dsh-cert-mcp

Read-only MCP server that exposes the 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

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:

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

Claude Desktop (claude_desktop_config.json):

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

DSH: add it through 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:

# 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 apply(ctx) (declaring inject only when it needs services). This package ships no browser UI, so there is no dsh.client declaration.

// bundle entry (host half) — the contract the patch row loads
export function apply(ctx) {
  // registers the read-only certification lookup surface
  // (get_certification / list_certified / certification_spec)
}

Remove it 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 — data/certified.json, spec v1.
