Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
RoamzyCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
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 withnpm view, version pinning, and MCP registries (Smithery, modelcontextprotocol/servers, etc.).

Each tool returns structured JSON. Tool descriptions (visible viatools/list) encode the agent contract — when to call each tool, what to surface to the user, what to keep internal.
When the MCP server starts withoutROAMZY_API_TOKEN, the first authed call sendsPOST /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 aclaim_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/esimson 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 savingclaim_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 theroamzy_supporttool 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.
- No filesystem access.The server only makes HTTP calls.
- No child processes.
- No environment scanbeyond explicitROAMZY_*variables.
- Outbound traffic only tohttps://roamzy.io(override viaROAMZY_API_BASEif you self-host).
- Purchase toolsare registered only in anonymous mode or withROAMZY_ENABLE_PURCHASE=true.
- Per-token spending capswith cool-off period + big-transaction threshold; configurable per token in/dashboard/settings.
- Service status honoured.Whenroamzy_statusreportspurchases_paused=true, the agent must back off.
- No telemetry.The server doesn't phone home except to call the configured API base.
