Implementation Reference

• src/services/mcpService.ts:172-186 (registration)

  Registration of the string_mget tool in the ListTools response, including name, description, and input schema.

  {
    name: 'string_mget',
    description: '批量获取键值',
    inputSchema: {
      type: 'object',
      properties: {
        keys: {
          type: 'array',
          items: { type: 'string' },
          description: '键名数组'
        }
      },
      required: ['keys']
    }
  },

• src/services/mcpService.ts:905-917 (handler)

  The main handler function for the string_mget MCP tool. Ensures Redis connection, calls RedisService.mget, and returns formatted result.

  private async handleStringMget(args: any) {
    this.ensureRedisConnection();
    const result = await this.redisService!.mget(args.keys);
    
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(result, null, 2)
        }
      ]
    };
  }

• src/services/mcpService.ts:642-643 (registration)

  Dispatch case in the CallToolRequest handler that routes string_mget calls to the specific handler.

  case 'string_mget':
    return await this.handleStringMget(args);

• src/services/redisService.ts:204-209 (helper)

  Helper method in RedisService that performs the actual MGET operation using the Redis client library.

  async mget(keys: string[]): Promise<RedisOperationResult<(string | null)[]>> {
    return this.executeCommand(async () => {
      if (!this.client) throw new Error('Redis client not initialized');
      return await this.client.mGet(keys);
    });
  }
