Attio MCP Server

Attio's official Model Context Protocol server puts an AI agent inside your CRM. It is hosted by Attio at https://mcp.attio.com/mcp: you log in with your existing Attio account over OAuth, and there is no API key to mint, rotate or leak into a config file.

Roughly 37 tools across nine areas. Records and objects — search, list, create, update and merge people, companies, deals and any custom object you have modelled. Lists — create lists, read them and update entries. Comments and notes — leave a comment on a record, or write a note that is then reachable by semantic search. Tasks — create follow-ups with deadlines linked to the right record. Meetings and calls — search meetings and call recordings by topic, not just by date. Emails — retrieve message content by metadata or by subject matter. Workspace — members, teams and identity. Reporting — aggregate reports, plus read-only SQL over your workspace data, which is gated to specific billing plans.

Why the semantic-search tools matter. Most CRM integrations give an agent keyword search and little else, which fails on the question people actually ask — "what did we tell this account about pricing?" Attio's notes, meeting and email tools search on meaning, so the agent can answer from the conversation history rather than from field values alone.

Rate limits are published, which is worth knowing before you point an autonomous agent at it: 100 reads/second, 25 writes/second, 300 searches/minute, and 2 semantic searches/second.

Installing it. In Claude and ChatGPT it is a first-party listed connector — search for Attio in the connector directory and click through the OAuth prompt. Cursor, Raycast and any other MCP client take the endpoint URL directly. Nothing is self-hosted and there is no JSON to hand-write beyond pointing a client at the URL.
