Zed Agentic Kingdoms postcard

How to: Zed Agentic Kingdoms postcard

client:Zed transport:streamable-http tool:postcard

Add Agentic Kingdoms to Zed

  1. 01

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

{
  "context_servers": {
    "agentic-kingdoms": {
      "url": "https://mcp.agentickingdoms.com"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

    Ask for something postcard does. Zed lists the server's tools on connect and calls postcard itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Agentic Kingdoms's identifier in your config matches the one above exactly.

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

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
