McpVanguard vs fastapi_mcp
McpVanguard: McpVanguard is a security gateway for MCP agents that inspects traffic in real time and enforces security policy before sensitive calls reach the underlying tool. It works in local-first mode wrapping stdio MCP servers and in gateway mode exposing hardened SSE and Streamable HTTP endpoints. Transparent integration without rewriting existing MCP servers.; 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.
