LexAtlas

MCP

Connect to your AI

LexAtlas is a remote MCP server. Give your AI client one address, sign in once, and it can search laws, read texts and check citations.

The address

https://api.lexatlas.creatora.app/mcp

Streamable HTTP. Sign-in is OAuth 2.1 with discovery, dynamic client registration and PKCE (S256).

Any MCP client that supports OAuth 2.1 can connect the same way.

What you will see

  1. Your client opens the LexAtlas sign-in page in your browser.
  2. Enter your email and the code we send you.
  3. Review what the client asks for and approve it.
  4. Back in the client, the 10 LexAtlas tools appear and are ready to use. The list is on the MCP page.

Claude (web and desktop)

  1. In Claude open Customize → Connectors and choose Add custom connector.
  2. Enter a name and paste the address above.
  3. Press Add, then sign in to LexAtlas when asked.

Anthropic’s help article lists custom connectors on the Free (one connector), Pro, Max, Team and Enterprise plans.

ChatGPT

  1. Turn on developer mode and create an app for a remote MCP server.
  2. Paste the address above and choose OAuth as the authentication.

Cursor

  1. Add the block below to mcp.json (project .cursor/mcp.json or the global file).
  2. Cursor shows the server as needing sign-in; follow the link to LexAtlas in your browser.
{
  "mcpServers": {
    "lexatlas": {
      "url": "https://api.lexatlas.creatora.app/mcp"
    }
  }
}

Gemini CLI

  1. Add the block below to settings.json (user or project).
  2. Gemini CLI starts the OAuth sign-in in your browser when the server asks for it; the docs describe the commands.
{
  "mcpServers": {
    "lexatlas": {
      "httpUrl": "https://api.lexatlas.creatora.app/mcp"
    }
  }
}

With an API key instead

For a client without OAuth support, send a key in a header on every request to the same address:

X-API-Key: lxa_…

Authorization: Bearer lxa_… works as well. Create keys in your account under API keys.

Pricing

Each tool call counts as a request against your free monthly allowance and then your balance. See Pricing.

Sanctions data

Name-screening aid, not a legal determination. Every result is a possible match (candidate) against the published lists named in `sources`: it does not establish that a person or entity is the one listed, and the absence of a result does not establish that they are not listed. Lists change between updates; confirm against the official source before acting. Not legal advice.

If a result is about you and it is not you, report it: https://api.lexatlas.creatora.app/v1/sanctions/dispute or the form in your account. We respond within 10 working days.
