GTO Lab
New — connect your AI

Use GTO Lab from your AI assistant

GTO Lab plugs into AI assistants like Claude and Cursor, so you can ask poker questions in plain English and get answers straight from the solver — the same Deep CFR strategy that powers this site. No coding required: paste one link into your app and you're connected.

It works through MCP (Model Context Protocol), the standard way AI apps connect to outside tools.

What you can ask

Once connected, your assistant can answer questions like these by calling the solver directly:

  • “I have As Ks in the small blind — what's the GTO play?”
  • “On J♥ 7♣ 2♠ after I raise and get called, how often should I c-bet?”
  • “Show me the big blind's calling range facing a small-blind open.”

Under the hood it exposes two tools — get_gto_strategy (the best action mix at one decision) and get_range_grid (the full 13×13 starting-hand chart). Your assistant picks the right one automatically.

Quick connect

The address of the GTO Lab server is a single link. Copy it — you'll paste it into your AI app below.

GTO Lab MCP server URL
https://gto-thingy.vercel.app/api/mcp

Claude Desktop

  1. Open Settings → Connectors (or Developer).
  2. Choose Add custom connector and paste the URL above.
  3. Save, then start a new chat and ask a poker question.

Cursor, Windsurf, and other config-file apps

Add GTO Lab to the app's MCP config (in Cursor: Settings → MCP → Add new server):

{
  "mcpServers": {
    "gto-lab": {
      "url": "https://gto-thingy.vercel.app/api/mcp"
    }
  }
}

Claude Code (terminal)

Run one command:

claude mcp add --transport http gto-lab https://gto-thingy.vercel.app/api/mcp

App only supports “command” servers?

Some older apps can't take a URL directly. Use this bridge config instead — it needs Node.js installed:

{
  "mcpServers": {
    "gto-lab": {
      "command": "npx",
      "args": ["mcp-remote", "https://gto-thingy.vercel.app/api/mcp"]
    }
  }
}

Good to know

  • It's free. The hosted server is shared and rate-limited (about 30 requests per minute) so everyone gets a turn.
  • Heads-up, 100 big blinds. The solver covers 1-v-1 No-Limit Hold'em with ½-pot, pot, 2×-pot and all-in bet sizes — the same model as the rest of this site.
  • Your prompts aren't stored. Each request is answered and forgotten.

Run your own (developers)

Want higher limits or to run it locally? The server is open source — host your own on Vercel, or run it over stdio from a clone. Full instructions, including the two tools' exact inputs:
