Redis MCP

Instructions

Implementation Reference

• src/services/mcpService.ts:1262-1274 (handler)

  MCP tool handler for 'key_type': ensures Redis connection, calls RedisService.type(key), and formats result as MCP content response.

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

• src/services/mcpService.ts:537-547 (registration)

  Tool registration in ListTools response: defines name 'key_type', description, and input schema requiring 'key' parameter.

  {
    name: 'key_type',
    description: '获取键类型',
    inputSchema: {
      type: 'object',
      properties: {
        key: { type: 'string', description: '键名' }
      },
      required: ['key']
    }
  },

• src/services/mcpService.ts:694-695 (registration)

  Dispatch registration in CallToolRequestSchema switch statement: routes 'key_type' calls to handleKeyType method.

  case 'key_type':
    return await this.handleKeyType(args);

• src/services/redisService.ts:505-510 (helper)

  RedisService helper method implementing the core Redis TYPE key command via the redis client.

  async type(key: string): Promise<RedisOperationResult<string>> {
    return this.executeCommand(async () => {
      if (!this.client) throw new Error('Redis client not initialized');
      return await this.client.type(key);
    });
  }
