Common questions

Is Lawstronaut safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Lawstronaut MCP

Connect lawstronaut to Claude, ChatGPT, Cursor, and any AI agent that speaks the Model Context Protocol. Connect your AI to 50+ million laws and court cases!

Authentication . Setup · Tools

What is this?

Lawstronaut is the infrastructure layer that connects AI agents and software to millions of legal documents across 150+ jurisdictions, structured legal data, continuously updated, and ready to use via MCP.

Authentication

Production MCP server: `https://mcp.lawstronaut.com`

Transport: MCP over Streamable HTTP (POST /).

Public server card (tool listing, no auth): https://mcp.lawstronaut.com/.well-known/mcp/server-card.json

Lawstronaut MCP supports Bearer token and OAuth 2.0 (client_id + client_secret). A paid subscription is required.

Method	Best for	Tool listing	Tool calls
Bearer token	CLI, scripts, clients without OAuth	No auth required	`Authorization: Bearer`
OAuth 2.0	Cursor, VS Code, Claude, publishing platforms	No auth required	OAuth access token (auto-managed by client)

Get client ID, secret, or bearer token

Visit lawstronaut.com and purchase a subscription.
Log in to the developer portal.
Open MCP server access from the Home menu.
Create a client ID + client secret (OAuth) or a bearer token.

Option A — Bearer token

Use the bearer token from MCP server access:

Authorization: Bearer <your-token>

Set it in your environment:

export LAWSTRONAUT_MCP_BEARER_TOKEN="your-token-here"

Example configs: cursor-mcp.json, vscode-mcp.json, claude-code.mcp.json.

Option B — OAuth 2.0 (client_id + client_secret)

Use the client_id and client_secret created under MCP server access in the developer portal.

Endpoint	URL
MCP server	`https://mcp.lawstronaut.com`
Authorization	`https://mcp.lawstronaut.com/oauth/authorize`
Token	`https://mcp.lawstronaut.com/oauth/token`
OAuth discovery	`https://mcp.lawstronaut.com/.well-known/oauth-authorization-server`
Protected resource	`https://mcp.lawstronaut.com/.well-known/oauth-protected-resource`

Flow: response_type=code → redirect with code → exchange at /oauth/token with grant_type=authorization_code, client_id, client_secret, code, and redirect_uri.

Clients that support MCP OAuth discovery only need the server URL — they handle the flow using your registered client_id / client_secret.

Example configs: cursor-mcp-oauth.json, vscode-mcp-oauth.json.

Setup

Pick your client, paste the config, and authenticate with your lawstronaut account. Most clients open a browser window for OAuth the first time an agent uses a lawstronaut tools.

Cursor

Bearer token

Copy cursor-mcp.json to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global).
Export LAWSTRONAUT_MCP_BEARER_TOKEN.
Restart Cursor. Check Output → MCP Logs if connection fails.

OAuth

Copy cursor-mcp-oauth.json to .cursor/mcp.json.
Complete the OAuth sign-in when Cursor prompts you (uses your registered client_id / client_secret).

Docs: Cursor MCP.

VS Code (GitHub Copilot agent / MCP)

Bearer token

Copy vscode-mcp.json to .vscode/mcp.json, or merge into your user MCP config.
Run MCP: List Servers and enter your bearer token when prompted.

OAuth

Copy vscode-mcp-oauth.json to .vscode/mcp.json.
Sign in through VS Code when prompted.

Docs: MCP configuration reference.

Claude Code (CLI)

Bearer token — CLI

export LAWSTRONAUT_MCP_BEARER_TOKEN="your-token-here"

claude mcp add --transport http lawstronaut-mcp https://mcp.lawstronaut.com \ --header "Authorization: Bearer $LAWSTRONAUT_MCP_BEARER_TOKEN"

Bearer token — project file

Copy claude-code.mcp.json to .mcp.json in your project root.

OAuth

Add the server URL only and complete OAuth when prompted:

claude mcp add --transport http lawstronaut-mcp https://mcp.lawstronaut.com

Docs: Connect Claude Code to tools via MCP.

Claude Desktop (Anthropic app)

Claude Desktop is oriented toward stdio MCP servers. For this HTTP server, use Cursor, VS Code, or Claude Code, or any host that supports remote Streamable HTTP MCP.

Go to Customize, Connectors, click "+", Add Custom Connector, and fill the dialog:

Other hosts (Continue, Zed, custom agents, etc.)

Any client that supports MCP Streamable HTTP can connect with:

URL: https://mcp.lawstronaut.com
Bearer: Authorization: Bearer
OAuth: use discovery at /.well-known/oauth-authorization-server with your client_id / client_secret
