{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"`label_write` delete is missing `DestructiveHint: true` annotation","articleBody":"### Describe the bug\n\nThe `label_write` tool (`pkg/github/labels.go`) supports a `delete` method that deletes a label at the repository level via the `deleteLabel` GraphQL mutation. This permanently removes the label and all of its associations from every issue and PR in the repository.\n\nHowever, the tool's annotations only set `ReadOnlyHint: false`. It does **not** set `DestructiveHint: true`. As a result, MCP clients receive no destructive-operation signal for what is arguably the most destructive label operation available, and may not surface an appropriate confirmation prompt before executing it.\n\n### Expected behavior\n\n`label_write` should be annotated with `DestructiveHint: true` (at minimum when `method` is `delete`), so MCP clients can warn the user before a repository-wide label deletion.\n\n### Precedent in the codebase\n\nThe annotation discipline already exists elsewhere in the same package:\n- `remove_sub_issue` correctly sets `DestructiveHint: jsonschema.Ptr(true)`\n- The non-destructive issue label update (`update_issue_labels`) sets `DestructiveHint: jsonschema.Ptr(false)`\n\n`label_write` delete simply appears to have been missed.\n\n### Impact\n\nAn agent intending a minor change can trigger a repository-wide label deletion with no destructive-operation hint. Because deleting a label removes it from all issues/PRs, the associations cannot be automatically restored even if the label is recreated with the same name.\n\n### Version\n\nVerified against the open-source `github-mcp-server` v1.4.0 (latest release) and the hosted GitHub Copilot MCP endpoint at `api.githubcopilot.com/mcp/` (as of 2026-06-18). The missing annotation has been present since `label_write` was introduced (ref #312).","author":{"url":"https://github.com/pritesh-lahoti","@type":"Person","name":"pritesh-lahoti"},"datePublished":"2026-06-17T17:47:18.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/2723/github-mcp-server/issues/2723"}
