Mark a repository's notifications read

Mark every thread in your inbox read, or every thread about one repository.

PUT/repos/{owner}/{name}/notifications

Threads whose latest activity came after last_read_at (now, when left out) stay unread, so nothing that arrived while you looked is lost. With read false they are marked unread instead. Returns how many changed.

Authentication: Required. Send an access token as Authorization: Bearer.
MCP tool: notifications with action mark_all_read, and the same inputs
Scope: An access token needs notifications:write.
Also at: PUT /notifications

Errors

A failed request answers with one of these statuses and a body like {"error": {"code": "not_found", "message": "Repository not found."}}. See errors.

Status	Code	When
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 an agent token outside its repository.
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.
