# Lawstronaut MCP Connect [lawstronaut](https://mcp.lawstronaut.com) to Claude, ChatGPT, Cursor, and any AI agent that speaks the [Model Context Protocol](https://modelcontextprotocol.io). Connect your AI to 50+ million laws and court cases!

--- ## 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 1. Visit [lawstronaut.com](https://lawstronaut.com) and purchase a subscription. 2. Log in to the [developer portal](https://dev-portal.filerskeepersapi.co/). 3. Open **MCP server access** from the Home menu. 4. Create a **client ID** + **client secret** (OAuth) or a **bearer token**. lawstronaut logo

### Option A — Bearer token Use the bearer token from **MCP server access**: ```http Authorization: Bearer ``` Set it in your environment: ```bash 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](https://dev-portal.filerskeepersapi.co/). | 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** 1. Copy `cursor-mcp.json` to `.cursor/mcp.json` (project) or `~/.cursor/mcp.json` (global). 2. Export `LAWSTRONAUT_MCP_BEARER_TOKEN`. 3. Restart Cursor. Check **Output → MCP Logs** if connection fails. **OAuth** 1. Copy `cursor-mcp-oauth.json` to `.cursor/mcp.json`. 2. Complete the OAuth sign-in when Cursor prompts you (uses your registered `client_id` / `client_secret`). Docs: [Cursor MCP](https://cursor.com/docs/context/mcp). --- ## VS Code (GitHub Copilot agent / MCP) **Bearer token** 1. Copy `vscode-mcp.json` to `.vscode/mcp.json`, or merge into your [user MCP config](https://code.visualstudio.com/docs/copilot/reference/mcp-configuration). 2. Run **MCP: List Servers** and enter your bearer token when prompted. **OAuth** 1. Copy `vscode-mcp-oauth.json` to `.vscode/mcp.json`. 2. Sign in through VS Code when prompted. Docs: [MCP configuration reference](https://code.visualstudio.com/docs/copilot/reference/mcp-configuration). --- ## Claude Code (CLI) **Bearer token — CLI** ```bash 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: ```bash claude mcp add --transport http lawstronaut-mcp https://mcp.lawstronaut.com ``` Docs: [Connect Claude Code to tools via MCP](https://code.claude.com/docs/en/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: claude

--- ## 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` --- ## Tools - **list_jurisdictions** - List all jurisdictions (countries/states) in the Lawstronaut corpus — call first to get valid ISO codes for other tools -
