What is Attio MCP Server?

Attio MCP Server is a Model Context Protocol (MCP) server that provides complete coverage of the Attio CRM surface. It enables AI assistants like Claude and ChatGPT to interact with an entire Attio workspace through natural language—managing deals, tasks, lists, people, companies, records, and notes without raw API calls.

How to use Attio MCP Server?

Install the npm package (attio-mcp), configure it with your Attio API key, and use it with any MCP‑compatible client (e.g., Claude Desktop). For ChatGPT Pro/Plus access, deploy a self‑hosted Cloudflare Worker. Pre‑built prompts and Claude skills are available to speed up common workflows.
