Authentication . Setup · Tools
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.
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.
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.
Use the client_id and client_secret created under MCP server access in the developer portal.
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.
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.
Bearer token
cursor-mcp.json to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global).LAWSTRONAUT_MCP_BEARER_TOKEN.OAuth
cursor-mcp-oauth.json to .cursor/mcp.json.client_id / client_secret).Docs: Cursor MCP.
Bearer token
vscode-mcp.json to .vscode/mcp.json, or merge into your user MCP config.OAuth
vscode-mcp-oauth.json to .vscode/mcp.json.Docs: MCP configuration reference.
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
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:
