args = ["-y", "firebase-tools", "mcp"]

2. Sign in

Run codex mcp login <name> to complete OAuth for a remote server. Firebase runs locally; set any credentials Google asks for before starting Codex.

3. Try it

Ask Codex for something Firebase can do. Firebase-aware tools for projects, Auth, Firestore, Hosting and more, via the Firebase CLI. Approve the first tool call and check the result before allowing write actions automatically.

· Each server is a [mcp_servers.<name>] table in config.toml.
· Use enabled_tools or disabled_tools to keep the tool list short.
