Authentication Forwarding With Oauth 2 1 Jwt And Custom Auth Support

via “authentication forwarding with oauth 2.1, jwt, and custom auth support”

Expose your FastAPI endpoints as Model Context Protocol (MCP) tools, with Auth!

Unique: Implements authentication forwarding at the MCP layer by carrying HTTPRequestInfo (headers, cookies) through the tool execution pipeline, enabling transparent credential forwarding without modifying FastAPI authentication logic. Supports multiple authentication strategies (OAuth 2.1, JWT, API keys) through pluggable AuthConfig.

vs others: Preserves existing FastAPI authentication without duplication, whereas generic MCP-to-REST bridges often require separate authentication configuration or token management.
