Implementation Reference

• src/index.js:271-276 (handler)

  The handler function for vk_groups_get_by_id - processes the tool call arguments, calls the VKClient.groupsGetById method with group_ids and fields parameters, and returns the result as JSON

  case 'vk_groups_get_by_id':
    result = await vk.groupsGetById({
      group_ids: args.group_ids,
      fields: args.fields || 'description,members_count',
    });
    break;

• src/index.js:158-168 (schema)

  Tool schema definition for vk_groups_get_by_id - defines the input schema with group_ids (comma-separated IDs) and optional fields parameters for community information

  {
    name: 'vk_groups_get_by_id',
    description: 'Get community info by ID or short name',
    inputSchema: {
      type: 'object',
      properties: {
        group_ids: { type: 'string', description: 'Comma-separated group IDs' },
        fields: { type: 'string', description: 'Community fields' },
      },
    },
  },

• src/index.js:330-330 (registration)

  Tool registration - the ListToolsRequestSchema handler returns all tools including vk_groups_get_by_id to the MCP server

  server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools }));

• src/index.js:61-61 (helper)

  VKClient helper method - groupsGetById wraps the VK API 'groups.getById' method call with authentication and version parameters

  groupsGetById(params) { return this.call('groups.getById', params); }
