UK Logistics (buy Royal Mail + more labels + tracking via Shippo)

Use it in 60 seconds

Paste this into your MCP client config (Claude Desktop, Cursor, Windsurf, or any MCP-capable agent):

{
  "mcpServers": {
    "uk-logistics": {
      "type": "http",
      "url": "https://logi-uk.wishpool.app/mcp"
    }
  }
}

Nothing to install. Credentials, when you need them, travel as HTTP headers on each request and are never stored — see the threat model.

Or run it yourself

Would you rather not send production credentials to a server you do not control? Deploy this identical code to your own account and point your agent at your own URL:

Deploy with Vercel

git clone https://github.com/junter1989k-ai/uk-logistics-mcp && cd uk-logistics-mcp && npx vercel --prod

Remote MCP server that lets any AI agent buy UK shipping labels — Royal Mail Tracked 24/48 and more — with automatic cheapest-rate selection, track parcels, and refund unused labels via the Shippo shipping API. Royal Mail runs on Shippo's master account, so no Royal Mail contract or merchant courier account is needed. Stateless, bring-your-own API token, never stores anything. Free Shippo test tokens give zero-cost end-to-end labels.

Live endpoint: https://logi-uk.wishpool.app/mcp · Registry: app.wishpool/uk-logistics-mcp

Quick start

{
  "mcpServers": {
    "uk-logistics": {
      "type": "http",
      "url": "https://logi-uk.wishpool.app/mcp",
      "headers": {
        "x-shippo-token": "shippo_test_your_test_or_shippo_live_prod_token"
      }
    }
  }
}

No shared demo — but test tokens are free. Shippo issues free TEST tokens (prefix shippo_test_…) that run the full flow end-to-end at no cost: sign up with no card at apps.goshippo.com/join → API. Production tokens (prefix shippo_live_…) buy real labels. The same server auto-selects the environment from the token prefix.

Royal Mail without a Royal Mail contract

Royal Mail Tracked 24/48 runs on Shippo's master carrier account, so an AI agent can print a Royal Mail label with no Royal Mail contract and no merchant courier account — just a free Shippo token. The carrier parameter stays open, so a merchant with its own carrier account on Shippo can select it instead.

Tools

Tool	What it does
create_shipment	Buy a UK label. to_* + from_* address fields (county/state optional), parcel weight (grams by default, required) and length/width/height (centimetres by default). Optional carrier/service restrict the choice (e.g. Royal Mail / Tracked 24) — default is the cheapest rate across all available carriers. Fetches rates, buys the chosen rate, returns shipment_id, transaction_id, tracking_number, printable label_url, carrier, service and the rate (GBP).
query_tracking	Track by tracking_number + carrier token (default royal_mail; use shippo with SHIPPO_TRANSIT/SHIPPO_DELIVERED for TEST tokens). Returns status from the Shippo enum — UNKNOWN / PRE_TRANSIT / TRANSIT / DELIVERED / RETURNED / FAILURE — plus a plain-English hint; non-terminal statuses carry next_steps. Raw carrier scans always included.
refund_label	Refund an unused label by transaction_id. Returns refund_status: QUEUED / PENDING / SUCCESS / ERROR. Only labels never scanned by the carrier are eligible — an already-shipped label cannot be refunded.

Owner policy guardrails ride optional headers (x-agentpay-max-amount, x-agentpay-approval-above, x-agentpay-allowed-tools) — set by the human owner in client config; the agent cannot relax them. The label price is gated before any purchase: approval-above returns an unsigned draft with the shipment/rates prepared but no label bought.

Develop

node test/serve.js   # local server on :3247 (/mcp)
node test/e2e.js     # protocol + validation + policy/shippo units + fake-token live probe to api.goshippo.com (expects native 401)

How it talks to Shippo

create_shipment is two server-to-server REST calls: POST /shipments/ (to/from address + parcel → rates[]) then POST /transactions/ (chosen rate object_id → label_url + tracking_number). query_tracking is GET /tracks/{carrier}/{tracking_number}. refund_label is POST /refunds/ (by transaction id). Auth is the header Authorization: ShippoToken <token>; the token prefix (shippo_test_… / shippo_live_…) selects test vs production on the same base URL https://api.goshippo.com.

Safety

Pure stateless translation layer. The label is generated and served by Shippo/the carrier; the Shippo API token travels per-request in a header, nothing is stored. Parcels flow sender ↔ carrier ↔ recipient directly. Privacy policy.

Sister servers

US labels (USPS/UPS/FedEx) live in usa-logistics-mcp; Taiwan CVS pickup + home delivery in taiwan-logistics-mcp. One family of stateless BYO local-commerce MCP servers: local payments in 81 countries at mcp.wishpool.app, plus electronic-invoice servers across nine countries including Mexico CFDI, Brazil NF-e, Chile DTE, Peru CPE and India GST.
