Skills
This plugin bundles an /unsubscribe skill for conversational email triage:
/unsubscribe # List newsletters and prompt for action
/unsubscribe list # Show all subscription candidates
/unsubscribe info <id> # Inspect unsubscribe options for a message
/unsubscribe unsub <id> # Unsubscribe from a specific message
/unsubscribe status # View attempt log
The skill orchestrates the MCP tools with safety checks — it always confirms before executing, and logs all attempts.
How It Works
Most marketing emails include a List-Unsubscribe header (required by Gmail since 2024 for bulk senders). This server parses that header and executes the unsubscribe automatically:
- RFC 8058 One-Click POST (~70-80% of senders) — sends
List-Unsubscribe=One-Clickto the HTTPS URL - HTTPS GET fallback (~10-15%) — follows the unsubscribe URL
- Mailto fallback (~10-15%) — sends an email to the unsubscribe address via Gmail API
