Claude Code Setup

To get the most out of Firebase in Claude Code, follow these steps to install the agent skills and the MCP server.

Recommended Method: Using Plugins

The recommended method is using the plugin marketplace to install both the agent skills and the MCP functionality.

Check if the plugins are already installed before proceeding:

Check Existing Skills: Run npx skills list --agent claude-code to check for local skills. Run npx skills list --global --agent claude-code to check for global skills. Note whether the output includes firebase-basics.
Check Existing MCP Configuration: Run claude mcp list -s user and claude mcp list -s project. Note whether the output of either command includes firebase.
Determine Installation Path:
- If both skills and MCP configuration are found, the plugin is fully installed. Stop here and skip all remaining setup steps in this document.
- If neither are found, proceed to step 4.
- If only one is found (e.g., skills are installed but MCP is missing, or vice versa), stop and prompt the user. Explain the mixed state and ask if they want to proceed with installing the Firebase plugin before continuing to step 4.
Add Marketplace: Run the following command to add the marketplace (this uses the default User scope):
```
claude plugin marketplace add firebase/agent-skills
```
Install Plugins: Run the following command to install the plugin:
```
claude plugin install firebase@firebase
```
Verify Installation: Re-run the checks in steps 1 and 2 to confirm the skills and the MCP server are now available.

Restart Claude Code: Instruct the user to restart Claude Code. Stop and wait for their confirmation before proceeding.
