# Attio

The CRM for revenue teams, with records, lists, notes and tasks an agent can read and write.

Attio is a CRM for revenue teams. Its hosted MCP server signs in as an Attio
user with OAuth, and its REST API takes a workspace access token that an
admin creates under Workspace settings, Developers. Both read and write
people, companies, deals and custom objects, list entries, notes and tasks.

## Tools

- tool:attio/create-note — Create a note: Adds a note with a title and plaintext or markdown content to a person, company, deal or other record.
- tool:attio/create-record — Create a record: Creates a person, company, deal or custom-object record, and fails if a unique attribute such as a domain or email address is already taken.
- tool:attio/list-records — List records: Returns the records of one object, such as people, companies or deals, filtered and sorted by their attribute values.
- tool:attio/update-record — Update a record: Updates the given attributes of one record by its record id, adding to multiselect values instead of replacing them.
- tool:attio/upsert-record — Upsert a record: Updates the record whose matching attribute, such as a company's domain or a person's email, has the given value, or creates the record if none does.
