Struct is designed to work natively with AI tools. Whether you’re building autonomous agents, using an AI coding assistant, or integrating prediction market data into an AI workflow — there’s a first-class path for you.

TypeScript SDK

Type-safe client with full autocompletion.

MCP Server

Connect AI assistants directly to Struct data.

AI Skill

Install via skills.sh for instant access in your agent.

​
TypeScript SDK

The Struct SDK gives you a fully typed client for all Polymarket endpoints. Install it and start querying in seconds. 
npm install @structbuild/sdk

import { StructClient } from "@structbuild/sdk";

const client = new StructClient({ apiKey: "YOUR_API_KEY" });

const markets = await client.markets.getMarkets();

const event = await client.events.getEventBySlug({ slug: "us-presidential-election" });
Every method returns fully typed responses — no manual type definitions, no guessing field names.

SDK Reference

Full documentation, examples, and source code.

​
MCP Server

Struct exposes a Model Context Protocol (MCP) server that lets AI assistants query prediction market data directly. The MCP server is available at api.struct.to/mcp and supports two authentication methods.

​
OAuth (for AI assistants)

For AI assistants like ChatGPT and Claude that support OAuth-based MCP connections, simply connect using the MCP URL: 
https://api.struct.to/mcp
The assistant will handle the OAuth flow automatically — no API key management needed.

​
API Key (for backend agents)

For backend AI agents and programmatic access, connect to the MCP server directly with your API key: 
{
  "mcpServers": {
    "struct": {
      "url": "https://api.struct.to/mcp?api_key=YOUR_API_KEY"
    }
  }
}
Once connected, your AI agent can search markets, pull real-time prices, look up trader positions, and more — all through natural language.

​
AI Skill

Install the Struct skill to give any Claude Code agent instant access to Struct’s Polymarket data. 
npx skills add structbuild/struct-skill
Once installed, the agent can query markets, events, trades, and positions without any additional setup.
