Redis MCP

Instructions

Implementation Reference

• src/services/mcpService.ts:990-1002 (handler)

  The main handler function for the 'hash_del' tool. It ensures Redis connection, calls hdel on RedisService with key and fields, and returns the result as MCP content.

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

• src/services/mcpService.ts:247-268 (registration)

  Registration of the 'hash_del' tool in the ListTools response, defining name, description, and input schema.

  {
    name: 'hash_del',
    description: '删除哈希字段',
    inputSchema: {
      type: 'object',
      properties: {
        key: { type: 'string', description: '哈希键名' },
        fields: {
          oneOf: [
            { type: 'string', description: '字段名' },
            { 
              type: 'array', 
              items: { type: 'string' },
              description: '字段名数组'
            }
          ],
          description: '要删除的字段名或字段名数组'
        }
      },
      required: ['key', 'fields']
    }
  },

• src/services/mcpService.ts:654-655 (handler)

  Dispatch case in the main CallToolRequest handler that routes 'hash_del' calls to the specific handleHashDel method.

  case 'hash_del':
    return await this.handleHashDel(args);
