Claude Desktop Nightbreak Forge fetch_plugin_source_file

How to: Claude Desktop Nightbreak Forge fetch_plugin_source_file

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

Add Nightbreak Forge to Claude Desktop

  1. 01

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

{
  "mcpServers": {
    "forge": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://forge.nightbreak.io/mcp"
      ]
    }
  }
}
  1. 02

    Save the file and restart Claude Desktop.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Nightbreak Forge'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

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 11 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.
