## Connect

- MCP server: https://a2uicatalog.ai/mcp — no API key, no signup. `POST` speaks JSON-RPC 2.0

(Streamable HTTP). `GET` with `Accept: application/json` returns a live server descriptor

(every tool, current rate limits).

+ - Documentation MCP server: https://a2uicatalog.ai/mcp-docs — a separate identity

+ (`a2uicatalog-docs`) exposing `search_docs(query)`/`list_docs()` over this product's own

+ docs, distinct from the product server above.

- REST: `GET /spec.json` (full atom vocabulary), `GET /catalogue/atoms-json-schema.json`

(strict per-atom JSON Schema for constrained decoding), `POST /api/compose` (natural

language to atom blocks).
