Why MCPProxy?
- Scale beyond API limits ā Federate hundreds of MCP servers while bypassing Cursor's 40-tool limit and OpenAI's 128-function cap.
- Save tokens & accelerate responses ā Agents load just one
retrieve_toolsfunction instead of hundreds of schemas. Research shows ~99 % token reduction with 43 % accuracy improvement. - Advanced security protection ā Automatic quarantine blocks Tool Poisoning Attacks until you manually approve new servers.
- Works offline & cross-platform ā Native binaries for macOS (Intel & Apple Silicon), Windows (x64 & ARM64), and Linux (x64 & ARM64) with system-tray UI.
