A remote MCP server that helps an assistant recommend travel eSIM plans for 200+ countries, estimate data needs and hand over a checkout link.
What you can do
Recommend up to three eSIM plans for a destination or multi-country trip, with a reason for each option and a checkout link for the traveler to pay themselves. Search and filter plans by destination, trip length, minimum data and plan type, cheapest first. Estimate data needs from trip length and typical usage. List destinations with ISO code, localized name, plan count and lowest price. Show one plan's data, validity, network, 5G, top-up, carriers and price. Provide short iPhone or Android setup steps and pre-purchase checks.
When to use it
Useful when someone is planning a trip and wants help choosing a travel eSIM, comparing plans across countries, sizing their data needs, or getting setup instructions before or after buying.
Requirements
A remote streamable HTTP endpoint; no package, account, API key or environment variable is declared. The traveler completes payment on the provider's site through the returned checkout link.
Before you install
The server returns checkout links and the traveler pays on the provider's site; the tools themselves never take payment. Plan prices and availability come from the provider and may change. The QR code is emailed and shown in the account after payment.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.bloomyesim%2Fesim/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
Takes the destination (or all destinations of a multi-country trip) and trip length, plus how the traveler uses data if known. Returns up to 3 options with a reason each: best_fit (cheapest that covers the estimated need), budget (cheaper, below the estimate) and roomier (next size up), each with a link straight to checkout confirmation. Accepts every country of a multi-country trip in destinations, with the total days.
Same formula as bloomyesim.com/data-calculator: daily MB per activity x days x Wi-Fi factor x 1.15 safety buffer, rounded up.
