Cloud architecture and migration planning with costs, controls, evidence, and deployable IaC.
Overview
Cloudwright turns a plain-English prompt into a typed cloud architecture spec with costs, compliance controls, diagrams and deployable IaC, exposed to agents…
- What you can do
- Design and modify architectures from a prompt, producing a typed YAML spec
- Estimate per-component, region-aware costs and run offline review, lint, score, policy and security checks
- Map findings to HIPAA, SOC 2, PCI-DSS, FedRAMP, GDPR, ISO 27001 and NIST 800-53 control IDs, with OSCAL output
- Export Terraform, OpenTofu, Pulumi or CloudFormation and validate it without applying
- Plan and verify migration waves with evidence gates, and manage sessions and diagrams
- When to use it
- Useful when an assistant is drafting cloud designs or migration plans for AWS, GCP, Azure or Databricks and needs cost estimates, compliance mapping and reviewable infrastructure code inside the same loop. Most checks run offline, so it also suits review work without a model key.
- Requirements
- Local Python package (cloudwright-ai-mcp, Python 3.12+) run over stdio. The design, modify, chat and adr commands need ANTHROPIC_API_KEY or OPENAI_API_KEY; other commands run offline. Checkov is used only if present on PATH.
Installation
In SourceWeft
- Open Cloudwright in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

Cloudwright
Design a cloud architecture or plan a migration. Get costs, controls, code, and checked evidence.
[PyPI] [CI] [License: MIT] [Python 3.12+] [xmpuspus/cloudwright MCP server]
Cloudwright turns one line of English into a typed spec, a cost breakdown, a control-mapped compliance report,
and infrastructure code. A source estate and target become ordered migration waves, explicit costs,
and evidence gates. It covers AWS, GCP, Azure and Databricks across 114 service keys. Only design, modify,
chat and adr call a model. Every other command runs offline and needs no API key.

A prompt produces a spec, a cost, a control-mapped report, and Terraform
- Spec. Typed YAML you commit, diff and review. Everything below reads from it.
- Cost. Per component and region-aware, with a confidence flag on every line.
- Compliance. HIPAA, SOC 2, PCI-DSS, FedRAMP, GDPR, ISO 27001 and NIST 800-53 control IDs.
- Infrastructure code. Terraform, OpenTofu, Pulumi (TypeScript or Python) and CloudFormation.
- Diagrams. ASCII, Mermaid, D2, and a web canvas you can edit by hand.
- An MCP server, so any coding agent runs the same checks inside its own loop.
Exports carry safe defaults. S3 gets a public-access block, SSE and versioning. RDS gets encryption, multi-AZ and deletion protection. EC2 gets IMDSv2. A compliance framework overrides the workload profile, and always forces encryption and high availability.
Quickstart
Add --json before any subcommand for machine-readable output, or --stream to watch tokens arrive. Set ANTHROPIC_API_KEY or OPENAI_API_KEY for the four commands that need a model.
Migration plans stop when evidence is missing
The migration model covers infrastructure, applications, data, platforms, networks, facilities, and business services in one dependency graph. It works for on-premises, cloud, cross-cloud, hybrid, data-center, and application moves. It plans and checks work. It never copies data, applies infrastructure, switches traffic, or runs a cutover.
The core has no telco fields. The first proof project selects an external ph_telco pack for subscriber,
billing, usage-record, number-porting, privacy, recovery, and source-shutdown gates. A manufacturing ERP
fixture proves the same planner works without that pack. Missing blocking evidence changes the result to
closed: false and makes migrate verify exit with code 2. Each evidence file carries the deterministic
assessment ID, so observations from an older target or cutover plan cannot close a revised assessment.
MCP clients use the same engine through plan_migration and verify_migration in the migration tool group.
See Migration planning and evidence for the file contract, Python API, HTTP routes, domain-pack format, limits, and recording commands.
Every finding carries the control ID it violates
Other tools scan infrastructure after you deploy it. Cloudwright maps each finding to its control before any
resource exists. The fix then costs a spec edit instead of a change ticket. HIPAA 164.312(a)(2)(iv), SOC 2 CC6.1
and FedRAMP SC-28 come from the built-in scanner, with no extra tooling. Checkov folds into the same report
when it sits on your PATH.
--oscalwrites an OSCAL 1.1.2 component-definition with deterministic UUIDs.--traceabilityprints the chain from component to resource to control to status.cloudwright planrunsterraform validateagainst the export, and never applies.
The review needs no API key and no network
cloudwright review runs the scorer, the linter and the validator over a spec, and returns one severity-ranked
report. The same three critics run inside cloudwright design. When blocking findings survive generation, the
architect repairs the spec once and records the change in spec.metadata.critique. Pass
Architect(repair=False) to turn that off.
Canvas edits never call the model, so they are instant and free
Add, drag, connect, edit and delete are deterministic frontend mutations. The Catalog drawer serves the resource
list per provider and five approved multi-resource modules. Its standards check flags orphan connections,
partial modules and missing tags. An intact module exports as a single Terraform module block, with the
catalog's pinned source and version.
One MCP server reaches 11 coding agents
Do not hand-write the config. cloudwright integrate emits it for Claude Code, Cursor, Cline, Windsurf, GitHub
Copilot, Zed, Codex CLI, Junie, Kiro and Antigravity. Aider gets a CLI-pipe recipe instead, because it speaks
no MCP. Every client wants a different shape: Zed wants context_servers, Copilot wants servers, and Codex
wants a TOML table.
The server exposes 24 tools in 10 groups: design, cost, validate, analyze, export, session, review, compliance, plan and migration. Full matrix in docs/integrations.md.
Offline commands grade, scan, compare, and plan
lint runs 10 anti-pattern checks. score grades 5 dimensions. analyze reports blast radius and single
points of failure. policy enforces policy-as-code with 9 built-in rules. security scans the spec and the
exported HCL. drift compares a design against a tfstate, and --remediate turns the gap into a cost,
compliance and plan preview.
review, compliance and plan are above. See docs/cli-reference.md.
Python API
v1.10.0 adds migration planning with evidence-based closure
- One model covers the full estate. Infrastructure, data, applications, platforms, networks, facilities, and business services share one dependency graph.
- Dependencies determine the waves. The planner schedules prerequisites first, rejects cycles, checks rollback paths, and reports unresolved mappings.
- Closure needs evidence. Missing or failed blocking observations prevent closure and make
migrate verifyreturn exit code 2. - Industry rules stay outside the engine. Optional YAML packs add acceptance gates without adding industry fields to the core.
- PH telco is the first proof. The product remains industry-neutral. A manufacturing ERP fixture runs through the same planner with no domain pack.
Earlier releases added control-ID mapping and plan (v1.5.0), the self-correcting architect and OSCAL
(v1.6.0), cloudwright integrate (v1.7.0), the responsive dark-theme canvas (v1.8.0), and measured
canvas interaction fixes (v1.9.0). Full history in CHANGELOG.md.
