FetchSandbox
官网称 FetchSandbox 做软件变更验证：团队每天发布代码，CI 变绿不代表系统行为依然正确；它围绕“不变量”（如重试不得重复扣款、查询不得丢失记录）做验证——在隔离环境中注入超时、重试、并发等故障，观察实际行为并输出可检查的证据收据；免费集成引擎今日即可通过 MCP 与网页应用使用，支持 Claude Code、Cursor 等 agent；团队版以共建试点形式提供；明确不在生产系统做故障测试；一次通过不代表覆盖所有生产故障。

Capabilities and conditions
- 官网称其验证软件变更：CI 变绿不代表行为依然正确；围绕不变量（如重试不得重复生效）定义规则；在受控故障下观察实际行为，输出可检查的证据收据而非“一切正常”的断言。 Source ↗
- 官网称其补充而非替代现有 CI 与测试；面向工程团队、平台负责人与 agent 工作流构建者；免费集成引擎今日即可通过 MCP 试用。 Source ↗
- 官网称通过 MCP 接入客户端后可让 agent 直接测试集成；集成引擎今日即可通过 MCP 与网页应用使用；共享收据的证据经脱敏处理，隐藏凭证与敏感数据。 Source ↗
- 官网称免费集成引擎今日可用；团队服务以共建验证试点的形式提供（围绕关键行为约定环境与验收标准）；未公布团队版价格。 Source ↗
- 官网称故障测试从隔离环境开始，不在生产系统做；收据结论仅适用于已记录的版本、场景与观测窗口；一次通过不保证覆盖所有生产故障。 Source ↗
