fastapi_mcp vs SchemaPin
fastapi_mcp: FastAPI-MCP allows you to expose your existing FastAPI endpoints as Model Context Protocol (MCP) tools. It offers native integration with FastAPI, including built-in authentication using existing dependencies, and preserves schemas and documentation.; SchemaPin: SchemaPin enables tool developers to sign schemas and skill folders with ECDSA P-256 keys, and AI agents to verify schema integrity. Public keys are discovered via .well-known/schemapin.json, and Trust-On-First-Use pinning prevents key substitution. It supports key revocation, trust bundles, and multiple languages (Python, JS, Go, Rust).
