shibaSIM for AI assistants

Connect

Endpoint: https://shibasim.net/mcp (Streamable HTTP, MCP protocol 2025-06-18). No account or API key. Server metadata: /mcp-server.json.

Add it as a remote MCP server in your client, for example:

{
  "mcpServers": {
    "shibasim": {
      "type": "http",
      "url": "https://shibasim.net/mcp"
    }
  }
}

Or try it from a terminal:

curl -s https://shibasim.net/mcp \
  -H 'content-type: application/json' -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"search_plans","arguments":{"destination":"Japan","limit":3}}}'

Tools

• list_destinations: Destinations with eSIM plans: code, name, ISO country codes, plan count and cheapest USD price.
• search_plans: Plans for one destination. Filters: minimum data (GB), minimum validity (days), maximum price (USD), per-day or total data, 5G, hotspot. Sort by cheapest or value, up to 30 results.
• get_plan: One plan by id: data, validity, daily cap and reduced speed, covered countries, hotspot, top-up availability, network facts verified on shibaSIM, USD price and checkout link.

What to know

• Read-only: the tools cannot place orders and expose no customer, order or account data.
• Prices are in USD and come from the same catalog as our plan pages and checkout. Plan details are listed information: confirm final terms at checkout. JCB cards are not supported.
• Each plan has a checkout link that opens its shibaSIM page. Links carry a source label so we can see AI-assistant traffic; they never change the price.
• Fair use: up to 60 requests per minute per IP, responses are cached for about 10 minutes.
