Feature request: add label management (create/update/delete labels) to GitHub MCP server

[gloriouskilka]

Problem

The GitHub MCP server currently exposes label read operations (e.g. get_label) and issue labeling via issue_write, but it does not expose label management APIs. This blocks automation like bootstrapping repo-wide SDLC labels (stream/, p, state/, type/).

Why this should be supported

GitHub’s REST API supports labels management (create/update/delete labels) and organizations/maintainers commonly need to bootstrap consistent label taxonomies.

Requested MCP capabilities

• Create label (name, color, description)
• Update label (rename, recolor, description)
• Delete label
• List labels (already indirectly possible via search, but a first-class list would help)

Example use case

Repo needs to bootstrap these labels:

• stream/core-loop, stream/bench-datasets, stream/ttmetal
• p1, p2, p3, next
• type/bug, type/feature, type/chore, type/docs, type/research
• state/draft, state/to-research, state/spec-ready, state/ready, state/in-progress, state/blocked, state/in-review, state/done

Acceptance criteria

• A user can create/update/delete labels via MCP without needing gh CLI or manual UI steps.
