That specific capability is exactly what `add_issue_comment_reaction` in #2732 adds.\n\n_Filed automatically as part of a reactions smoke test._","author":{"url":"https://github.com/SamMorrowDrums","@type":"Person","name":"SamMorrowDrums"},"datePublished":"2026-06-23T12:53:36.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/2758/github-mcp-server/issues/2758"}
