dsh-mcp-host
将 stdio MCP 服务器（Playwright、Chrome DevTools、任何 MCP）作为原生 DeepSeek Harness 工具公开。仅限主机端，无客户端捆绑包。
插件会安装到这里；不确定时保持 web。
npx -y @deepseek-ai/dsh plugin --profile web add github:imaused/dsh-mcp-bridge#ceb9467a9a13715ef1f7dc5ab33bf01a3c97d803Mcp Host 以 dsh-mcp-host 发布，当前版本为 0.1.0。Plugin Hub 会校验它的 manifest，并保存精确安装来源，便于复现安装结果。
Expose any stdio MCP server as native DeepSeek Harness tools. Host-only plugin, no browser UI, no npm dependencies.
Built for one job: let a DSH agent drive a browser through the official Microsoft Playwright MCP server, attached to the Edge/Chrome you are already using.
npx --yes @playwright/mcp@latest --cdp-endpoint=msedge).initialize + tools/list, converts each tool's JSON Schema into a DSH parameter schema, and registers it with ctx.tools.register.tools/call; the result is returned as JSON. Images (screenshots) are written to a temp file and returned as a path, not as base64.Tools are renamed: browser_navigate becomes edge_navigate (prefix configurable).
edge_navigate, edge_navigate_back, edge_snapshot, edge_click, edge_type, edge_fill_form, edge_press_key, edge_tabs, edge_take_screenshot, edge_evaluate, edge_wait_for, edge_close.
The full set costs prompt space in every session, which is why it is not the default. Set MCP_BRIDGE_ALL=1 to expose everything.
cd E:\dsh
.\rollback.cmd guard add "file:C:\path\to\dsh-mcp-host"
.\rollback.cmd health
Restart DSH (or rely on hot-load) and open a new session.
| Env var | Default | Meaning |
|---|---|---|
MCP_BRIDGE_COMMAND | npx --yes @playwright/mcp@latest --cdp-endpoint=msedge | The MCP server command line (any stdio MCP server) |
MCP_BRIDGE_PREFIX | edge | Tool name prefix |
MCP_BRIDGE_ALL | unset | 1 = register every tool the server offers |
MCP_BRIDGE_TOOLS | unset | Comma-separated allow-list of MCP tool names |
MCP_BRIDGE_TIMEOUT | 120000 | Per-call timeout (ms) |
MCP_BRIDGE_INIT_TIMEOUT | 30000 | Startup timeout (ms) |
Open edge://inspect/#remote-debugging (or chrome://inspect/#remote-debugging) and enable Allow remote debugging for this browser instance. Then --cdp-endpoint=msedge (or =chrome) attaches to that running browser with your logins and extensions. Without the toggle, Playwright launches a fresh browser instead.
If the MCP server cannot start or does not answer, the plugin registers nothing and logs the reason 鈥?it never throws, so it cannot take the host boot down. Check MCP_BRIDGE_INIT_TIMEOUT and the stderr tail printed in the DSH console.
The bridge itself makes no network calls. It spawns exactly one child process (the MCP server you configured) and forwards bytes between it and the tool call. With --cdp-endpoint, the MCP server attaches to your existing browser, which means it can see and act on the tabs you have open 鈥?treat that as giving the agent your browser session.
