Best FastAPI MCP Servers
FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints.
Why this server?
Provides middleware for FastAPI backends to enforce HTTP 402 paywalls, allowing AI agents to pay per request.
Why this server?
Probes and analyzes FastAPI backend endpoints to diagnose blank pages, empty data, and contract mismatches, providing root cause and fix hints.
qa-probeofficial
AlicenseAqualityCmaintenanceProbes your live API and classifies why each endpoint failed (root cause, evidence, and a calibrated confidence level), exposed over MCP so your AI assistant debugs from evidence instead of guessing. Works with FastAPI, Express, Next.js, tRPC, and GraphQL.89 npm2Apache 2.0Why this server?
Supports deployment of FastAPI applications to Varity with automatic backend service wiring.
