kesslerio-attio-mcp-server — Claude Code MCP server
Connects an AI agent to Attio so it can work with contacts, companies, deals, and tasks. Useful when CRM actions should run through natural-language requests.
claude mcp add --transport http kesslerio-attio-mcp-server https://server.smithery.ai/@kesslerio/attio-mcp-server/mcpWhat kesslerio-attio-mcp-server 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.
What it helps with
- search for companies and people by several conditions
- create or update deals in Attio
- track tasks with multiple assignees
- manage lists and their entries
- trace links between companies, people, and deals
Example prompts for the agent
- Find Attio companies matching these conditions and add them to a list.
- Update the deal stage and add a short note about the latest contact.
- Show the people linked to this company and create an Attio task for them.
