## What it does

This server connects an MCP client with Attio and exposes operations for finding, creating, editing, and deleting companies, people, and deals. An agent can also handle tasks, lists, records, and notes, follow relationships between CRM objects, and run batch changes.

The setup uses the remote HTTP endpoint `https://server.smithery.ai/@kesslerio/attio-mcp-server/mcp`. The project metadata lists Node.js `>=20.0.0` for local use. Its tool surface is centered on data stored in an Attio workspace.

The Smithery-hosted route is marked temporarily unavailable, so this remote configuration may fail until that service is restored. ChatGPT access uses a separate self-hosted Cloudflare Worker route.
