An AI agent\ncan read a library's full API by connecting to its MCP and reading\n`docs://index`, `docs://nav`, and `docs://modules/{module}`.\n\n---\n\n## Catalog\n\n| Library | Import | Purpose | Use instead of | MCP |\n|---|---|---|---|---|\n| DAG Pipe | `dagpipe` | Deterministic state-transformation DAG engine | hand-rolled orchestration/topological ordering | `:8006` |\n| Hexa | `hexa` | Declarative DI / composition-root tooling | manual wiring, hand-written factories | `:8008` |\n| Mongo Ops | `mongo_ops` | Async MongoDB repositories, cache, populate, transactions | raw Motor CRUD and connection lifecycle | `:8007` |\n| Omniread | `omniread` | Format-agnostic fetch + parse (HTML, PDF, CSV, XLSX) | custom scrapers/parsers | `:8003` |\n| OpenAPI First | `openapi_first` | Spec-first FastAPI bootstrap, client, codegen | decorator routers and hand-written clients | `:8004` |\n| Mail Intake | `mail_intake` | Provider-agnostic read-only email ingestion | Gmail OAuth + MIME parsing | `:8002` |\n| Py JWT | `jwtlib` | JWT auth primitives (register/login/introspect) | password hashing + token code | `:8005` |\n| Doc Forge | `docforge` | Docstring compiler → MkDocs + MCP docs | custom doc generators | `:8001` |\n| Auth Server | *(service)* | Central identity service (register/login/me/introspect) | building auth endpoints yourself | *(deferred)* |\n\n## How to choose\n\n| You need to… | Use |\n|---|---|\n| persist and query documents | Mongo Ops |\n| compose dependencies | Hexa |\n| run a multi-step transformation | DAG Pipe |\n| read/parse an arbitrary input format | Omniread |\n| expose a contract-first HTTP API | OpenAPI First |\n| ingest email | Mail Intake |\n| authenticate users / verify tokens | Py JWT (+ Auth Server) |\n| generate documentation | Doc Forge |\n\n## Discovery\n\nA single **standards MCP** exposes `find_library(capability)`, which returns the\nmatching library, its import name, its \"use instead of\" guidance, and its MCP\nendpoint. Query it before writing any infrastructure.\n\n## Notes\n\n- **Hexa** is a full library with its own MCP server on `:8008`: read\n  `docs://index`, `docs://nav`, and `docs://modules/{module}` (e.g.\n  `docs://modules/hexa.container`) to discover the DI surface — `build(cls, *,\n  instances, config)` and the `PortNode` model.\n- **Auth Server** is deferred: it has no `pyproject.toml`/importable package and\n  no MCP bundle. Do not reach for it yet; `py-jwt` covers token primitives.\n- Library MCP servers expose **documentation resources** (not executable tools):\n  they tell an agent the available API surface so it does not invent code.\n",
