A Model Context Protocol (MCP) server functioning as a Full-Stack Context Bridge for FastAPI, APIRouters, and Pydantic codebase introspection.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"fastapi-mcp-server","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
