# Accept ownership of an organization

> The ownership_transfers.accept operation: POST /api/v1/ownership_transfers/accept in the REST API and the ownership_transfers_accept tool in the MCP server.

Accepts the offer of ownership an owner made to you: you become an owner of the whole organization
(`org_owner`), and the owner who offered it becomes an admin. You must be signed in as the member the offer is
for, with a sign-in in the last 15 minutes; the offer must still be open (7 days).

**Who can call it:** the signed-in member the offer is addressed to.
