List self-hosted runners for a workspace

A workspace's self-hosted runners, or a repository's: its own and the workspace's that its runner group lets it use.

GET/workspaces/{workspace}/actions/runners

Each has its labels (always self-hosted, its OS and its architecture), status (online, busy or offline), the work it is doing, its version and when it was last seen. A workspace’s are seen by its owners; a repository’s need the Admin role on it.

Authentication: Required. Send an access token as Authorization: Bearer.
MCP tool: workflow with action list_runners, and the same inputs
Scope: An access token needs runners:read.
Also at: GET /repos/{owner}/{name}/actions/runners

Path parameters

Name	Type	Required	Description
`workspace`	string	Yes	Instead of repo: the workspace, for the runners its repositories share.

Example request

curl https://api.g1t.sh/workspaces/flagon-io/actions/runners \
