Implementation Reference

• src/index.ts:926-942 (registration)

  Tool registration and input schema definition for 'gitlab_close_issue'

  {
    name: 'gitlab_close_issue',
    description: 'Closes a GitLab issue.',
    inputSchema: {
      type: 'object',
      properties: {
        projectPath: {
          type: 'string',
          description: 'The path of the GitLab project.',
        },
        issueIid: {
          type: 'number',
          description: 'The internal ID of the issue.',
        },
      },
      required: ['projectPath', 'issueIid'],
    },

• src/index.ts:2034-2048 (handler)

  MCP tool handler that dispatches the call to GitLabService.closeIssue

  case 'gitlab_close_issue': {
    if (!gitlabService) {
      throw new Error('GitLab service is not initialized.');
    }
    const { projectPath, issueIid } = args as { projectPath: string; issueIid: number };
    const result = await gitlabService.closeIssue(projectPath, issueIid);
    return {
      content: [
        {
          type: 'text',
          text: `Issue closed successfully: ${JSON.stringify(result, null, 2)}`,
        },
      ],
    };
  }

• src/gitlab.service.ts:701-704 (handler)

  GitLabService.closeIssue method implementing the core tool logic by calling updateIssue

  // New tool: Close Issue
  async closeIssue(projectPath: string, issueIid: number): Promise<any> {
    return this.updateIssue(projectPath, issueIid, { state: 'close' });
  }

• src/gitlab.service.ts:678-698 (helper)

  Generic updateIssue helper method that sends PUT request to GitLab API, used by closeIssue to set state_event to 'close'

  async updateIssue(projectPath: string, issueIid: number, updates: {
    title?: string;
    description?: string;
    labels?: string[];
    assigneeIds?: number[];
    state?: 'close' | 'reopen';
  }): Promise<any> {
    const encodedProjectPath = encodeURIComponent(projectPath);
    const body: any = {};
    
    if (updates.title) body.title = updates.title;
    if (updates.description) body.description = updates.description;
    if (updates.labels) body.labels = updates.labels.join(',');
    if (updates.assigneeIds) body.assignee_ids = updates.assigneeIds;
    if (updates.state) body.state_event = updates.state;
    
    return this.callGitLabApi<any>(
      `projects/${encodedProjectPath}/issues/${issueIid}`,
      'PUT',
      body,
    );
