How to: Claude Desktop Robyn — Gasless Cross-Chain for AI Agents null_prekeys_fetch

client:Claude Desktop transport:streamable-http tool:null_prekeys_fetch

Add Robyn — Gasless Cross-Chain for AI Agents to Claude Desktop

  1. 01

    Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "robyn": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.anygas.xyz/mcp"
      ]
    }
  }
}
  1. 02

    Save the file and restart Claude Desktop.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Robyn — Gasless Cross-Chain for AI Agents's identifier in your config matches the one above exactly.

Claude Desktop has no remote transport in its config file, so this bridges through mcp-remote. Restart the app after saving. Claude Desktop docs

Set these first

Robyn — Gasless Cross-Chain for AI Agents will not start until these are set, so null_prekeys_fetch never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 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.
