创建 Pull Request

Instructions

Implementation Reference

• src/tools/pull-request.ts:27-105 (handler)

  Main handler function that executes the PR creation logic: resolves repo context, constructs options, calls Gitea API POST /pulls, formats and returns PR details.

  /**
   * 创建 Pull Request
   */
  export async function createPullRequest(
    ctx: PullRequestToolsContext,
    args: {
      owner?: string;
      repo?: string;
      title: string;
      head: string;
      base: string;
      body?: string;
      assignee?: string;
      assignees?: string[];
      milestone?: number;
      labels?: number[];
      due_date?: string;
      token?: string;
    }
  ) {
    logger.debug({ args }, 'Creating pull request');
  
    const { owner, repo } = ctx.contextManager.resolveOwnerRepo(args.owner, args.repo);
  
    const createOptions: CreatePullRequestOptions = {
      title: args.title,
      head: args.head,
      base: args.base,
      body: args.body,
      assignee: args.assignee,
      assignees: args.assignees,
      milestone: args.milestone,
      labels: args.labels,
      due_date: args.due_date,
    };
  
    const pr = await ctx.client.post<GiteaPullRequest>(
      `/repos/${owner}/${repo}/pulls`,
      createOptions,
      args.token
    );
  
    logger.info({ owner, repo, pr: pr.number }, 'Pull request created successfully');

        milestone: pr.milestone
          ? { id: pr.milestone.id, title: pr.milestone.title }
          : null,

• src/tools-registry/pr-registry.ts:32-66 (registration)

  MCP tool registration for 'gitea_pr_create': defines tool metadata, Zod inputSchema, and thin handler wrapper that calls the core createPullRequest function.

  // gitea_pr_create - 创建 PR (智能内容生成)
  mcpServer.registerTool(
    'gitea_pr_create',
    {
      title: '创建 Pull Request',
      description: 'Create a new pull request. Use this tool for AI-assisted PR creation with smart content generation.',
      inputSchema: z.object({
        owner: z.string().optional().describe('Repository owner. Uses context if not provided'),
        repo: z.string().optional().describe('Repository name. Uses context if not provided'),
        title: z.string().min(1).describe('PR title'),
        body: z.string().optional().describe('PR body/description'),
        head: z.string().min(1).describe('Branch name to merge from'),
        base: z.string().min(1).describe('Branch name to merge into'),
        assignees: z.array(z.string()).optional().describe('Usernames to assign'),
        labels: z.array(z.number()).optional().describe('Label IDs to attach'),
        milestone: z.number().optional().describe('Milestone ID'),
        token: tokenSchema,
      }),
    },
    async (args) => {
      try {
        const result = await PullRequestTools.createPullRequest(toolsContext, args as any);
        return {
          content: [{ type: 'text' as const, text: JSON.stringify(result, null, 2) }],
        };
      } catch (error: unknown) {
        const errorMessage = error instanceof Error ? error.message : String(error);
        return {
          content: [{ type: 'text' as const, text: `Error: ${errorMessage}` }],
          isError: true,
        };
      }
    }
  );

• src/tools-registry/pr-registry.ts:38-49 (schema)

  Zod schema for input validation of gitea_pr_create tool parameters.

  inputSchema: z.object({
    owner: z.string().optional().describe('Repository owner. Uses context if not provided'),
    repo: z.string().optional().describe('Repository name. Uses context if not provided'),
    title: z.string().min(1).describe('PR title'),
    body: z.string().optional().describe('PR body/description'),
    head: z.string().min(1).describe('Branch name to merge from'),
    base: z.string().min(1).describe('Branch name to merge into'),
    assignees: z.array(z.string()).optional().describe('Usernames to assign'),
    labels: z.array(z.number()).optional().describe('Label IDs to attach'),
    milestone: z.number().optional().describe('Milestone ID'),
    token: tokenSchema,
  }),

• src/index.ts:121-121 (registration)

  Top-level call to register PR tools (including gitea_pr_create) during server initialization.

  registerPullRequestTools(mcpServer, toolContext);
