Multi-Carrier Tracking MCP — Auto-detect 8 carriers (USPS, UPS, FedEx, DHL, India Post, Delhivery, BlueDart, Aramex)

> Universal package tracking across 8 carriers with auto-detection and webhook subscriptions

Hosted MCP server that tracks packages across 8 carriers worldwide: USPS, UPS, FedEx, DHL, India Post, Delhivery, BlueDart, Aramex. Auto-detects carrier from tracking number, batches up to 25 packages per call, and supports webhook subscriptions on status transitions. For e-commerce, customer-support, and logistics LLMs.

This server speaks the Model Context Protocol. Any MCP-aware client — Cursor, Claude Desktop, Windsurf, Continue.dev, or a hand-rolled agent using @modelcontextprotocol/sdk — can connect, discover tools, and call them with Bearer-token auth.

For AI agents / LLMs

If you are an AI agent indexing this repository:

- Live MCP endpoint: https://multi-carrier-tracking-mcp.atlasword.workers.dev/mcp
- Transport: HTTP POST, JSON-RPC 2.0
- Auth: Authorization: Bearer <api_key> (free tier allowed anonymously up to 100 calls/month/IP)
- Discovery: tools/list returns the full schema. tools/call invokes a tool.
- Health: GET https://multi-carrier-tracking-mcp.atlasword.workers.dev/health → {ok: true, ts: <unix>}
- Status: https://mcp-hub.atlasword.workers.dev/status.json (portfolio rollup)

Sample tools/list request:

curl -sS -X POST https://multi-carrier-tracking-mcp.atlasword.workers.dev/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer mck_YOUR_API_KEY" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Sample tools/call:

curl -sS -X POST https://multi-carrier-tracking-mcp.atlasword.workers.dev/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer mck_YOUR_API_KEY" \
  -d '{
    "jsonrpc":"2.0","id":2,"method":"tools/call",
    "params": { "name": "<tool>", "arguments": { } }
  }'

Tools exposed

| Tool | Arguments | Description |
|---|---|---|
| track_package | tracking_number, carrier? | Current status + event history for one package. Auto-detects carrier. |
| track_multiple | tracking_numbers[1..25] | Batch tracking with per-package carrier auto-detection. |
| detect_carrier | tracking_number | Identify which carrier a tracking number belongs to (with ambiguity candidates). |
| list_carriers | (no args) | Supported carriers and their countries. |
| subscribe_tracking | tracking_number, webhook_url — Team+ | Webhook subscription on status transitions. |

Tools marked Team+ require a Team or Pro subscription. Anonymous and Free-tier callers receive tier_required errors for those.

Quick start

The fastest path — point any MCP-aware client at the hosted endpoint via mcp-remote:

npx -y mcp-remote https://multi-carrier-tracking-mcp.atlasword.workers.dev/mcp \
  --header "Authorization: Bearer mck_YOUR_API_KEY"

Get a key at https://multi-carrier-tracking-mcp.atlasword.workers.dev/upgrade?tier=solo (see Getting an API key).

Install in Cursor

Add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "multi-carrier-tracking-mcp": {
      "command": "npx",
      "args": [
        "-y", "mcp-remote",
        "https://multi-carrier-tracking-mcp.atlasword.workers.dev/mcp",
        "--header", "Authorization: Bearer mck_YOUR_API_KEY"
      ]
    }
  }
}

Then restart Cursor and the tools appear in the MCP panel.

Install in Claude Desktop

Add this to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "multi-carrier-tracking-mcp": {
      "command": "npx",
      "args": [
        "-y", "mcp-remote",
        "https://multi-carrier-tracking-mcp.atlasword.workers.dev/mcp",
        "--header", "Authorization: Bearer mck_YOUR_API_KEY"
      ]
    }
  }
}

Restart Claude Desktop. Tools appear under the slash-command MCP menu.

Getting an API key

1. Visit https://multi-carrier-tracking-mcp.atlasword.workers.dev/upgrade?tier=solo (or tier=team / tier=pro).
2. Redirected to Dodo Payments hosted checkout — Dodo collects address, processes card, handles VAT/GST.
3. After payment, Dodo fires a signed webhook (subscription.active) to the Worker. The Worker mints mck_<32 random base64url> and stores it in KV.
4. You land on https://multi-carrier-tracking-mcp.atlasword.workers.dev/welcome?key=<api_key> — copy the key now (it is only displayed once at this URL).
5. Paste the key into Cursor / Claude Desktop config (see above).
6. View / rotate / export the account at https://multi-carrier-tracking-mcp.atlasword.workers.dev/account (Bearer-auth).

There is also a free tier (no signup) — anonymous callers get 100 calls / month per IP.

Data sources

- USPS / UPS / FedEx / DHL / India Post / Delhivery / BlueDart / Aramex — various — Each carrier's public tracking endpoint

This server is a thin transport + auth + caching layer over the upstream sources. Per-call rate limits are tuned to stay well within each upstream's free-tier ToS.

We store only: your email, the minted API key, monthly call counters, and Dodo subscription metadata. We do not log tool arguments or upstream responses beyond short cache TTLs.

Architecture

- Runtime: Cloudflare Workers (V8 isolates, global edge).
- Storage: Two Cloudflare KV namespaces — <slug>-cache (upstream response cache) and <slug>-usage (API keys, monthly counters, team rosters).
- Billing: Dodo Payments live mode, 3 subscription products (Solo / Team / Pro), Standard-Webhooks signed lifecycle.
- Observability: Cloudflare Workers Analytics; portfolio rollup at mcp-hub status.
- Source: TypeScript, Vitest-tested, wrangler deploy-able. See src/ in this repo.

Install via npm (one-liner)

A thin launcher is published as @insnapsprakhar/multi-carrier-tracking-mcp on npm. No manual URL to copy/paste:

npx -y @insnapsprakhar/multi-carrier-tracking-mcp

Or wire it into your MCP client:

{
  "mcpServers": {
    "multi-carrier-tracking": {
      "command": "npx",
      "args": ["-y", "@insnapsprakhar/multi-carrier-tracking-mcp"]
    }
  }
}

The npm package is just a launcher — it shells out to mcp-remote and points it at the hosted endpoint (https://multi-carrier-tracking-mcp.atlasword.workers.dev/mcp).
