Read-only [MCP](https://modelcontextprotocol.io) server that exposes the [dsh-plugin-certification](https://github.com/PerryLink/dsh-plugin-certification) registry: certification grades, snapshot dates and five-dimension evidence for DeepSeek Harness (DSH) plugins. Zero runtime dependencies, stdio transport.

## Tools

| Tool | Input | Returns |
|---|---|---|
| `get_certification` | `owner`, `repo` | Full certification record (grade, snapshot, five dimensions, veto, notes) or "no record" |
| `list_certified` | — | Every entry in the public registry: repo / grade / snapshot |
| `certification_spec` | — | Spec v1 summary: five dimensions, grade scale, veto rule |

The embedded snapshot lives in `data/certified.json` (synced from the certification repo) and the server refreshes it from the public registry at most once per five minutes. No writes, no secrets, no code execution.

## Install

```sh
git clone https://github.com/PerryLink/dsh-cert-mcp
cd dsh-cert-mcp
node src/index.js        # stdio server
```

Run it directly from the published npm package: `npx @perrylink/dsh-cert-mcp`.

### Register in an MCP client

Claude Code:

```sh
claude mcp add dsh-cert -- node <path-to-repo>/src/index.js
```

Claude Desktop (`claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "dsh-cert": {
      "command": "node",
      "args": ["<path-to-repo>/src/index.js"]
    }
  }
}
```

DSH: add it through [dsh-mcp-panel](https://github.com/PerryLink/dsh-mcp-panel) as a stdio server, or any MCP client that supports `stdio`.

### Install as a DSH bundle

The package declares `dsh.bundle.patch` → `cordis.patch.yml`, so it also installs as a DeepSeek Harness bundle:

```sh
# git channel (latest main)
dsh plugin --profile web add "github:PerryLink/dsh-cert-mcp#main"

# npm channel (published releases)
dsh plugin --profile web add @perrylink/dsh-cert-mcp
```

The inserted row loads the package through the standard Cordis plugin contract: the host half is a plain ESM module exporting `name`, `inject` and `apply(ctx)`. This package ships no browser UI, so there is no `dsh.client` declaration.

```js
// bundle entry (host half) — the contract the patch row loads
export const name = '@perrylink/dsh-cert-mcp'
export const inject = ['tools'] // the host tool surface, provided by dsh-tools
export function apply(ctx) {
  // registers the read-only certification lookup surface
  // (get_certification / list_certified / certification_spec)
}
```

**The host half needs the `tools` service** (shipped by `@deepseek-ai/dsh-tools`). A profile without it does not lose the tools silently: Cordis holds this row in `PENDING` until `tools` exists, which is visible in the profile's plugin list. Nothing else is required — no config keys, no credentials, and no network access at load time.

**Two halves, one data path.** The bundle row and the stdio server are separate entry points over the same `handleRequest` core. The server half is an independent process any MCP client can spawn (`node src/index.js`), and it is *not* part of the plugin path: installing this bundle never starts it, and removing the bundle never touches it. Conversely `npx @perrylink/dsh-cert-mcp` registers nothing on the DSH tool surface.

Remove the bundle with `dsh plugin --profile web remove @perrylink/dsh-cert-mcp` (or delete the row from the profile patch). The standalone stdio MCP server above keeps working for any MCP client.

## Why this exists

The official DeepSeek Harness repository does not run a plugin registry and does not accept external PRs; discovery happens through the `dsh-plugin` GitHub topic and community lists, none of which certify anything. `dsh-plugin-certification` turns "can I install this plugin" into a reproducible five-dimension check (manifest, build hygiene, supply-chain Scorecard, release provenance, sandboxed install smoke test) with a public registry and README badges. This MCP server is the same data with an agent-facing interface: agents can look up a plugin's certification before recommending or installing it.

## Registry

Data source: [PerryLink/dsh-plugin-certification](https://github.com/PerryLink/dsh-plugin-certification) — `data/certified.json`, spec v1.

## Compatibility

- Node `^22.19.0 || >=24.0.0`.
- DSH `>=0.1.2-rc.1 <0.2.0 || >=0.1.5-alpha.1 <0.2.0 || >=0.1.6-0 <0.2.0` (declared in `engines.dsh`, with `dsh.manifestVersion: 1`).
- Peer: `@deepseek-ai/cordis` `^4.0.2`. The host half additionally needs the `tools` service at runtime; the stdio half needs nothing but Node.

## Development

```sh
pnpm install
pnpm run typecheck                            # the one type ruler: checkJs over the published host face
pnpm test                                     # JSON-RPC smoke + the real-Cordis runtime suite
pnpm pack                                     # the published tarball
```

The runtime suite mounts the REAL `SystemPrompt`/`ToolRuntime` registries and asserts that mounting this package puts all three certification tools into `ctx.tools.schemas()`, that disposing the fiber removes them again, and that a context without the `tools` service parks the plugin in `PENDING`. `dsh --dump-config` is deliberately not used as acceptance: a mounted row and a pending fiber look the same there.

There is deliberately **one** type ruler. `@deepseek-ai/*` resolves through this repo's own `node_modules` (the pinned devDependencies — the published line) and the package declares no DSH peer, so a second `tsc` configuration would be the same command over the same type universe. The `typecheck:ci` script is kept as the historical no-op duplicate (its only extra key is an empty `paths: {}`) for compatibility with existing references, not as a second face. The independent second piece of evidence is the runtime mount gate above.
