{

"mcpServers": {

  "firebase": {

    "command": "npx",

    "args": \["-y", "firebase-tools@latest", "mcp"\]

  }

}

}

That was the config I used provided by the firebase studio documentation. I logged in using the firebase login --no-localhost command in the terminal. Not sure If I am missing something

I am having the same issue, and when I try to run the firebase MCP in my local VSCode environment I am also getting similar errors, its like the Firebase MCP services are unreachable.

So all MCP are going to be unreachable UNTIL you authorize your Firebase using a login. I know it’s dumb. What you do is, when you are in the vscode mode, open the MCP icon, keep clicking the edit config until the grant access show. ATTACHED here. then grant it, then it should be good. WEIRD but WORKS.

This did not work for me, but i have gotten sick of this issue so i dug a bit, turns out the access token had expired for the cloud stuff, i had to run…

gcloud auth login

Once i went thru that and reloaded the workspace it showed the grant access dialog and was able to connect to the MCP server.
