Implementation Reference

• src/tools/zrem_tool.ts:5-40 (handler)

  ZRemTool class implements the 'zrem' tool handler, including name, description, schema, validation, and execute method that calls Redis client.zRem.

  export class ZRemTool extends RedisTool {
    name = 'zrem';
    description = 'Remove one or more members from a sorted set';
    inputSchema = {
      type: 'object',
      properties: {
        key: { type: 'string', description: 'Sorted set key' },
        members: {
          type: 'array',
          description: 'Array of members to remove',
          items: { type: 'string' }
        }
      },
      required: ['key', 'members']
    };
  
    validateArgs(args: unknown): args is ZRemArgs {
      return typeof args === 'object' && args !== null &&
        'key' in args && typeof (args as any).key === 'string' &&
        'members' in args && Array.isArray((args as any).members) &&
        (args as any).members.every((member: any) => typeof member === 'string');
    }
  
    async execute(args: unknown, client: RedisClientType): Promise<ToolResponse> {
      if (!this.validateArgs(args)) {
        return this.createErrorResponse('Invalid arguments for zrem');
      }
  
      try {
        const result = await client.zRem(args.key, args.members);
        return this.createSuccessResponse(`Removed ${result} members from the sorted set`);
      } catch (error) {
        return this.createErrorResponse(`Failed to remove members from sorted set: ${error}`);
      }
    }
  }

• src/interfaces/types.ts:65-68 (schema)

  Type definition for ZRemArgs used in zrem tool validation.
