dsh-mcp-manage

Label: dsh plugin · A DeepSeek Harness (DSH) static plugin that adds an MCP 服务 management page in Settings.

Manage the MCP servers DSH registers through cordis.patch.yml: list / add / edit / delete each MCP service, and — most importantly — run a real MCP initialize connection handshake against every server so you can see at a glance whether each MCP service connects normally.

Install — one command, restart-persistent

This is a static DSH plugin (the same shape as a plugin-market package): once installed it is a dependency of the profile and is loaded by the bundle layer on every boot — it survives restarts, no pasting code, no cordis_define.

✅ Recommended (use the DSH wrapper, not bare pnpm add)

dsh plugin --profile web add dsh-mcp-manage

• This runs pnpm add, then auto-reconciles dsh.profile.bundles in <profile>/package.json: because the package declares dsh.bundle, it joins the profile layer stack automatically. No manual insert: editing — DSH reads the package's dsh.bundle.patch (static/cordis.patch.yml) at boot and turns it into an active loader entry.
• The plugin's host and client load on the next DSH start, so restart DSH (e.g. stop and relaunch dsh web), then open Settings → MCP 服务. If the page doesn't appear, hard-refresh the browser (Ctrl/Cmd+Shift+R).

⚠️ Gotcha: a bare pnpm add dsh-mcp-manage installs the package into node_modules and dependencies but does not add it to dsh.profile.bundles — so it never becomes a loaded layer and the page won't appear after restart. Always install through dsh plugin ... add, which does the reconcile step for you.

If dsh is not on your PATH

dsh is shipped as a npx/npm-cache binary, so a terminal that lacks the right PATH may report dsh: not recognized. Any of these works:

# 1) new terminal (often fixes PATH) then the normal form:
dsh plugin --profile web add dsh-mcp-manage

# 2) wrap in npx — independent of PATH:
npx --yes @deepseek-ai/dsh plugin --profile web add dsh-mcp-manage

# 3) invoke the packed bin directly with node (never depends on PATH):
node "<npm-cache>\_npx\<hash>\node_modules\@deepseek-ai\dsh\lib\bin.js" plugin --profile web add dsh-mcp-manage

Upgrading a later version

After you bump the version and publish a new release, update the installed copy, then restart DSH:

dsh plugin --profile web update dsh-mcp-manage

Uninstalling

dsh plugin --profile web remove dsh-mcp-manage

This runs pnpm remove and reconciles dsh.profile.bundles, so the package is removed from node_modules, from dependencies, and from the profile layer stack in one command — no manual cordis.patch.yml edits needed. The change takes effect on the next DSH restart (the already-running process keeps the old layer until then).

As with install, use the dsh plugin ... wrapper rather than a bare pnpm remove — the wrapper is what also drops the entry from dsh.profile.bundles; a bare pnpm remove would leave a stale bundle-layer reference.

What happens under the hood

The package carries a dsh.bundle.patch (static/cordis.patch.yml):

- insert:
    - id: dsh-mcp-manage
      name: 'dsh-mcp-manage'

so DSH's bundle layer turns it into an active loader entry automatically. You only need to add the dependency once (through dsh plugin ... add); the UI page and routes appear after a restart.

Its manifest is also compatible with the built-in plugin market (dshmarket), so it could be listed there too — but this package is primarily distributed as an npm package installed via dsh plugin ... add dsh-mcp-manage.

TL;DR (what you get)

• A Settings → MCP 服务 section (settings.section → id mcp-manage, order 30).
• One card per configured MCP server: id / serverName / transport / command-or-url / headers-or-env plus a status badge (已连接 / 可达 / 异常 / 未知).
• 检测 (probe one) / 重新检测全部 run a real MCP initialize handshake, not a ping:
  • streamable-http → a real authenticated POST initialize session via the official MCP SDK.
  • stdio → actually spawns the server command and completes an MCP initialize over stdio.
• 添加服务 / 编辑 / 删除 persist changes straight back to cordis.patch.yml (insert:-blocks for @deepseek-ai/dsh-mcp-client).

