Attio MCP Server

Attio's official hosted MCP server for querying and updating records, lists, and notes via AI agents.

Overview

Attio ships its own hosted MCP server, OAuth-based and secure by design so read operations are auto-approved while writes require explicit confirmation. It exposes the CRM's core objects: People, Companies, Deals, Tasks, Lists, and Notes. A well-known community alternative, kesslerio/attio-mcp-server, covers a similarly full surface for teams that want a self-hosted option.

Best for: Safe agent access to Attio: reads and writes with confirmation guardrails built in, for teams already running the CRM.
