Implementation Reference

• operations/pulls.ts:163-177 (handler)

  The core handler function that executes the create_pull_request tool by making a POST request to the GitHub API to create a pull request.

  export async function createPullRequest(
    params: z.infer<typeof CreatePullRequestSchema>
  ): Promise<z.infer<typeof GitHubPullRequestSchema>> {
    const { owner, repo, ...options } = CreatePullRequestSchema.parse(params);
  
    const response = await githubRequest(
      `https://api.github.com/repos/${owner}/${repo}/pulls`,
      {
        method: "POST",
        body: options,
      }
    );
  
    return GitHubPullRequestSchema.parse(response);
  }

• operations/pulls.ts:79-88 (schema)

  Zod schema defining the input parameters for the create_pull_request tool, used for validation.

  export const CreatePullRequestSchema = z.object({
    owner: z.string().describe("Repository owner (username or organization)"),
    repo: z.string().describe("Repository name"),
    title: z.string().describe("Pull request title"),
    body: z.string().optional().describe("Pull request body/description"),
    head: z.string().describe("The name of the branch where your changes are implemented"),
    base: z.string().describe("The name of the branch you want the changes pulled into"),
    draft: z.boolean().optional().describe("Whether to create the pull request as a draft"),
    maintainer_can_modify: z.boolean().optional().describe("Whether maintainers can modify the pull request")
  });

• index.ts:103-107 (registration)

  Registration of the create_pull_request tool in the list returned by ListToolsRequestHandler, including name, description, and input schema reference.

  {
    name: "create_pull_request",
    description: "Create a new pull request in a GitHub repository",
    inputSchema: zodToJsonSchema(pulls.CreatePullRequestSchema),
  },

• index.ts:276-282 (handler)

  Dispatch handler in the main CallToolRequestHandler switch that parses arguments and delegates to the pulls.createPullRequest implementation.

  case "create_pull_request": {
    const args = pulls.CreatePullRequestSchema.parse(request.params.arguments);
    const pullRequest = await pulls.createPullRequest(args);
    return {
      content: [{ type: "text", text: JSON.stringify(pullRequest, null, 2) }],
    };
  }
