A Gmail MCP server with native multi-account support. Manage multiple Gmail accounts from a single server instance.
Unlike other Gmail MCPs that require running separate server instances per account, this one lets you specify which account to use on each tool call—making it easy to manage personal and work inboxes from Claude Code, Cursor, or any MCP client.
- Multi-account support - Single server instance, unlimited Gmail accounts
- Account aliases - Use friendly names like "work" or "personal" instead of email addresses
- Full Gmail API - Search, read, send, label, and manage emails
- Batch operations - Bulk modify or delete emails efficiently
- Auto token refresh - Handles OAuth token refresh automatically
npm install -g gmail-mcp-multiOr run directly with npx:
npx gmail-mcp-multiYou'll need OAuth credentials from Google Cloud Console:
- Go to Google Cloud Console
- Create a new project (or use existing)
- Enable the Gmail API
- Create OAuth 2.0 credentials (Desktop app type)
- Download the credentials JSON
Create ~/.gmail-mcp/oauth-keys.json with your OAuth credentials.
Claude Code (~/.claude/settings.json):
{
"mcpServers": {
"gmail": {
"command": "npx",
"args": ["gmail-mcp-multi"]
}
}
}Once the MCP is running, use the authenticate tool:
authenticate({ alias: "work", email: "[email protected]" })
authenticate({ alias: "personal", email: "[email protected]" })
search_emails({ account: "work", query: "in:inbox is:unread" })
search_emails({ account: "personal", query: "from:mom" })
All tools that interact with Gmail require an account parameter (alias or email).
