Archive MCP tools exist in Rails but are NOT registered in mcp-bridge: **Status:** Incomplete - Missing mcp-bridge registration **Tools in Rails (app/controllers/api/v1/mcp_controller.rb):** - `archive_tickets` - Batch archive multiple tickets (done/cancelled only) - `list_archived_tickets` - List archived tickets - `unarchive_ticket` - Restore archived ticket **NOT in mcp-bridge (mcp-bridge/src/tools/index.ts):** - None of the above tools are registered **Decision:** Remove singular `archive_ticket` - batch `archive_tickets` can handle single element arrays. **Permissions:** Already configured for orchestrator and planner roles **Action needed:** Register `archive_tickets`, `list_archived_tickets`, `unarchive_ticket` in mcp-bridge/src/tools/index.ts
