agent-platform-api
MCP server for the Agent Platform API, enabling management of sandbox environments through MCP protocol. Exposes tools to interact with sandbox lifecycle operations such as start, stop, and status checks.

agent-platform-api
后端仓库:NestJS 11 + Node 22 + TypeScript strict + pnpm workspaces(modular monolith)+ zod 单源 + Drizzle/better-sqlite3 + MCP/REST 双协议。
结构与分层的权威文档:docs/backend/01(本仓在 monorepo 的 api/ 子目录内实现)。
快速开始
pnpm install
pnpm db:generate # 从 schema 生成 drizzle 迁移(首次已提交在 ./drizzle)
pnpm build # tsc -b 全量构建(project references)
pnpm start # node apps/api/dist/main.js
# → GET http://127.0.0.1:3000/api/health {"status":"ok"}
# → http://127.0.0.1:3000/openapi.json 完整 OpenAPI
# → http://127.0.0.1:3000/docs Swagger UI
默认只监听 127.0.0.1(shared/11 §3,审计 P0-3)。改 HOST=0.0.0.0 会在启动日志打醒目告警。
工作区结构
api/
├── packages/
│ ├── shared-kernel/ # Clock / IdGenerator / UnitOfWork(同步) / EventBus 端口 + AggregateRoot + branded ID
│ ├── contracts/ # zod 单源(schemas/)+ 统一错误 envelope + registry tokens

其余六个上下文(project / runtime / image / credential / terminal / automation)遵循与
sandbox完全相同的四层形态(docs/backend/01 §2),按同一套 harness 增量落地。本次脚手架只把sandbox做成可编译运行的最小闭环。
DDD 四层与依赖规则(eslint-plugin-boundaries 强制)
interface ──▶ application ──▶ domain ◀── infrastructure(实现端口)
└────────▶ contracts ◀──────────┘
| 层 | 允许依赖 | 关键禁令 |
|---|---|---|
| domain | domain、shared-kernel | 任何三方 IO 库、框架代码、contracts |
| application | domain、contracts、shared-kernel | 直接 import infrastructure 具体实现(走端口) |
| infrastructure | domain、contracts、shared-kernel、三方库 | — |
| interface | application、contracts | 触碰 domain 内部细节 |
| contracts | 仅自身 | 反向依赖任何实现 |
组合根 *.module.ts(在 interface/)是唯一允许把端口接到实现的地方,boundaries 用 module-root 元素单独放行。
Harness 门禁(从第一个 commit 起强制)
| 机制 | 落点 | 作用 |
|---|---|---|
| 分层边界 | eslint.config.mjs boundaries |
domain/application/interface/infrastructure 越界即 error |
| 时间/随机可控化 | no-restricted-syntax 禁 new Date()/Date.now()/randomUUID();仅 platform/time、access-passcode 豁免 |
统一走 Clock / IdGenerator 端口,消除 flaky |
| 同步事务 | UnitOfWork.run((tx)=>T): T、saveSync(tx,agg): void |
类型层堵死事务内 await(P0-2) |
| zod 单源 + OpenAPI | contracts zod → createZodDto → patchNestJsSwagger();setGlobalPrefix('api') + jsonDocumentUrl:'openapi.json' |
一份 schema 出 REST DTO + Swagger + MCP inputSchema |
| contract-testkit | @platform/contracts/testkit + test/contract/*(CI 必跑) |
第三方/内建 provider 跑同一套 golden 契约 |
| vitest + supertest + MCP | test:unit / test:integration / test:contract / test:e2e |
domain 零 mock、集成真库、e2e 同场景 REST+MCP |
| Drizzle better-sqlite3 | schema/*.sqlite.ts(text+CHECK,不用 pgEnum/.array(),JS Date)+ ./drizzle 迁移 + 迁移测试 |
单机零依赖、PG 双方言可迁移 |
| 部署 harness | docker-compose.yml(docker-socket-proxy 限权 + 127.0.0.1 绑定)+ NoopAuthGuard/PasscodeGuard |
容器逃逸面收敛 + 默认回环 + 访问口令骨架 |
| CI 九步 | .github/workflows/ci.yml |
install → typecheck → lint → unit → contract(必跑) → integration → e2e(必跑) → build → openapi.json diff |
命令
pnpm typecheck # tsc -b(project references,全量类型检查 + 产出 dist)
pnpm lint # eslint(boundaries + no-restricted-syntax),CI 加 --max-warnings=0
pnpm format:check # prettier
pnpm test # 全部 vitest 项目
pnpm test:unit # 仅 domain 零 mock 单测
pnpm test:integration # drizzle saveSync 往返 + 迁移测试
pnpm test:contract # contract-testkit(必跑)
pnpm test:e2e # supertest /api/health + MCP client 冒烟(必跑)
pnpm build # 构建
pnpm openapi:emit # 产出 openapi.json(CI diff 入库)
冒烟切片(本次交付验证的最小闭环)
GET /api/health→ok(口令豁免);/openapi.json暴露。sandbox上下文:Sandbox聚合 +SandboxStatus12 值转移表 + 零 mock domain 单测(stopped→starting合法、pending→running非法)。- 同步
UnitOfWork+ better-sqlite3 迁移 +SqliteSandboxRepository.saveSync+ 集成测试(写入后读回、CHECK 拦截越界枚举)。 - 一个 MCP tool + 一个 REST controller 共注入同一
SandboxApplicationService;supertest e2e + 真实 MCP client(SDK InMemoryTransport)冒烟。 - boundaries 越界与
new Date()均能被 lint 拦下(见下)。
验证 harness 真能拦
# 1) 越界:让 application 直接 import infrastructure 具体类 → lint error
# 在 sandbox-application.service.ts 顶部加:
# import { SqliteSandboxRepository } from '../infrastructure/persistence/sqlite/sandbox.repository.impl';
pnpm lint # → boundaries/element-types: 'application' is not allowed to import 'infrastructure'
# 2) 时间:在任意 domain/application 文件写 new Date() → lint error
pnpm lint # → no-restricted-syntax: Use the Clock port — new Date() is banned
