KnowJudges MCP

Add judge research tools directly to an AI assistant.

The remote MCP server exposes six focused tools over Streamable HTTP. Compatible AI clients can discover the tools, validate their inputs, and receive structured, source-linked KYJ results without a custom integration layer.

Shared public allowance

Built for focused research, not bulk extraction

API and MCP requests share one allowance for each public client or network. A request blocked by either window returns HTTP 429.

Hourly
20 requests
Daily
100 requests

Connect

For AI clients with remote MCP support

  1. Open the client's connectors, integrations, or MCP settings.
  2. Add a custom remote MCP server.
  3. Enter https://mcp.knowjudges.com/mcp and choose Streamable HTTP if the client asks for a transport.
  4. No authorization header is required for public access.
  5. Enable the discovered KYJ tools, then run the test prompt below.
{
  "mcpServers": {
    "know-your-judge": {
      "url": "https://mcp.knowjudges.com/mcp"
    }
  }
}

Configuration field names vary by AI product. If your client asks only for a server URL, use the URL above rather than the full JSON example.

Available tools

What the AI can call

  • find_judgesResolve a likely judge and canonical KYJ slug.
  • find_ai_abuse_casesFind up to 10 cases with the judge, court response, source, and a verified official decision link when available.
  • get_judge_profileRetrieve a public profile with sources and scoped findings.
  • get_judge_biographyRetrieve sourced public background facts without behavioral inference.
  • get_courtroom_presentation_rulesFocus on PowerPoint, video, exhibits, demonstratives, and related topics.
  • get_recent_rule_changesRead changes recorded after KYJ change tracking began.

Verify

Use a provenance-aware test prompt

Find the five most recent New York court cases involving fabricated AI-generated legal material. Include the judge, court response, and verified official decision URL when available.

A good response links the actual decision, names the dataset source, and does not infer more than the published case summary.

Request accounting

Plan for more than one MCP request

MCP initialization, tool discovery, and individual tool calls are separate HTTP requests. They all draw from the shared public allowance, as do REST API requests from the same client or network.
