Slashtel MCP server
Travel eSIMs for 190+ countries and mobile top-ups for 100+ countries, from inside any AI assistant.
Slashtel is a remote Model Context Protocol server. There is nothing to install and no API key. Point your MCP client at the endpoint and the assistant can look up live plans, compare prices and hand the traveller a checkout link. Payment happens on slashtel.com; the assistant never touches card details.
https://slashtel.com/api/mcp
Transport: Streamable HTTP. Authentication: none. All tools are read-only.
Where it is listed
Run locally (stdio)
For clients that only take local servers, this repo includes a small stdio server that proxies to the hosted endpoint. No API key and no account.
{
"mcpServers": {
"slashtel": { "command": "npx", "args": ["-y", "github:KTUKIT/slashtel-mcp"] }
}
}
Or with Docker: docker build -t slashtel-mcp . && docker run -i --rm slashtel-mcp. Set SLASHTEL_MCP_URL to use a different endpoint.

Example conversation
User: I'm flying to Turkey for ten days, need about 5GB.
Assistant calls get_esim_plans with destination: "TR", min_gb: 5, min_days: 10, picks the best fit, then calls create_checkout_link with the plan_id.
Assistant: Turkey 5GB for 15 days is $X.XX. Here is the checkout link. Install it on Wi-Fi before you fly and it starts when you land. Your own SIM stays on for calls and bank codes.
User: Send ₹299 to my mum's Airtel number, +91 12345 67890.
Assistant calls get_topup_plans with the number, shows the options, then create_checkout_link with type: "topup".
How it behaves
- Prices are live and in USD, all fees included. Quote them exactly as returned.
- eSIMs are data only. The traveller keeps their own number for calls, texts and bank codes.
- Validity starts when the eSIM first connects at the destination, so it can be bought and installed before travel.
- The QR code arrives by email within minutes of payment. Top-ups land on the number in about a minute.
- No tool ever charges anything. Checkout is on slashtel.com only.
