Implementation Reference

• src/handlers/users-groups-handlers.ts:112-125 (handler)

  The handler function that implements the core logic for the 'gitlab_add_project_member' tool. It validates required parameters (project_id, user_id, access_level) and calls the underlying usersGroupsManager to add the member.

  export const addProjectMember: ToolHandler = async (params, context) => {
    const { project_id, user_id, access_level, expires_at } = params.arguments || {};
    if (!project_id || !user_id || !access_level) {
      throw new McpError(ErrorCode.InvalidParams, 'project_id, user_id, and access_level are required');
    }
    
    const data = await context.usersGroupsManager.addProjectMember(
      project_id as string | number,
      user_id as number,
      access_level as number,
      expires_at as string | undefined
    );
    return formatResponse(data);
  }; 

• src/utils/tools-data.ts:831-853 (schema)

  The input schema definition for the 'gitlab_add_project_member' tool, specifying parameters like project_id, user_id, and access_level with types, descriptions, and required fields.

  {
    name: 'gitlab_add_project_member',
    description: 'Add a user to a project',
    inputSchema: {
      type: 'object',
      properties: {
        project_id: {
          type: 'string',
          description: 'The ID or URL-encoded path of the project'
        },
        user_id: {
          type: 'number',
          description: 'The ID of the user'
        },
        access_level: {
          type: 'number',
          description: 'Access level (10=Guest, 20=Reporter, 30=Developer, 40=Maintainer, 50=Owner)',
          enum: [10, 20, 30, 40, 50]
        }
      },
      required: ['project_id', 'user_id', 'access_level']
    }
  }

• src/utils/tool-registry.ts:70-70 (registration)

  Registration of the 'gitlab_add_project_member' tool in the central tool registry, mapping the tool name to its handler function usersGroupsHandlers.addProjectMember.

  gitlab_add_project_member: usersGroupsHandlers.addProjectMember
