MCP Connector

USLege Connector for Claude and other AI assistants

The USLege connector gives AI assistants like Claude secure, real-time access to the USLege legislative intelligence platform. Once connected, you can research and track legislation, committees, votes, statutes, hearing video, and more — directly from a conversation, using your existing USLege account and permissions.

The connector is a remote MCP (Model Context Protocol) server. It exposes the same data and actions available in the USLege web app, scoped to your organization and the states you're authorized for. For an overview of what it does and why, see USLege MCP.

Prerequisites

Paid USLege account

Sign in at app.uslege.ai with a paid account. Free and legacy accounts can connect, but won't have access to any data or actions through the connector.

State access

The connector returns data only for your organization's authorized states. Your existing plan coverage applies.

MCP-compatible client

Claude (claude.ai or Desktop), ChatGPT, Perplexity, Grok, or any other AI assistant that supports remote MCP servers.

Connecting

USLege works with Claude, ChatGPT, Perplexity, Grok, or any other MCP-compatible assistant. Every connection is scoped to one individual USLege login — an active USLege account is required to use it.

MCP Server URL
https://app.uslege.ai/mcp
Transport: Streamable HTTP Authentication: OAuth 2.0

USLege connects to Claude, ChatGPT, Perplexity, Grok, or any other MCP-compatible client. Add it as a remote server using the URL above, or, if your client accepts raw config, this:

{
  "mcpServers": {
    "uslege": {
      "url": "https://app.uslege.ai/mcp"
    }
  }
}

USLege is also an official app in Anthropic's Claude connector directory — search “USLege” inside Claude's connector settings to add it without pasting a URL.

Your assistant never sees your password — authentication happens through USLege's secure OAuth flow, and access can be revoked anytime from your USLege account settings.

Grok

Grok supports custom MCP connectors from grok.com. Once USLege is connected there it is available everywhere you use Grok with the same account.

  1. Go to grok.com/connectors and sign in
  2. Click New Connector
  3. Choose Custom
  4. For Name, enter USLege
  5. For Server URL, enter https://app.uslege.ai/mcp
  6. Click Add Connector
  7. Grok opens a popup to sign you in — authenticate with your USLege account and click Allow
  8. USLege now shows as Added on your connectors page
Popup blockers

Step 07 happens in a popup window. If Grok stays on “Complete authentication in the popup window” and nothing opens, allow popups for grok.com and click Add Connector again.

On a Grok Business or Enterprise plan?

A workspace admin has to provision the connector before you can add it. If you do not see New Connector, ask your admin to enable it, then connect from your own account.

Authentication & security

  • OAuth 2.0 required on every request — unauthenticated requests are rejected.

  • Review or revoke access anytime from USLege account settings or your assistant's connector settings.

Data & privacy

The connector accesses USLege platform data on your behalf. It does not store data in your assistant's memory, chat history, or uploaded files. See our Terms & Privacy Policy for collection, usage and storage, third-party sharing, and retention details.
