Roamzy Io Mcp Server

@roamzy/mcp-server

MCP server for Roamzy — buy and manage a global eSIM through Claude Desktop, Cursor, Continue, Cline, Windsurf, Zed, or any other Model Context Protocol client. Anonymous flow by default: no account required to use it.

Agents don't just buy — they earn. A built-in referral pays you 20% of every payment from anyone you refer — a human user or another AI agent — forever. Even anonymous agents earn from day one, no signup. That's the distribution flywheel: an agent that earns has a reason to tell the next agent.

> One eSIM for 193 countries. Pay per actual MB used. USDT or USDC on your > preferred network. No packages. No expiry. No subscription.

What it does

This MCP server lets an agent (running in any MCP-compatible client) call the Roamzy HTTP API on the user's behalf. Sample conversation in Claude Desktop:

> User: I'm going to Thailand for a week, buy me an eSIM. > > Claude: Roamzy — one universal eSIM, works in 193 countries. Billed per > MB at the local rate, no packages, no expiry. For Thailand the rate is > ~$2.15/GB. Which stablecoin / network do you want to pay with? > (USDT on TRON, BSC, Polygon, Optimism, Arbitrum, TON — or USDC on Solana, > BSC, Polygon, Optimism, Arbitrum.) Minimum top-up is $20 USDT. > > User: USDC on Solana, $20. > > Claude: Order created. eSIM number 2040XXXXXX. Pay here: [pay-link]. > After ~1 minute on Solana, I'll fetch your QR. > ❗ Save this recovery URL so you can return to this eSIM from another > Claude chat: [claim-link]. > > User pays $20 USDC. > > Claude: Paid. Here's your activation QR — open Settings → Cellular → > Add eSIM and scan it with your phone camera. [QR PNG attached]

The server doesn't run a backend itself — it's a thin client to https://roamzy.io/api/v1/*, mapped 1:1 to MCP tools.

Install

Add this to your MCP client's configuration (e.g. ~/Library/Application Support/Claude/claude_desktop_config.json for Claude Desktop on macOS):

{
  "mcpServers": {
    "roamzy": {
      "command": "npx",
      "args": ["-y", "@roamzy/mcp-server"]
    }
  }
}

Restart your MCP client. The first authed tool call will mint an anonymous Roamzy account automatically — no signup required.

Alternative: install from a hosted tarball

If you can't reach the npm registry, want to pin a pre-release, or prefer to fetch a specific version directly from Roamzy's CDN, swap the args to a URL:

"args": ["-y", "https://roamzy.io/mcp/roamzy-mcp-latest.tgz"]

Both forms run the same code — the npm registry path is the recommended default because it integrates with npm view, version pinning, and MCP registries (Smithery, modelcontextprotocol/servers, etc.).

Optional environment variables

| Variable | Default | Purpose | |---------------------------|------------------------------------|--------------------------------------------------------------------------------------------------------| | ROAMZY_API_TOKEN | (unset → anonymous mode) | Use a pre-existing API token from /dashboard/settings instead of an anonymous account. | | ROAMZY_ENABLE_PURCHASE | false (but true in anon mode)| When using a non-anonymous token, opt-in flag required to expose purchase tools. | | ROAMZY_API_BASE | https://roamzy.io/api/v1 | Override for staging / self-hosted backends. |

Tools

Public (no auth required)

| Tool | Purpose | |----------------------------|------------------------------------------------------------------------------------------| | roamzy_status | Service status + agent-pause flags. Call before any purchase attempt. | | roamzy_list_countries | Reference list of all 193 supported countries with per-MB rates. | | roamzy_country_detail | Per-MB rate for one country. | | roamzy_estimate | Reference calc: «how many USDT would N MB cost in country X». | | roamzy_support | Official support channels + recovery procedure. Call instead of web-searching. | | roamzy_payment_options | Currently-enabled stablecoins + networks (live from NowPayments). Call before order. |

Account-scoped (anonymous or token)

| Tool | Purpose | |----------------------------|------------------------------------------------------------------------------------------| | roamzy_me | Current Roamzy account info (auto-mints anonymous account on first call). | | roamzy_list_esims | The account's eSIMs with MSISDN, status, balance. | | roamzy_get_esim | One eSIM's activation details (QR payload, LPA URI). Generate the QR PNG locally. | | roamzy_order_status | Poll a pending order: waiting → confirming → finished. |

Purchase (anonymous or token + ROAMZY_ENABLE_PURCHASE=true)

| Tool | Purpose | |----------------------------|------------------------------------------------------------------------------------------| | roamzy_create_order | Mint a new eSIM and fund it. Min top-up $20 USDT. Requires pay_currency from options. |

Each tool returns structured JSON. Tool descriptions (visible via tools/list) encode the agent contract — when to call each tool, what to surface to the user, what to keep internal.

Anonymous flow

When the MCP server starts without ROAMZY_API_TOKEN, the first authed call sends POST /api/v1/anon-session (no auth) to mint a fresh anonymous Roamzy account. The server caches the returned token in-process (never written to disk) and uses it for subsequent calls.

The response also includes a claim_url — a magic-link that lets the user later attach this anonymous account to a permanent Google or Telegram identity. Once attached, the eSIM, balance, and history become visible from /dashboard/esims on the web.

Important: the anonymous token lives only in this MCP server process. If the user closes their MCP client (e.g. quits Claude Desktop) without saving claim_url, the access path is lost — the eSIM itself keeps working, but the user can't see or manage it from a new session. The recovery procedure (operator-mediated via support) is described in the roamzy_support tool response.

Anonymous accounts have conservative daily / monthly spending caps and a cool-off period that gates large transactions; exact thresholds are shown to the user in the dashboard once they claim.

Security model

• No filesystem access. The server only makes HTTP calls.
• No child processes.
• No environment scan beyond explicit ROAMZY_* variables.
• Outbound traffic only to https://roamzy.io (override via

ROAMZY_API_BASE if you self-host).

• Purchase tools are registered only in anonymous mode or with

ROAMZY_ENABLE_PURCHASE=true.

• Per-token spending caps with cool-off period + big-transaction

threshold; configurable per token in /dashboard/settings.

• Service status honoured. When roamzy_status reports

purchases_paused=true, the agent must back off.

• No telemetry. The server doesn't phone home except to call the

configured API base.

See [SECURITY.md](./SECURITY.md) for the disclosure policy.
