Implementation Reference

• operations/pulls.ts:277-286 (handler)

  The main handler function that executes the tool logic by calling the GitHub API to fetch reviews for a specific pull request and parsing the response.
  export async function getPullRequestReviews( owner: string, repo: string, pullNumber: number ): Promise<z.infer<typeof PullRequestReviewSchema>[]> { const response = await githubRequest( `https://api.github.com/repos/${owner}/${repo}/pulls/${pullNumber}/reviews` ); return z.array(PullRequestReviewSchema).parse(response); }
• operations/pulls.ts:156-160 (schema)

  Input schema validation using Zod for the get_pull_request_reviews tool parameters.
  export const GetPullRequestReviewsSchema = z.object({ owner: z.string().describe("Repository owner (username or organization)"), repo: z.string().describe("Repository name"), pull_number: z.number().describe("Pull request number") });
• index.ts:195-199 (registration)

  Tool registration in the list of available tools, including name, description, and input schema reference.
  { name: "get_pull_request_reviews", description: "Get the reviews on a pull request", inputSchema: zodToJsonSchema(pulls.GetPullRequestReviewsSchema) },
• index.ts:566-576 (handler)

  Dispatch handler in the main switch statement that parses arguments, calls the pulls.getPullRequestReviews function, and formats the response.
  case "get_pull_request_reviews": { const args = pulls.GetPullRequestReviewsSchema.parse(request.params.arguments); const reviews = await pulls.getPullRequestReviews( args.owner, args.repo, args.pull_number ); return { content: [{ type: "text", text: JSON.stringify(reviews, null, 2) }], }; }
