MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms

Attio Assert List Entry — Assert a list entry by parent record: if the record is already in the list, update it; otherwise add it. Idempotent upsert for list entries.
Attio Assert Record — Assert a record: find by matching attribute and update, or create if not found. The matching_attribute must be is_unique=true. For people use 'email_addresses'; for companies use 'domains'. When a person has no email, create the record with a direct upsert (no matching attribute) instead — assert requires a unique matching attribute.
Attio Create Attribute — Create a new attribute (field/column) on an object or list. Supports text, number, select, status, currency, date, and many other types.
Attio Create Comment — Create a comment on a record or reply to an existing thread. Use thread_id to reply, or record_id + object to start a new thread. Workspace members can be @mentioned by email.
Attio Create List — Create a new list (pipeline/board) in your Attio workspace. Lists contain entries that reference records. After creating, add attributes with create_attribute and records with upsert_list_entry. Requires name, api_slug, parent_object, and workspace_access.
Attio Create Note — Create a new note on a record. Notes are immutable once written; corrections require a separate replacement note. Returns the created note.
Attio Create Object — Create a new custom object type in your Attio workspace. Objects define data models (like people, companies, or custom types). After creating, add attributes with create_attribute.
Attio Create Select Option — Create a new option for a select-type attribute. Use list_select_options to see existing options first.