Architecture — this is a real static plugin

The dynamic plugin the author originally shipped used the dynamic-runner sandbox APIs (harness.handle / host.call), which only exist inside dsh-cordis-*-runner. A static plugin runs in the normal (non-sandbox) plane and gets no harness/host.call; it uses the real services instead. This package is ported to that model:

layer	file	does what
Host (Node)	static/index.js	ESM Cordis plugin exporting name + apply(ctx, config). ctx.inject(['webServer'], …) mounts HTTP routes /dsh-mcp/list, /dsh-mcp/check, /dsh-mcp/save. Uses real node:fs / node:os / node:child_process.
Client (browser)	static/client.js	A window.__ModuleLoader__.load({ id, factory }) bundle (only external is react). Registers settings.section via ctx.slots.inject(...) and fetch()es the host routes.
Bundle patch	static/cordis.patch.yml	dsh.bundle.patch → inserts { id: dsh-mcp-manage, name: 'dsh-mcp-manage' } so the loader activates it.
Probe	probe/dsh-mcp-probe.cjs	Standalone real-MCP initialize handshake (official @modelcontextprotocol/sdk), self-terminating.

Host routes

route	method	purpose
/dsh-mcp/list	GET	list servers + the auto-detected profile patch path
/dsh-mcp/check	GET	run a real handshake per server → {id, status, message} each
/dsh-mcp/save	POST	persist the edited server list back to cordis.patch.yml (same-origin only)

Auto-detection (no hardcoded paths)

The host derives the runtime layout the same way the dynamic host did, but with real Node:

• DSH_HOME (an existing .dsh directory) or HOME → <profilesRoot>.
• profilesRoot = <DSH_HOME>/profiles (or <HOME>/.dsh/profiles).
• SDK_ROOT = <profilesRoot>/node_modules.
• PATCH_PATH = first <profilesRoot>/<p>/cordis.patch.yml whose content references @deepseek-ai/dsh-mcp-client; PATCH_DIR = its directory, where dsh-mcp-probe.cjs is written.

Package manifest (what makes it a static, installable plugin)

package.json satisfies the exact contract the DSH client loader validates, so the package loads as a real static plugin once installed (and would also be eligible for a plugin-market listing):

• main → ./static/index.js (host entry artifact).
• exports["./client"] → ./static/client.js (browser bundle).
• dsh.client.platform: "web" (+ optional inject).
• dsh.bundle.patch → static/cordis.patch.yml.
• peerDependencies["@deepseek-ai/cordis"] ≥ ^4.0.1.

These match what dshmarket itself ships and what dsh-client-modules requires (parseDshClient needs platform:"web", clientExportOf needs exports["./client"]).

plugin/ (the original dynamic harness.handle/host.call version) is kept in the git history for reference; the installable package uses static/. If you want the dynamic, session-only variant instead, see the plugin/*.js source in an earlier commit.

Standalone probe (no DSH needed)

# stdio server
node probe/dsh-mcp-probe.cjs "{\"sdkRoot\":\"/abs/path/node_modules\",\"transport\":\"stdio\",\"command\":\"/abs/path/server\",\"args\":[\"stdio\"],\"env\":{\"TOKEN\":\"...\"},\"timeoutMs\":15000}"

# streamable-http server
node probe/dsh-mcp-probe.cjs "{\"sdkRoot\":\"/abs/path/node_modules\",\"transport\":\"streamable-http\",\"url\":\"https://host/mcp\",\"headers\":{\"Authorization\":\"Bearer ...\"},\"timeoutMs\":15000}"

probe is also wired as an npm script: npm run probe -- "<spec-json>".

Credentials (e.g. Authorization: Bearer …, GITHUB_PERSONAL_ACCESS_TOKEN) go only into the probe process; the result reports only ok / name / ver / error, never the headers.
