Watch this server yourself

If you run this server, put the proxy in front of it. It pins these exact fingerprints on first connect and stops the session if they move.

npx --yes mcp-pin@0.1.0 -- <your @mozilla/firefox-devtools-mcp command>

Or subscribe to this page's RSS feed to be told when it changes.
