operating in tight 2k–4k LLM viewports, callers can opt into 1D Holographic Ribbon Mode (format: "ribbon"):
This drops prompt injection token consumption by >40% compared to uncompressed fact bags while preserving 100% causal grounding and transitive deductive pathways.

actionrequiredpayloadrequiredsurfacerequiredExecute Programmatic CodeAct Script
Executes programmatic Python code inside a sandboxed execution runtime with direct sub-5ms native access to persistent Volumetric Lattice Network memory via the global 'icx' object (icx.search, icx.recall, icx.quote, icx.remember, icx.stats, icx.contradictions). Use this tool for complex multi-hop aggregations, mathematical calculations, contract/financial analytics, and large dataset filtering off-context without bloating the LLM prompt window. Only printed output (print()) crosses into the conversation context. Mutating/read operation. Requires X-License-Key authentication.
coderequiredspace_idtimeout_msGet Connected Document Content
Retrieves the full on-demand text, markdown, or code content of a connected document, file, page, or issue from external services (Google Drive doc, Notion page, GitHub file, GitLab file, Linear ticket). Read-only operation. Requires X-License-Key authentication.
typeresource_idrequiredconnector_idInspect Connector Grounded Facts
Inspects the active grounded facts and simplicial statements currently tracked in Volumetric Memory for a specific connector or data source. Read-only operation. Requires X-License-Key authentication.
limitconnector_idrequiredInspect Memory Space Telemetry
Audits and returns real-time diagnostic telemetry for a partitioned memory space, including active node counts, total synapses, grounded facts, memory state, and contradiction alarms. Use this tool to monitor memory partition health, verify document ingestion, check storage capacity, or detect contradiction alarms in a space. Do NOT use for querying memory content (use icx_recall_scoped or icx_quote_slot). Read-only operation with zero side effects. Requires X-License-Key authentication.
space_idList Auto-Sync Connectors
Lists all active cloud changefeed connectors (GitHub, GitLab, Notion, Google Drive, Linear, Slack, PostgreSQL) registered for the tenant. Read-only operation. Requires X-License-Key authentication.
Takes no parameters.
Multi-Hop Transitive Causal Walk
Executes a single-pass sub-5ms multi-hop simplicial causal walk across the Volumetric Lattice Network and Ontology relations. Traces transitive dependency chains (e.g. A -> B -> C -> D -> Leaf) and resolves temporal state overrides (retaining dynamic multi-policy mutations). Read-only operation. Requires X-License-Key authentication.
max_hopsspace_idroot_entitystart_entitytarget_entitytarget_relationO(1) Instant Source Memory Purge
Executes O(1) instant memory unlinking and revocation of all facts, simplices, and document associations learned from a specific data source or connector without requiring model retraining. Mutating operation. Requires X-License-Key authentication.
space_idsource_idrequiredVerbatim Register Quoting
Retrieves exact character-for-character verbatim text and cryptographic SHA-256 hashes from document registers by document family and 1-based slot index without AI paraphrasing. Optional start (0-based character offset) and length (character count) return a verbatim slice of the stored slot text. The slice is the exact stored characters, not a summary. Omit both start and length to return the whole slot. If start or length is out of range, the call errors and does not clamp. sha256 and parent_sha256 are the SHA-256 of the entire stored slot. slice_sha256 is the SHA-256 of the characters returned in exact_quote. Use this tool when exact contractual wording, statutory clauses, license keys, or immutable code revisions must be quoted verbatim without AI modification. Do NOT use for semantic question answering (use icx_recall_scoped), and do NOT use for keyword exploration (use icx_search_facts). Read-only operation with zero side effects. Requires X-License-Key authentication.
indexrequiredstartfamilyrequiredlengthspace_idScoped Memory Recall
Performs semantic search across persistent long-term memory to retrieve grounded facts, relevant citations, and source documents matching a natural language question. Use this tool when answering questions about previously saved project specifications, codebase decisions, user preferences, or documents. Do NOT use for saving new facts (use icx_remember), do NOT use for raw keyword lookup (use icx_search_facts), and do NOT use for exact character-for-character verbatim quotes (use icx_quote_slot). Read-only operation with zero side effects. Requires X-License-Key authentication.

Registers a new cloud webhook changefeed connector or remote MCP server for continuous epistemic auto-sync with AES-256-GCM secret vaulting and HMAC signature verification. Mutating operation. Requires X-License-Key authentication.
namerequiredtyperequiredtoolsapi_keyauth_tokentarget_urirequireddefault_riskwebhook_secretMemorize Document or Fact
Stores text documents, code snippets, architectural decisions, and factual knowledge into persistent long-term memory partitioned by space_id. Use this tool when saving important facts, project conventions, API keys, user preferences, or documentation for future sessions. Do NOT use for retrieving stored memory (use icx_recall_scoped for semantic QA, icx_search_facts for keyword lookup, or icx_quote_slot for verbatim quotes). Ingestion is additive and non-destructive: creates new memory nodes without overwriting or mutating existing records. Requires X-License-Key authentication.
textrequiredfamilyfilenamespace_idReset Conversation History
Clears conversational dialogue turn history for a session while strictly preserving all underlying persistent memory, learned facts, and document registers in the memory space. Use this tool when switching conversation topics or clearing dialogue context between independent tasks while retaining stored knowledge. Do NOT use for wiping persistent memory (persistent memory is preserved by design). Mutates session turn state but leaves long-term memory intact. Requires X-License-Key authentication.
space_idSearch Simplicial Lattice Facts
Performs keyword and token search across persistent memory to discover entities, names, and matching terms within a memory space. Use this tool for entity exploration, keyword discovery, and locating specific identifiers or variables in memory. Do NOT use for answering natural language questions (use icx_recall_scoped), and do NOT use for writing data (use icx_remember). Read-only operation with zero side effects. Requires X-License-Key authentication.
limitqueryrequiredspace_idMulti-Agent Swarm Shared State
Manages the persistent shared variable namespace (V_t) and mutex leases for collaborative swarms of autonomous agents (Cursor, Claude, Cline, OpenDevin). Reads, writes, or atomic CAS-swaps typed state objects (AST graphs, data tables, audit flags) without prompt re-serialization. Mutating/read operation. Requires X-License-Key authentication.
keyvalueagent_idspace_idoperationrequiredexpected_versionAuto-Sync Audit Logs
Retrieves historical synchronization events, deltas processed, facts learned, and sub-2ms latency telemetry for compliance and audit auditing. Read-only operation. Requires X-License-Key authentication.
Takes no parameters.
Crystallize Incremental Delta
Extracts fine-grained deltas between previous text/document state and updated state, and crystallizes them into the Volumetric Memory lattice in sub-2ms on CPU with automatic secret scrubbing and SHA-256 deduplication. Use this tool for continuous incremental sync of code files, documentation, PRDs, and database schemas. Mutating operation. Requires X-License-Key authentication.
urinew_textrequiredold_textspace_idsource_idTrigger Connector Sync
Triggers an on-demand active pull and delta synchronization for a registered connector (GitHub, GitLab, Notion, Google Drive, Linear, Slack, PostgreSQL). Fetches live commits, issues, PRDs, or DDL schemas and crystallizes deltas into persistent Volumetric Memory in sub-2ms. Mutating operation. Requires X-License-Key authentication.
