Implementation Reference

• src/services/mcpService.ts:1228-1239 (handler)

  The handler function that implements the key_ttl MCP tool. It ensures a Redis connection exists and calls the RedisService.ttl method with the provided key argument, returning the result as formatted text content.

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

• src/services/mcpService.ts:518-524 (schema)

  Input schema definition for the key_ttl tool, specifying that a 'key' string parameter is required.

  inputSchema: {
    type: 'object',
    properties: {
      key: { type: 'string', description: '键名' }
    },
    required: ['key']
  }

• src/services/mcpService.ts:515-525 (registration)

  Tool registration in the ListTools response, defining name, description, and input schema for key_ttl.

  {
    name: 'key_ttl',
    description: '获取键过期时间',
    inputSchema: {
      type: 'object',
      properties: {
        key: { type: 'string', description: '键名' }
      },
      required: ['key']
    }
  },

• src/services/mcpService.ts:690-691 (registration)

  Dispatcher case in CallToolRequest handler that routes key_ttl calls to the handleKeyTtl method.

    return await this.handleKeyTtl(args);
