Sessions

List sessions

A repository's sessions, most recently heard from first, up to 100: state active (heard from in the last 15 minutes), idle or ended; issue or pull for those on one, attached or tied to it any other way; path for those that touched a file (or any under a folder ending in /).

GET/repos/{owner}/{name}/sessions

Subagents are left out unless subagents is true, which lists each tree whole. Each says how many subagents it started. Anyone who can read the repository may.

Authentication: Optional. Public data can be read without a token; send one to see what is private.
MCP tool: session with action list, and the same inputs
Scope: An access token needs pull_requests:read.

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.
422	`invalid`	The input is not valid. `message` says which field and why.
