Implementation Reference

• operations/repository.ts:51-65 (handler)

  The main handler function that forks a GitHub repository by making a POST request to the GitHub API and parsing the response.

  export async function forkRepository(
    owner: string,
    repo: string,
    organization?: string
  ) {
    const url = organization
      ? `https://api.github.com/repos/${owner}/${repo}/forks?organization=${organization}`
      : `https://api.github.com/repos/${owner}/${repo}/forks`;
  
    const response = await githubRequest(url, { method: "POST" });
    return GitHubRepositorySchema.extend({
      parent: GitHubRepositorySchema,
      source: GitHubRepositorySchema,
    }).parse(response);
  }

• operations/repository.ts:19-23 (schema)

  Zod schema defining the input parameters for the fork_repository tool: owner, repo, and optional organization.

  export const ForkRepositorySchema = z.object({
    owner: z.string().describe("Repository owner (username or organization)"),
    repo: z.string().describe("Repository name"),
    organization: z.string().optional().describe("Optional: organization to fork to (defaults to your personal account)"),
  });

• index.ts:108-112 (registration)

  Tool registration in the list of tools returned by ListToolsRequest, specifying name, description, and input schema.

  {
    name: "fork_repository",
    description: "Fork a GitHub repository to your account or specified organization",
    inputSchema: zodToJsonSchema(repository.ForkRepositorySchema),
  },

• index.ts:169-175 (registration)

  Handler case in the CallToolRequest switch statement that parses arguments, calls the forkRepository function, and returns the result.

  case "fork_repository": {
    const args = repository.ForkRepositorySchema.parse(request.params.arguments);
    const fork = await repository.forkRepository(args.owner, args.repo, args.organization);
    return {
      content: [{ type: "text", text: JSON.stringify(fork, null, 2) }],
    };
  }
