A Firebase Crashlytics MCP server lets agents inspect crash issues, stack traces, crash events, and reports. It typically authenticates with a Google Cloud service account JSON key.

​
Prerequisites

  • A TrueFoundry account with permission to add MCP servers.
  • A Firebase project with Crashlytics enabled.
  • Permission to create service accounts in the backing Google Cloud project.

​
Create a Service Account

In Google Cloud Console, select the project that backs your Firebase project and create a service account named crashlytics-mcp. Grant:
RolePurpose
roles/firebase.viewerRead Firebase project metadata
roles/firebasecrashlytics.viewerRead Crashlytics data
roles/firebasecrashlytics.userOptional, only if tools need to update issue state
Create a JSON key and store it securely.

​
Register in TrueFoundry

Deploy the Firebase Crashlytics MCP server as a remote service or hosted stdio server. Configure the service account JSON and Firebase project ID as environment variables or secret-backed configuration expected by your MCP server implementation. Add the resulting MCP server in MCP Gateway and add collaborators. Confirm that tools are visible in the Tools section, then try them from the Agent Playground.

​
Security Notes

Treat the service account JSON as a password. Use Viewer roles unless agents must modify issue state. Revoke access by deleting the service account key in Google Cloud Console.
