Mcpproxy Go

Mcpproxy Go is an open-source MCP (Model Context Protocol) server and smart proxy designed to boost AI agents with fast, secure, and highly scalable tool discovery. It enables AI assistants (like Claude, Cursor, and other MCP-compatible clients) to access hundreds of tools and resources efficiently by federating multiple MCP servers and utilizing powerful BM25 search for relevant tool selection. Built with robust quarantine security and massive token savings (~99% reduction), it also features audit logging, sharp API federation, local/offline and cross-platform support, and a system tray UI. It is ideal for developers, AI researchers, tinkerers, and teams that want to extend, secure, or self-host their AI tool chains in advanced workflow scenarios.
