mcp-use + EVC 授权示例

这个独立示例将 Bolyra External Verifier Contract v1 主机边界放在现有 mcp-use TypeScript 中间件接缝之后。网关代理 vault_echo，启动一个单次外部验证器，验证其封闭的判定信封，并且仅在 allow 后才调用 next()。

运行

npm install
npm test
npm run dev

打开打印的 URL 以使用内置的 mcp-use Inspector。调用 vault_echo，参数如下：

{
  "message": "hello",
  "bundle": "demo-valid-bundle",
  "agentName": "research-bot",
  "model": "demo-model"
}

将 bundle 改为任何其他值，即可看到外部验证器在上游服务器运行之前拒绝该调用。

主机适配器演示了重要的 EVC 机制：stdin 上的一个请求、stdout 上的一个有界判定、超时和进程失败处理、严格的判定形状、先预留后分发的 nonce 处理，以及故障关闭行为。该验证器特意是一个极小的外部类演示，而不是 Bolyra 的 ZK 验证器。

EVC 是一个独立的第三方合约，不属于 MCP 或 mcp-use 的一部分。
