Assessment: atoship gives agents twelve MCP tools and a REST API for US labels with published per-unit fees, free sign-up, test keys and a wallet the agent cannot overspend. No status page, rate-limit figures, OpenAPI spec or changelog was found, and the npm MCP package has not changed since February 2026.

## Before you call it

1. Use an `ak_test_` key until the user confirms live labels; test mode creates no real labels
2. Ask the user before `purchase_label`, since it spends the wallet balance
3. Call `void_label` promptly for a mistaken label, and check the carrier's refund rules
4. Branch on `error.code`, and on 429 wait `error.retryAfter` seconds
5. Validate the address with `validate_address` before buying; the standalone endpoint costs $0.03 a call

## Connect

```bash
npx -y @atoship/mcp
```

```bash
