LeanKG vs fastmcp
LeanKG: LeanKG is a local-first knowledge graph that provides accurate codebase context to AI coding tools. It indexes code, builds dependency graphs, and exposes an MCP server for direct querying. No cloud services or external databases are required.; 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.
