Commit comments

Comment on a commit

Comment on a commit, as a whole or, with path and line, on one line of a file the commit changed (a line of the file as the commit left it).

POST/repos/{owner}/{name}/commits/{sha}/comments

Anyone who can read the repository may, unless it has turned commit comments off (allow_commit_comments on update_repo_settings). The commit’s author and anyone mentioned are notified. Publishes commit_comment.created.

line needs path, a file the commit changed, and counts lines of that file as the commit left it. A repository with allow_commit_comments off answers 403; a commit it does not have, 404. See Commit comments.

Authentication: Required. Send an access token as Authorization: Bearer.
MCP tool: repository with action comment_on_commit, and the same inputs
Scope: An access token needs issues:write.

401	`unauthenticated`	A token is required, or the one sent is not valid.
403	`forbidden`	The token is valid but not allowed to do this, such as a member-only change, or a token without the scope it needs.
404	`not_found`	It does not exist, or you cannot see it.
409	`conflict`	The request conflicts with the current state.
422	`invalid`	The input is not valid. `message` says which field and why.
