Use it in a session
Ask Claude to use the tools this server exposes (e.g. list_jurisdictions, list_domains, list_subdomains). It discovers them automatically.

How to install Lawstronaut in Claude DesktopDesktop app (MCP config)

Open your MCP config
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

Add this server

json

{
  "mcpServers": {
    "lawstronaut-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.lawstronaut.com"
      ]
    }
  }
}

Why the wrapper?
This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.
Restart Claude Desktop
The tools appear under the 🔌 menu once the app reloads.

How to install Lawstronaut in CursorAI-first code editor

Create / edit .cursor/mcp.json in your project

json

{
  "mcpServers": {
    "lawstronaut-mcp": {
      "url": "https://mcp.lawstronaut.com"
    }
  }
}

Enable it
Cursor Settings → MCP → toggle the server on. Tools become available to the Composer/Agent.

How to install Lawstronaut in Codex CLIOpenAI coding agent

Add to ~/.codex/config.toml

toml

[mcp_servers.lawstronaut-mcp]
command = "npx"
args = ["-y", "mcp-remote", "https://mcp.lawstronaut.com"]

Why the wrapper?
Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.
Run Codex
Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.
