Kesslerio Attio Mcp Server

This connects Claude directly to your Attio CRM workspace through a universal tools architecture that handles companies, people, deals, tasks, lists, and notes. Instead of 40+ resource-specific tools, it consolidates operations into 19 universal actions with scoped write tools for high-frequency updates. You get full CRUD operations, batch processing, advanced filtering with AND/OR logic, and relationship navigation across all record types. Ships with Claude skills that teach your workspace's exact field names to prevent common errors. Best reached for when you want to query pipeline data, bulk update records, or automate CRM workflows through natural language without clicking through Attio's UI. ChatGPT integration works through a self-hosted Cloudflare Worker with OAuth.
