Built on [FastMCP v3](https://gofastmcp.com/) and the [`ch-api`](https://github.com/release-art/ch-api) async client.\n\n## Overview\n\n- **22 read-only tools** across five domains: search, companies, officers, PSCs (persons with significant control), and filings.\n- **Two transports**: HTTP (Starlette/uvicorn) for remote MCP clients, and stdio for local integrations.\n- **OAuth2 via Auth0**, with three modes:\n  - `none` — no authentication (local dev / trusted-ingress only).\n  - `remote` — JWT verification only (the MCP server trusts an upstream Auth0 tenant).\n  - `proxy` — full OAuth proxy with dynamic client registration; tokens are persisted to Azure Blob Storage, encrypted with Fernet.\n- **Scope-based authorization**: tools tagged `ch_api:read` require the `ch-api:read` scope in the access token. Enforcement is per-tool, so `initialize` and `tools/list` remain reachable by unauthenticated clients.\n- **Structured responses**: Pydantic models synthesised by reflection from `ch-api` types. Every response carries a typed `refs` sub-object holding the resource IDs (company number, charge id, document id, …) extracted from the upstream `links` block — chain tool calls by feeding those IDs straight into the next tool's input.\n\n## Tools\n\n| Module | Tools |\n|--------|-------|\n| [`search.py`](src/ch_mcp/server/search.py) | …","publisher":null,"homepage":"https://docs.release.art/ch-api/","repository":"https://github.com/release-art/ch-api/","version":"0.0.6","license":null,"protocols":["mcp"],"tags":["mcp"],"pricing":null,"endpoints":[{"url":"pypi:companies-house-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi"}},"derived":{"capabilities":[{"slug":"security.identity","name":"Identity & Access","confidence":1,"provenance":"derived"}],"categories":["security"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"companies-house-mcp","registry":"pypi","observedAt":"2026-09-09T12:30:17.680Z","publishedAt":"2026-04-29T18:05:19.844351Z","latestVersion":"0.0.6"}},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"companies-house-mcp","url":"https://pypi.org/project/companies-house-mcp/","firstSeenAt":"2026-09-09T12:27:21.032Z","fetchedAt":"2026-09-09T13:20:07.812Z","normalizedAt":"2026-09-09T13:20:07.812Z"}]},"firstSeenAt":"2026-09-09T12:27:21.032Z","updatedAt":"2026-09-09T12:30:17.680Z"}
