The demo above shows the embedded web UI. The MCPProxy core is a single binary for macOS, Linux, and Windows — the web UI ships inside it, with no extra service to run. On macOS, an optional menu‑bar app adds one‑click convenience (start/stop, server health, quarantine, logs).

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 retrievetools 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.
- Pluggable security scanners – Run Snyk, Semgrep, Trivy, Cisco, and other Docker-based scanners against quarantined servers before you approve them; findings are normalized to SARIF with a composite risk score. See Security scanner plugins.
- Works offline & cross-platform – A single core binary for macOS (Intel & Apple Silicon), Windows (x64 & ARM64), and Linux (x64 & ARM64), with the web UI embedded. macOS additionally ships an optional menu-bar app.
