Redis MCP

Instructions

Implementation Reference

• src/services/mcpService.ts:1211-1223 (handler)

  The main handler function for the 'key_expire' MCP tool. It ensures Redis connection and calls RedisService.expire to set key expiration time.

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

• src/services/mcpService.ts:503-514 (schema)

  The input schema definition for the 'key_expire' tool, registered in the ListTools response.

  {
    name: 'key_expire',
    description: '设置键过期时间',
    inputSchema: {
      type: 'object',
      properties: {
        key: { type: 'string', description: '键名' },
        seconds: { type: 'number', description: '过期时间（秒）' }
      },
      required: ['key', 'seconds']
    }
  },

• src/services/mcpService.ts:688-689 (registration)

  The dispatch/registration case in the CallToolRequestHandler switch statement that routes 'key_expire' calls to the handler.

  case 'key_expire':
    return await this.handleKeyExpire(args);

• src/services/redisService.ts:474-480 (helper)

  Supporting utility method in RedisService that implements the actual Redis EXPIRE command via the redis client.

  async expire(key: string, seconds: number): Promise<RedisOperationResult<boolean>> {
    return this.executeCommand(async () => {
      if (!this.client) throw new Error('Redis client not initialized');
      const result = await this.client.expire(key, seconds);
      return Boolean(result);
    });
  }
