Quartermaster
A store built for AI agents to shop in, on behalf of the people they work for. Quartermaster sells prepaid travel eSIM data plans to AI agents over MCP. Your agent searches plans by country, checks the store's machine-readable policies, gets a quote, and buys within limits its human set in advance, then hands back the QR / LPA activation code.
The human stays in control. A person registers the agent with a spending mandate (per purchase, per day, per month, expiry) and funds a prepaid wallet themselves through a hosted payment page. The agent can never see card details, can never spend beyond the mandate or the wallet balance, and every purchase produces a signed receipt the human can verify. Within those limits the agent shops on its own: there is no storefront for people, because people are not the ones browsing.

Tools
| Tool | What it does |
|---|---|
register_agent | Register an agent for a principal with a spending mandate (per transaction, day, month, expiry). Returns agent_key and, for a new principal, principal_key. |
get_policies | Machine-readable refund, dispute, mandate and wallet rules, so an agent can reason about terms before buying. |
search_plans | Search eSIM plans by country, region, data and validity. |
get_quote | Lock a price for a plan. |
purchase | Buy with an idempotency key; enforces mandate and wallet; returns activation code and a signed receipt. |
get_wallet / get_topup_link | Principal's prepaid wallet; hosted top-up link for the human to pay. |
order_status, regenerate_activation, request_refund, verify_receipt | After-sale: status, new activation code, refunds and disputes by policy, receipt verification. |
rotate_principal_key | Rotate the principal's ownership key. |
Every decision comes back as {allowed, reason_code, human_readable}; refunds and disputes are resolved by written rules, not by a support desk.
Why agent-only
Other eSIM MCP servers help an agent compare plans. Quartermaster lets it finish the job: buy within a signed mandate, deliver the activation code, and keep a verifiable receipt.
Agents don't need a homepage. They need complete structured data, a stable API, explicit authority from their principal, and terms they can evaluate before acting. Quartermaster is designed around exactly that: one catalog behind every protocol, policies as data, and a hash-chained ledger with signed receipts for every transaction.
