Instructions

Implementation Reference

• src/api/labels.ts:92-104 (handler)

  The actual implementation of the deleteLabel function which performs the API call.

  export async function deleteLabel(projectId: string, name: string): Promise<void> {
    if (!projectId?.trim()) {
      throw new Error("Project ID is required");
    }
    if (!name?.trim()) {
      throw new Error("Label name is required");
    }
  
    const encodedName = encodeURIComponent(name);
    const endpoint = `/projects/${encodeProjectId(projectId)}/labels/${encodedName}`;
  
    await gitlabDelete(endpoint);
  }

• src/schemas.ts:307-310 (schema)

  Input validation schema for the delete_label tool.

  export const DeleteLabelSchema = z.object({
    project_id: z.string(),
    name: z.string()
  });

• src/server.ts:319-322 (registration)

  The tool registration/handling logic within the main server switch statement.

  case "delete_label": {
    const args = DeleteLabelSchema.parse(request.params.arguments);
    await api.deleteLabel(args.project_id, args.name);
    return { content: [{ type: "text", text: JSON.stringify({ success: true }, null, 2) }] };
