TracePass MCP Server

A Model Context Protocol server for TracePass — the EU Digital Product Passport platform. It lets AI assistants (Claude, Cursor, IDE agents) manage products, Digital Product Passports, economic-operator parties, and GS1 EPCIS 2.0 supply-chain events.

It speaks the full MCP protocol — tools, resources, resource templates, and prompts.

Two ways to use it

The same server core ships two ways:

1. Hosted — point your MCP client at https://ai.tracepass.eu/mcp. Nothing to install; always current.
2. Local (npm) — run tracepass-mcp-server via npx. The MCP client launches it as a subprocess and speaks MCP over stdio.

Both need a TracePass API key — mint one in the dashboard under Developer → API Keys (a tp_… key).

Configuration

Hosted

{
  "mcpServers": {
    "tracepass": {
      "url": "https://ai.tracepass.eu/mcp",
      "headers": { "Authorization": "Bearer tp_YOUR_KEY" }
    }
  }
}

Local (npx / stdio)

{
  "mcpServers": {
    "tracepass": {
      "command": "npx",
      "args": ["-y", "tracepass-mcp-server"],
      "env": {
        "TRACEPASS_API_KEY": "tp_YOUR_KEY"
      }
    }
  }
}

Optional env var: TRACEPASS_BASE_URL (defaults to https://app.tracepass.eu) — point the tools at a different TracePass deployment.

Tools

The ~23 TracePass v1 API operations are grouped into 5 tools, each taking an action plus action-specific args:

A note on writes

Some actions cost money or are irreversible — the server's tool descriptions tell the model so:

• tracepass_passports create consumes a billable DPP slot on the account's plan. Over-quota creation incurs a per-passport overage charge; the tool surfaces a 402-style message and only proceeds with args.confirmOverage: true after the user agrees.
• tracepass_passports archive is irreversible — the public QR permanently 404s. Use suspend (reversible) when a change might be undone.
• tracepass_epcis capture / query require the paid EPCIS add-on; export is included on Starter plans and up.

Resources

Read-only entity data you can attach as conversation context:

• tracepass://products — the product catalogue
• tracepass://product/{id} — one product
• tracepass://passport/{id} — one passport, full field detail
• tracepass://passport/{id}/epcis — a passport's EPCIS 2.0 events

Prompts

Reusable DPP workflows the client surfaces as slash-commands:

• audit_passport — review a passport for completeness and compliance readiness
• onboard_product — create a product and its first passport
• review_epcis_events — summarise a passport's supply-chain trail

Development

npm install
npm run build        # tsc -> dist/
npm run typecheck
npm test             # vitest
npm run lint
npm start            # run the hosted HTTP service locally (:8080)
npm run start:stdio  # run the stdio server locally

The hosted service is a plain Node HTTP server (dist/http.js), stateless — each request carries its own API key and builds a fresh MCP session. It is containerised via the Dockerfile and deployed to Hetzner; see tracepass-environment/docker-mcp.yml.
