Add worldwide eSIM — one eSIM for the whole world to Zed

  1. 01

    Open ~/.config/zed/settings.json and merge this in. Keep any servers already there.

{
  "context_servers": {
    "esim-catalog": {
      "url": "https://worldwideesim.com/wp-json/worldwideesim/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

    size_my_trip is surfaced in the client's prompt or command menu. Unlike a tool, you invoke it deliberately — Zed will not call it for you.

  3. 04

    If it does not appear, check that worldwide eSIM — one eSIM for the whole world is connected and that you are looking at its prompts rather than its tools.

Merge this into your existing settings object — do not replace the file. Zed docs

Same prompt, other clients

Read from the server itself, by connecting to it and calling prompts/list on 28 October 2026. A listing does not declare its prompts, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each prompt's arguments.
