Instructions

Implementation Reference

• src/services/mcpService.ts:922-934 (handler)

  The MCP tool handler for 'hash_set' that ensures Redis connection and executes hset command via RedisService.

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

• src/services/mcpService.ts:188-199 (schema)

  Tool definition in listTools response, including name, description, and input schema for validation.

  {
    name: 'hash_set',
    description: '设置哈希字段',
    inputSchema: {
      type: 'object',
      properties: {
        key: { type: 'string', description: '哈希键名' },
        field: { type: 'string', description: '字段名' },
        value: { type: 'string', description: '字段值' }
      },
      required: ['key', 'field', 'value']
    }

• src/services/mcpService.ts:646-647 (registration)

  Dispatch case in CallToolRequestSchema handler that routes 'hash_set' calls to the handler function.

  case 'hash_set':
    return await this.handleHashSet(args);
