Launch Chrome with Remote Debugging Enabled
Open your operating system’s terminal or command prompt and start Chrome with the remote debugging port (9222):- Windows:
"C:\Program Files\Google\Chrome\Application\chrome.exe" --remote-debugging-port=9222 - Mac:
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222 - Linux:
google-chrome --remote-debugging-port=9222
- Windows:
Copy Debug URL Value
By default, the debug interface is available at:http://localhost:9222Determine Connection Type
- If running everything on one machine (or you are using Docker with port 9222 forwarded): use
directordockeras the connection type. - If your browser runs in a different OS (for example, via WSL) and you are tunneling the port, use
ssh-tunnel.
- If running everything on one machine (or you are using Docker with port 9222 forwarded): use
Set Values in the FastMCP Connection Interface
In the FastMCP integration settings (using the "Install Now" button), enter the following values:CHROME_DEBUG_URL: Set this to your debugging URL (usuallyhttp://localhost:9222).CHROME_CONNECTION_TYPE: Set this to one of:direct,ssh-tunnel, ordocker.- (Optional)
CHROME_ERROR_HELP: You may add a custom error message to display if a connection fails (for example, suggest checking the debugging port or tunneling status).
Example values:
CHROME_DEBUG_URL:http://localhost:9222CHROME_CONNECTION_TYPE:direct
For WSL/SSH Tunnel:
- Launch Chrome on Windows with remote debugging
- Run the SSH tunnel in your WSL shell:
ssh -N -L 9222:localhost:9222 windowsuser@host - Set
CHROME_CONNECTION_TYPEtossh-tunnel - (Optionally) set
CHROME_ERROR_HELPto:Make sure the SSH tunnel is running: ssh -N -L 9222:localhost:9222 windowsuser@host
Summary:
You do not need an API key or special token for this setup. Once Chrome is running with remote debugging, all you need to do is copy the correct debug URL and connection type into the FastMCP interface for successful integration.
