What this connection enables

Attio lets your workflows read, create, and update records, notes, and tasks in your Attio CRM. It can act as both a data source and a delivery target — for example, enriching a record from web research or filing a summary as a note.

​
A first-party MCP integration

Attio is CelerFlow’s first first-party MCP integration. Unlike the Composio-brokered apps, CelerFlow runs the OAuth and Model Context Protocol connection to Attio directly. From your side the experience is the same — connect once from Apps — but under the hood the connection is stored with source = first_party_mcp rather than composio. See Connections for the two-source model.

​
Connect it

From Apps, click Connect Attio. A popup runs Attio’s OAuth consent (PKCE) and the card flips to Connected once the grant is authorized. The connection is team-scoped and shared with your teammates.

​
Scopes and permissions

The grant covers MCP access to your Attio workspace — reading and writing records, notes, and tasks. CelerFlow refreshes the access token automatically as needed.
