Google Calendar + Gmail Integration

Google Calendar and Gmail are connected via MCP servers, giving Claude Code native access to your calendar and inbox. The @clawdia agent uses these for morning briefings, email triage, scheduling, and follow-up tracking.

MCP Setup

Both services use separate MCP servers. If you selected Google integrations during make setup, they are already configured in .claude/settings.json.

Google Calendar MCP

{
  "mcpServers": {
    "google-calendar": {
      "command": "npx",
      "args": ["-y", "@anthropic-ai/google-calendar-mcp"],
      "env": {
        "GOOGLE_OAUTH_CREDENTIALS": "<path-to-credentials.json>",
        "GOOGLE_OAUTH_TOKEN": "<path-to-token.json>"
      }
    }
  }
}

Gmail MCP

{
  "mcpServers": {
    "gmail": {
      "command": "npx",
      "args": ["-y", "@anthropic-ai/gmail-mcp"],
      "env": {
        "GOOGLE_OAUTH_CREDENTIALS": "<path-to-credentials.json>",
        "GOOGLE_OAUTH_TOKEN": "<path-to-token.json>"
      }
    }
  }
}

Google Cloud Setup

Both MCPs share the same OAuth credentials.

1. Create a Google Cloud Project

Go to console.cloud.google.com
Create a new project (or use an existing one)
Enable the Google Calendar API and Gmail API from the API Library

2. Create OAuth Credentials

Go to APIs & Services > Credentials
Click Create Credentials > OAuth client ID
Application type: Desktop app
Download the JSON file and save it (e.g., ~/.config/google/credentials.json)

3. Authorize on First Run

The first time Claude Code invokes a Google MCP tool, it opens a browser window for OAuth consent. Sign in with your Google account and grant the requested permissions. The token is saved to the path specified in GOOGLE_OAUTH_TOKEN.

Calendar Operations

The Google Calendar MCP provides these tools:

Tool	What it does
`gcal_list_events`	List upcoming events with date range filter
`gcal_get_event`	Get details of a specific event
`gcal_create_event`	Create a new calendar event
`gcal_update_event`	Update an existing event
`gcal_delete_event`	Delete an event
`gcal_find_my_free_time`	Find available time slots
`gcal_find_meeting_times`	Find times when multiple people are free
`gcal_list_calendars`	List all calendars
`gcal_respond_to_event`	Accept, decline, or tentatively accept

Example Usage in Claude Code

> What's on my calendar today?
> Find a 30-minute slot tomorrow afternoon
> Create a meeting with Danilo on Friday at 2pm about sprint planning
> Accept the invitation from Marcelo

Gmail Operations

The Gmail MCP provides these tools:

Tool	What it does
`gmail_search_messages`	Search inbox with Gmail query syntax
`gmail_read_message`	Read a specific email
`gmail_read_thread`	Read an entire email thread
`gmail_create_draft`	Create a draft reply or new email
`gmail_list_drafts`	List existing drafts
`gmail_list_labels`	List all labels/folders
`gmail_get_profile`	Get account info

Example Usage in Claude Code

> Show me unread emails from today
> Read the latest email from Samara
> Draft a reply to the HostGator thread
> Search for emails about "invoice" from last week

Email Triage

The gog-email-triage skill uses Gmail MCP to:

Fetch unread emails from the last N hours
Classify each by urgency (P0-P3) and category
Propose actions: reply, archive, create task, schedule follow-up

Run it manually or let the scheduler handle it:

make triage    # runs daily at 07:15 BRT

Sending Emails

Email sending requires explicit confirmation. The gog-email-send skill asks for the exact string YES, SEND before executing. All sends are logged to the audit trail.

Skills That Use Google

Skill	Service	What it does
`gog-calendar`	Calendar	View agenda, find slots, create events
`gog-email-triage`	Gmail	Triage and prioritize inbox
`gog-email-draft`	Gmail	Draft replies and new messages
`gog-email-send`	Gmail	Send with explicit confirmation
`gog-followups`	Gmail	Track stale threads, generate reminders
`gog-tasks`	Tasks	Create and manage tasks from emails
`prod-good-morning`	Both	Morning briefing with agenda + inbox summary

Troubleshooting

“Token expired” — Delete the token file and restart Claude Code. It will re-prompt for OAuth consent. “Access denied” — Ensure both Calendar API and Gmail API are enabled in your Google Cloud project. “MCP server not found” — Run npx -y @anthropic-ai/google-calendar-mcp manually to verify it installs correctly. Requires Node.js 18+.
