Add Firebase MCP server Claude plugin configuration

[charlotteliang]

Here's the complete step-by-step guide to install and test your Firebase MCP plugin locally:

Step 1: Validate the marketplace configuration

From your terminal in the firebase-tools directory:

claude plugin validate .

This will check if your marketplace.json is properly formatted.

Step 2: Open Claude Code and add the marketplace

Start Claude Code, then run this command in the Claude Code interface:

/plugin marketplace add /Users/chliang/github/firebase-tools

Or if you're already in a Claude Code session within the firebase-tools directory:

/plugin marketplace add .

You should see a confirmation that the marketplace was added.

Step 3: List available marketplaces (optional)

To verify the marketplace was added:

/plugin marketplace list

You should see firebase in the list.

Step 4: Install the plugin

/plugin install firebase-mcp-server@firebase

Step 5: Verify the plugin is installed

Check installed plugins:

/plugin list

You should see firebase-mcp-server@firebase in the list.

Step 6: Test the MCP server

Check if the Firebase MCP server is running:

/mcp list

You should see a firebase MCP server listed. You can now interact with Firebase services through the MCP
interface in Claude Code.

Step 7: Test Firebase functionality

If you have a Firebase project in your current directory, try asking Claude Code to interact with Firebase.

Summary of Changes

Hello @charlotteliang, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces the foundational configuration required to integrate the Firebase Model Context Protocol (MCP) server as a plugin within the Claude Code environment. The primary goal is to empower developers to seamlessly manage and interact with Firebase services directly from Claude Code, thereby streamlining the development workflow for Firebase-backed projects. The changes are encapsulated in a new marketplace configuration file that defines the Firebase plugin and its operational parameters.

Highlights

• New Plugin Configuration: A new .claude-plugin/marketplace.json file has been added to configure the Firebase MCP server as a Claude plugin.
• Firebase MCP Server Integration: This configuration enables Claude Code to interact with various Firebase services, such as Firestore, Realtime Database, Cloud Functions, and Hosting, through the Firebase Model Context Protocol (MCP) server.
• Local Testing Guide: The pull request description includes a comprehensive step-by-step guide for local installation and testing of the newly configured Firebase MCP plugin.

Code Review

This pull request adds a Claude plugin marketplace configuration file for the Firebase MCP server. This allows local development and testing of the MCP server as a Claude plugin. My review identifies two issues: one high-severity issue regarding the command used to launch the server which would prevent testing local changes, and one medium-severity issue regarding a hardcoded version number that will create a maintenance burden.

[gemini-code-assist]

The command and args are configured to run npx -y firebase-tools .... This will download and execute the latest version of firebase-tools from npm, rather than using the local source code from this repository. This will prevent developers from testing their local changes to the MCP server.

To run the local version of firebase-tools, the command should directly execute the compiled script. Assuming the main script is at lib/bin/firebase.js after building, the configuration should be updated. This is a reasonable expectation for local development.

          "command": "node",
          "args": [
            "./lib/bin/firebase.js",
            "mcp",
            "--dir",
            "."
          ],
