# Remove a collaborator

> Take away the role someone was given on a repository directly.

<div class="g1t-endpoint"><span class="g1t-method" data-method="delete">DELETE</span><code>/repos/{owner}/{name}/collaborators/{username}</code></div>

Anyone may remove their own. An outside collaborator then has no access; a member keeps the workspace's base permission (change it with [`set_base_permission`](/reference/api/access/set-base-permission/), or remove them from the workspace). Needs the Admin role, unless it is your own. People only.

Takes away a direct role. Anyone may remove their own, to leave a repository. `404` when the person has no role of their own on it. A member keeps the workspace's base permission. Sends the `repo.collaborator_removed` webhook event. See [Access and roles](/guides/access-and-roles/).

- **Authentication:** Required. Send an [access token](/reference/api/#authentication) as `Authorization: Bearer`.
- **MCP tool:** [`access`](/reference/mcp/#access) with `action` `remove_collaborator`, and the same inputs
- **Scope:** An access token needs [`access:admin`](/guides/authentication/#scopes).
