Gmail

This is a solid OAuth-based Gmail integration that handles the full spectrum of email operations: sending, searching, drafting, and organizing messages with label support. The standout feature is thread retrieval with automatic Google Groups permalinks, which is genuinely useful if you're debugging mailing list discussions. It uses a markdown-with-frontmatter approach for composing emails, which feels natural for Claude's workflow. The check command is well thought out for verifying your OAuth setup before you waste time troubleshooting. Setup requires the usual Google Cloud OAuth dance with client credentials, but the documentation links to full guides. The query syntax mirrors Gmail's native search, so if you know "is:unread from:someone@example.com" already, you're good to go.
