Redis MCP

Instructions

Implementation Reference

• src/services/mcpService.ts:956-968 (handler)

  The main handler function for the 'hash_get' tool. Ensures Redis connection, retrieves the hash field value using redisService.hget(key, field), and returns the result as formatted JSON text content.

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

• src/services/mcpService.ts:224-235 (schema)

  The input schema definition for the 'hash_get' tool, registered in the ListTools response. Requires 'key' and 'field' as strings.

  {
    name: 'hash_get',
    description: '获取哈希字段',
    inputSchema: {
      type: 'object',
      properties: {
        key: { type: 'string', description: '哈希键名' },
        field: { type: 'string', description: '字段名' }
      },
      required: ['key', 'field']
    }
  },

• src/services/mcpService.ts:650-651 (registration)

  Registration/dispatch in the CallToolRequestSchema handler switch statement, routing calls to the handleHashGet method.

  case 'hash_get':
    return await this.handleHashGet(args);
