Google Drive MCP connector not passed through to Claude Code

Summary

Google Drive connector is enabled and fully OAuth-authorized on claude.ai, but its tools never appear in Claude Code. Other Google connectors (Gmail, Google Calendar) work fine.

Details

• Gmail: mcp__claude_ai_Gmail__* tools appear and work correctly
• Google Calendar: mcp__claude_ai_Google_Calendar__* tools appear and work correctly
• Google Drive: No mcp__claude_ai_Google_Drive__* tools appear at all
• Other connectors (Linear, Notion, Slack): All pass through fine

OAuth status

Google Drive OAuth is fully granted on the Google account with both scopes:

• "See, edit, create, and delete only the specific Google Drive files you use with this app"
• "See and download all your Google Drive files"

Verified at https://myaccount.google.com/permissions — Claude/Anthropic has full Drive access.

Attempted fixes

• Toggled Google Drive connector off and on in claude.ai settings
• Disconnected and re-authorized Google Drive
• No change — tools still don't appear

Environment

• Claude Code CLI (macOS)
• All other claude.ai built-in connectors pass through correctly

Expected behavior

mcp__claude_ai_Google_Drive__* tools should appear in Claude Code, the same way Gmail and Calendar tools do.
