PuraSIM MCP server — travel eSIM plans for AI assistants

Remote Model Context Protocol server for PuraSIM, a travel eSIM store. It lets Claude, ChatGPT, Cursor, VS Code and any MCP client search PuraSIM's prepaid data plans for 187 countries and territories, recommend a plan for a trip, check coverage and mobile networks, and return a link where the user can buy the plan on purasim.com.

https://api.purasim.com/mcp

• Transport: Streamable HTTP (stateless, JSON responses)
• Authentication: none. It only reads the public catalog, the same data shown on purasim.com
• Read-only: no tool places an order, takes a payment or touches an account
• Data: the live PuraSIM catalog (about 3,400 plans), rebuilt daily from the store and the network provider

Connect

Claude (claude.ai and Claude Desktop): Settings → Connectors → Add custom connector → paste https://api.purasim.com/mcp.

Claude Code:

claude mcp add --transport http purasim https://api.purasim.com/mcp

ChatGPT (developer mode): create a custom connector with this URL and authentication None.

Cursor (~/.cursor/mcp.json), Windsurf, and other clients that take a JSON config:

{
  "mcpServers": {
    "purasim": { "url": "https://api.purasim.com/mcp" }
  }
}

VS Code (.vscode/mcp.json):

{
  "servers": {
    "purasim": { "type": "http", "url": "https://api.purasim.com/mcp" }
  }
}

Clients that only speak stdio can use mcp-remote:

{
  "mcpServers": {
    "purasim": { "command": "npx", "args": ["-y", "mcp-remote", "https://api.purasim.com/mcp"] }
  }
}

Tools

Tool	What it does
recommend_plan	Best plan(s) for a trip from its length and expected usage (light, medium, heavy). Accepts one destination or a list of countries for a multi-country trip.
search_plans	Plans for a country, region or global, cheapest first. Filters: data, validity, price, daily plans.
check_coverage	"Does it work in Peru?": every destination that covers a country, with its mobile networks.
get_destination_info	Countries, operators, 4G/5G, validity options and entry price of a destination.
get_plan	Full detail of one plan: data, validity, speed after the daily allowance, networks per country.
list_destinations	All destinations (countries, regions, global) with entry prices.
create_checkout_link	The purasim.com page of a plan with the plan preselected. No order is placed.

Every tool accepts locale (en, es, de, fr, it, pt, nl, pl, cs, da, no, sv, ro, tr, ar, he, id, ja, ko, th, zh) for the language of the store pages and country names, and currency (USD, EUR, GBP) for prices. Destinations can be given in any of those languages, as ISO codes ("JP") or as regions ("Europe", "Balkans", "Global").

Example questions

• "I'm going to Japan for 10 days and use a lot of maps and Instagram. Which eSIM should I get?"
• "Two weeks in Spain, Portugal and Morocco. Is there one eSIM that covers all three?"
• "Does a PuraSIM eSIM work in Peru, and on which networks?"
• "Cheapest eSIM for the USA with at least 5 GB for a week, in euros."

What the plans are

Prepaid, data-only eSIMs (no phone number), delivered by email with a QR code and installed on any eSIM-compatible, carrier-unlocked phone. Check if your phone supports eSIM. Prices on purasim.com may be shown in the shopper's local currency at checkout.

Privacy

The server needs no account and receives no personal data: only the arguments of each tool call (destination, trip length, filters). Links carry a source tag so PuraSIM can count visits that come from AI assistants.
