# MCP Gmail Installer

This skill installs the Gmail MCP server into the current project.

## Installation Procedure

When the user asks to install Gmail MCP:

1. **Check for existing `.mcp.json`** in the project root
2. **Merge configuration** - Add this server to `mcpServers`:

```json
{
  "gmail": {
    "command": "node",
    "args": ["${ONEDRIVE_MCP_PATH}/Gmail-MCP-Server/dist/index.js"]
  }
}
```

3. **If `.mcp.json` doesn't exist**, create it with the full structure:

```json
{
  "mcpServers": {
    "gmail": {
      "command": "node",
      "args": ["${ONEDRIVE_MCP_PATH}/Gmail-MCP-Server/dist/index.js"]
    }
  }
}
```
