fastmcp vs McpVanguard

fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.; 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.
