GJP ERP AI 销售开单 MCP

基于 AgentScope 2.0.5 的完整销售单 MCP 服务,服务名为 erp-billing。

AI 平台 / SaaS 对话页
  │ Authorization: Bearer <短期 MCP token>

ERP 开单 MCP
  ├─ McpIdentityResolver:解析身份与 billing scopes
  ├─ McpToolSetResolver:按 tenant/account/session 隔离会话
  ├─ BillingToolSet:资料追问、商品匹配、预览和提交
  └─ BillingApiPort
       └─ Adapter:固定 ERP URL + 按会话注入 Bearer

ERP URL 不是租户动态参数,由部署环境唯一配置:

ERP_BILLING_BASE_URL=https://test-ai.yuncyb.com/aicyberp-api

URL 不进入 InvocationContext、CLI Token 请求或 Tool Schema。Bearer 仍按用户会话 隔离;账号、密码、验证码、Cookie 和 Token 都不进入模型可见工具参数。

销售单流程

业务必填项:

  • 客户
  • 出库仓库
  • 经手人
  • 录单日期(YYYY-MM-DD)
  • 商品明细

备注可选,最多 200 字。接口必填的 id=0 与 saveType 由工具内部管理:草稿 0、预收 1、正式 2。

MCP 发布五个工具:

工具 作用
sync_products 同步当前账号可见商品到隔离会话内存
search_products 独立查询真实 ERP 商品
search_sales_order_options 查询客户、仓库或经手人候选
prepare_sales_order 返回缺失项、候选、商品匹配和不可变销售单预览
submit_sales_order 用户确认后以 billing:write 写入真实 ERP

实际调用接口:

GET  /product/page
GET  /customer/page
GET  /warehouse/page
GET  /staff/page
POST /sales/orders

只有 prepare_sales_order 返回 readyToSubmit=true,用户明确确认当前预览,并且 调用身份具有 billing:write 时,才允许提交。submit_sales_order 还要求唯一 idempotency_key;当前实现提供会话内防重,生产多副本应接入共享幂等存储。

本地 CLI 验证

CLI 不提供账号密码或验证码登录,只使用浏览器等渠道已取得的 ERP Token。启动 Token-only 验证服务:

cd /Users/pusonglin/gjp-cyb-mcp
export ERP_BILLING_BASE_URL=https://test-ai.yuncyb.com/aicyberp-api
uv run uvicorn gjp_cli.billing_validation:app --host 0.0.0.0 --port 8102

另一个终端直接启动 CLI,按提示粘贴 ERP Token(输入不回显,可直接粘贴 Bearer ... 或裸 JWT,回车提交):

cd /Users/pusonglin/gjp-cyb-mcp
uv run python -m gjp_cli mcp-chat

如需运行 SaaS 对话模拟器,把上面命令中的 mcp-chat 改为 demo,启动后同样 会提示粘贴 Token。也支持 --upstream-token 或 ERP_BILLING_UPSTREAM_TOKEN 环境变量用于脚本自动化,但交互粘贴不会把 Token 留在 shell history 或进程 参数中。CLI 直接把 ERP JWT 作为 MCP Bearer 使用,无需换票。

已有 MCP Bearer 时直接使用:

uv run python -m gjp_cli mcp-chat \
  --url https://<billing-host>/mcp \
  --token '<ERP JWT>'

开发

uv sync --extra dev
uv run pytest -q
uv run ruff check src tests
uv run python -m gjp_cli doctor
