fastmcp vs sourcey
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.; sourcey: Sourcey is a static documentation generator that consolidates various source formats like OpenAPI, Doxygen, and Markdown into a single, self-owned HTML site. It renders all content at build time, ensuring no runtime dependencies or API calls for your documentation.
