Why MCPProxy?

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