Redis MCP

Instructions

Implementation Reference

• src/services/mcpService.ts:939-951 (handler)

  MCP tool handler for 'hash_mset' that ensures Redis connection and delegates to RedisService.hmset

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

• src/services/mcpService.ts:201-222 (schema)

  Input schema definition for the 'hash_mset' tool in the ListTools response

  {
    name: 'hash_mset',
    description: '批量设置哈希字段',
    inputSchema: {
      type: 'object',
      properties: {
        key: { type: 'string', description: '哈希键名' },
        fieldValues: {
          type: 'array',
          items: {
            type: 'object',
            properties: {
              field: { type: 'string', description: '字段名' },
              value: { type: 'string', description: '字段值' }
            },
            required: ['field', 'value']
          },
          description: '字段值对数组'
        }
      },
      required: ['key', 'fieldValues']
    }

• src/services/mcpService.ts:648-649 (registration)

  Dispatch/registration of 'hash_mset' handler in the CallToolRequest switch statement

  case 'hash_mset':
    return await this.handleHashMset(args);

• src/services/redisService.ts:226-237 (helper)

  Core Redis HMSET implementation in RedisService that converts fieldValues array to object and calls underlying Redis client hSet

  async hmset(key: string, fieldValues: RedisHashField[]): Promise<RedisOperationResult<number>> {
    return this.executeCommand(async () => {
      if (!this.client) throw new Error('Redis client not initialized');
      
      const fields: Record<string, string> = {};
      fieldValues.forEach(fv => {
        fields[fv.field] = fv.value;
      });
      
      return await this.client.hSet(key, fields);
    });
  }
