# Cursor Setup

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

### 1. Install and Verify Firebase Skills

Check if the skills are already installed before proceeding:

1. **Check Local skills**: Run `npx skills list --agent cursor`. If the output
   includes `firebase-basics`, the skills are already installed locally.
1. **Check Global skills**: If not found locally, check the global installation
   by running:
   ```bash
   npx skills list --global --agent cursor
   ```
   If the output includes `firebase-basics`, the skills are already installed
   globally.
1. **Install Skills**: If both checks fail, run the following command to install
   the Firebase agent skills:
   ```bash
   npx skills add firebase/agent-skills --agent cursor --skill "*"
   ```
   *Note: Omit `--yes` and `--global` to choose the installation location
   manually. If prompted interactively in the terminal, ensure you send the
   appropriate user choices via standard input to complete the installation.*
1. **Verify Installation**: Re-run the checks in steps 1 or 2 to confirm that
   `firebase-basics` is now available.

### 2. Configure and Verify Firebase MCP Server

The MCP server allows Cursor to interact directly with Firebase projects.

1. **Locate `mcp.json`**: Find the configuration file for your operating system:

   - Global: `~/.cursor/mcp.json`
   - Project: `.cursor/mcp.json`

   *Note: If the directory or `mcp.json` file does not exist, create them and
   initialize the file with `{ "mcpServers": {} }` before proceeding.*

1. **Check Existing Configuration**: Open `mcp.json` and check the `mcpServers`
   section for a `firebase` entry.

   - It is already configured if the `command` is `"firebase"` OR if the
     `command` is `"npx"` with `"firebase-tools"` and `"mcp"` in the `args`.
   - **Important**: If a valid `firebase` entry is found, the MCP server is
     already configured. **Skip step 3** and proceed directly to step 4.

   **Example valid configurations**:

   ```json
   "firebase": {
     "command": "npx",
     "args": ["-y", "firebase-tools@latest", "mcp"]
   }
   ```

   OR

   ```json
   "firebase": {
     "command": "firebase",
     "args": ["mcp"]
   }
   ```

1. **Add or Update Configuration**: If the `firebase` block is missing or
   incorrect, add it to the `mcpServers` object:

   ```json
   "firebase": {
     "command": "npx",
     "args": [
       "-y",
       "firebase-tools@latest",
       "mcp"
     ]
   }
   ```

   *CRITICAL: Merge this configuration into the existing `mcp.json` file. You
   MUST preserve any other existing servers inside the `mcpServers` object.*

1. **Verify Configuration**: Save the file and confirm the `firebase` block is
   present and properly formatted JSON.

### 3. Restart and Verify Connection

1. **Restart Cursor**: Instruct the user to restart the Cursor application.
   **Stop and wait** for their confirmation before proceeding.
1. **Confirm Connection**: Check the MCP server list in the Cursor UI to confirm
   that the Firebase MCP server is connected.
