Bloomberg MCP Gateway

生产级 MCP 网关，通过私有 Tailscale 网络，让 Linux 托管的代理（Hermes）受控访问 Windows Bloomberg Terminal 工作站上的 Bloomberg Desktop API（blpapi）。

  • 协议： 无状态 MCP Streamable HTTP，修订版 2026-07-28

  • 传输： 通过 Tailscale Serve 的 HTTPS → http://127.0.0.1:8765

  • Bloomberg： 仅 Desktop API，本地 127.0.0.1:8194（BBComm 永不暴露）

  • 认证： 私有静态 bearer 令牌，映射到服务器拥有的主体

  • 安全： 策略、成本/配额预算、主体绑定句柄、审计跟踪、权限熔断器、有界结果存储

  • CI： 确定性假后端，无需 Bloomberg Terminal 即可进行开发和测试

完整设计规范见 SPEC.md。

开发环境搭建（Windows）

需要 Python 3.12 和 uv。所有工作都在项目本地虚拟环境（.venv）中进行；绝不触碰全局 Python 环境。

# 1. Create the isolated virtual environment
uv venv

# 2. Install the gateway with dev tooling (blpapi is fetched from the
#    Bloomberg package index automatically, see pyproject.toml)
uv sync --extra dev

# 3. Run the test suite against the deterministic fake backend
uv run pytest

# 4. Lint and type-check
uv run ruff check src tests
uv run mypy

没有 uv 时，等效的纯 Python 流程为：

python -m venv .venv
.venv\Scripts\python -m pip install -e ".[dev]" `
  --extra-index-url https://blpapi.bloomberg.com/repository/releases/python/simple/

运行网关

# Fake backend (no Bloomberg Terminal required)
uv run bloomberg-mcp --backend fake

# Native backend (Bloomberg Terminal must be running and logged on)
uv run bloomberg-mcp --config config/default.yaml --policy config/policy.example.yaml

网关默认绑定 127.0.0.1:8765，并拒绝重复启动（Windows 命名互斥体）。请单独配置 Tailscale Serve（scripts/configure-tailscale.ps1）以终止仅限 tailnet 的 HTTPS。

安全说明

  • 切勿在 localhost 之外暴露端口 8765 或 BBComm 端口 8194。

  • Bearer 令牌必须具有 >= 256 位的熵；以有界重叠方式轮换。

  • 策略限制不能替代 Bloomberg 合同或权限限制。
