What's Wrong?
Body:
## Summary
Gmail MCP integration is connected on claude.ai but does not load in Claude Code CLI sessions.
Google Calendar MCP (gcal.mcp.claude.com) — connected identically — works fine in the same session.
## Environment
- Claude Code CLI (terminal)
- macOS
- MCP integrations connected via claude.ai account (not local ~/.claude/settings.json)
## Steps to Reproduce
- Connect both Gmail and Google Calendar integrations on claude.ai
- Open Claude Code in terminal
- Google Calendar tools are available (mcp__claude_ai_Google_Calendar__gcal_*)
- Gmail tools are not available — ToolSearch returns no Gmail-related tools
## Expected Behavior
Gmail MCP tools should load in Claude Code CLI sessions the same way Google Calendar tools do,
since both integrations are connected via the same claude.ai account.
## Actual Behavior
Gmail MCP tools are absent from the session. mcpServers in ~/.claude/settings.json is empty {},
confirming the integrations are being injected via the cloud account — but only Calendar comes through, not Gmail.
## Workaround
None found. Manually adding via settings.json is not viable as the hosted MCP server config is not publicly
documented.
