Update an issue

PATCH/repos/{owner}/{name}/issues/{number}

Only the fields given are changed; labels and assignees each replace the whole set. Its author may change their own issue; anyone else needs the Triage role or higher.

• Authentication: Required. Send an access token as Authorization: Bearer.
• MCP tool: update_issue, with the same inputs

Path parameters

Name	Type	Required	Description
owner	string	Yes	The workspace that owns the repository.
name	string	Yes	The repository’s name.
number	integer	Yes	The number shown after the #. Issues and pull requests share one sequence.

Body parameters

Send a JSON object. Names are snake_case, as in responses; the camelCase spelling is accepted too.

Name	Type	Required	Description
title	string	No
body	string	No
labels	array of strings	No
assignees	array of strings	No	Usernames of the people it is assigned to. Replaces the whole set; an empty list unassigns everyone. To assign it to the g1t agent, use assign_issue.
