### Description (declared)

# pontifex-mcp

The security and governance layer for MCP servers, built on the official [MCP Python SDK](https://github.com/modelcontextprotocol/python-sdk).

`pontifex-mcp` lets you build [MCP](https://modelcontextprotocol.io) servers that connect AI agents to
real systems without giving up control over who can call what. You write the tools; it handles
authentication, per-caller scopes, rate limits, and a full audit trail.

## Key features

- **Secure by default** — OAuth 2.1 JWTs *and* `sk_…` API keys; every tool call is authenticated.
  Any OIDC provider (Auth0, Entra, Clerk, Keycloak).
- **Least-privilege scopes** — `namespace:resource:action`, checked before every call. Callers can't
  widen their own access.
- **Auditable** — every call recorded: who, what, when, data source, cache hit, latency.
- **Standards-based** — RFC 9728 discovery + `WWW-Authenticate`; MCP clients bootstrap auth on their own.
- **Resilient** — per-caller rate limiting, adapter failover, circuit breaking.
- **Observable** — Logfire / OpenTelemetry tracing and metrics wired in.
- **Drop-in connectors** — generate governed tools from an OpenAPI spec (code or config), with optional
  per-user OAuth token exchange (RFC 8693) to the downstream.
- **Built on the MCP SDK** — keep its tools, protocol, and transports; add the controls a production
  server needs.
- **Coding-agent friendly** — bundles an official agent skill (`uvx library-skills`) so your coding
  agent builds on guidance that matches your installed version.

Asymmetric-only JWT validation, generic auth errors, and no token claim can escalate a caller.

## Install

```bash
pip install pontifex-mcp     # or: uv add pontifex-mcp
```

Requires Python 3.12+. The floor below needs nothing else; Postgres and Redis come in only
when you turn on API-key auth.

## Start in a few lines

`PontifexMCP` is a drop-in subclass of the MCP SDK's `FastMCP`. The floor needs no database,
no Redis, and no auth — the caller is anonymous and every ca…
