I built MCPProxy to make AI agents (Cursor, Claude Desktop, etc.) more useful.
- Scale beyond limits – federate hundreds of MCP servers while bypassing Cursor’s 40-tool and OpenAI’s 128-function caps.
- Save tokens & reduce latency – agents load only a few tool functions on demand instead of hundreds of schemas.
- Security quarantine – every new server is auto-quarantined to block Tool-Poisoning Attacks until you approve it.
Cross-platform desktop app with native tray UI; works offline; MIT-licensed.
Quick start (console):
1) brew install smart-mcp-proxy/mcpproxy/mcpproxy
2) mcpproxy # HTTP server on :8080 + tray
