google-contacts-mcp

MCP server for Google Contacts - list, search, and manage contacts.

Use Cases

Email lookup: "See the latest JIRA ticket that's come in. Can we email Sarah from the security team to get their input?" → finds Sarah's email and drafts the message.

Business card capture: After a networking event, snap photos of business cards → your assistant extracts the details and adds them as contacts with a note about where you met.

Find connections: "Who do I know at Google?" or "I'm visiting London next week - who should I catch up with?" → search your personal network.

Call reminder: "Remind me to call Mike at 3pm" → creates a calendar event with Mike's phone number attached so you can dial straight from the reminder.

Contact updates: You receive an out-of-office saying someone left their company with a new personal email → your assistant updates their contact automatically.

(These are just examples - any workflow that needs contact lookup or management can use this.)

Setup

1. Create Google OAuth credentials
  1. Go to Google Cloud Console
  2. Create a new project (or use existing)
  3. Enable the People API
  4. Go to APIs & Services → OAuth consent screen, set up consent screen
  5. Go to APIs & Services → Credentials → Create Credentials → OAuth client ID
  6. Choose Web application
  7. Add http://localhost:3000/callback to Authorized redirect URIs
  8. Note your Client ID and Client Secret
2. Run the server
GOOGLE_CLIENT_ID='your-client-id' \
GOOGLE_CLIENT_SECRET='your-client-secret' \
MCP_TRANSPORT=http \
npm start

The server runs on http://localhost:3000 by default. Change with PORT=3001.

3. Add to your MCP client

With the server running, follow the instructions on install-mcp, which generates the right config for your MCP client (Claude Code, Claude Desktop, Cursor, Cline, VS Code, and more).

Architecture

This server acts as an OAuth proxy to Google:

graph LR
    A[MCP client] <--> B[google-contacts-mcp] <--> C[Google OAuth/API]
  1. Server advertises itself as an OAuth authorization server via /.well-known/oauth-authorization-server
  2. /register returns the Google OAuth client credentials
  3. /authorize redirects to Google, encoding the client's callback URL in state
  4. /callback receives the code from Google and forwards to the client's callback
  5. /token proxies token requests to Google, injecting client credentials
  6. /mcp handles MCP requests, using the bearer token to call People API

The server holds no tokens or state - it just proxies OAuth to Google.
