Attio MCP

Attio is a CRM whose data model is deliberately open-ended: standard objects such as companies, people, and deals sit alongside custom objects a team defines, each with its own attributes, and records are grouped into lists that carry their own per-entry fields. Its MCP server exposes that structure over the Model Context Protocol, which lets an assistant work usefully with a workspace whose shape it has never seen before. The first thing an agent can do is read the schema: which objects exist, what attributes each carries, and which lists are configured. From there it can search and retrieve records across those objects, create new ones and update attribute values, add records to a list or read the entries already there, and read and write the notes and tasks attached to a record. Because the schema is discoverable rather than assumed, the same server behaves correctly on a workspace that tracks investors and one that tracks recruiting candidates. The connection is authenticated per workspace with scoped access, so a token can be limited to reading rather than writing. It suits teams that treat Attio as the operating record for customers or pipeline and want an agent to answer questions from it, enrich records after a meeting, or keep list membership current. The discoverable schema is the practical difference: an agent gets the workspace's real vocabulary instead of generic CRM field names it would otherwise have to guess.
