MCP Cdp runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 22 Sep 2026.
Safe-by-default MCP that drives an Electron/Chrome app over CDP: DOM, console, network, input.
Today is the operative word: we check MCP Cdp every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
CDP_PORT (The --remote-debugging-port your app/browser exposes (default 9222).), CDP_HOST (Host serving the DevTools endpoint (default 127.0.0.1; non-loopback needs CDP_ALLOW_REMOTE).), CDP_MODE (Access mode: read-only | read-write | admin. Starts read-only; interactions need read-write.), CDP_ALLOW_EVAL (Set true to allow the evaluate tool (arbitrary JS) — admin mode only. Default false.), CDP_TARGET_ALLOWLIST (Comma-separated URL patterns; interactions are confined to matching targets. Empty = all.), CDP_DRY_RUN (Set true to log interactions without dispatching them to the browser.).
The author declared them in the registry entry; get the values from the project itself.
