2. Install Parlay in your client

Pick the assistant you already use. Each tab shows the exact one-time setup.

Add the MCP connector in Claude -> Settings -> Connectors -> Add custom connector.

https://mcp.parlay.run/mcp

Requires Claude Pro, Max, Team, or Enterprise. A browser tab opens for OAuth the first time you call a tool.

In ChatGPT, open Settings → Apps → Advanced settings and toggle Developer mode ON.
Back in Settings → Apps, click Create app next to Advanced settings.
Name: Parlay — MCP URL: https://mcp.parlay.run/mcp
The OAuth popup will appear on first query; authorize with the same Google account you signed up with.

Requires ChatGPT Plus, Pro, Team, Business, Enterprise, or Edu. Free plans do not support custom MCP connectors.

One command from your terminal:

gemini extensions install https://github.com/parlay-run/parlay-mcp

A browser tab opens automatically for OAuth the first time you call a tool.

Generate a personal access token from Settings -> Tokens, then run these commands from your terminal:

git clone https://github.com/parlay-run/parlay-mcp.git
openclaw plugins install ./parlay-mcp
export PARLAY_TOKEN=parlay_pat_xxxxxxxxxxxx
openclaw gateway restart

Use your real token value for PARLAY_TOKEN.

Parlay works with any MCP-compatible client, including Cursor, Codex, Windsurf, Perplexity, and Claude Code. Drop the URL into your client's MCP connector settings.

MCP Server URL: https://mcp.parlay.run/mcp
Transport: streamable HTTP
Auth: OAuth 2.1 — browser opens on first connect

3. Verify the connection

Before running real queries, sanity-check that Parlay is connected. Ask your assistant:

List the prediction market venues Parlay currently covers.

You should see Polymarket, Kalshi, Limitless, and Manifold returned in a structured response. If you don't, see Troubleshooting.

4. Run your first real query

Parlay's superpower is cross-venue comparison. Try:

Compare prices on the next Fed rate decision across Polymarket and Kalshi. Where is the biggest spread?

Then ask for a short brief:

Write a short market brief on that comparison and include source links.

Parlay returns structured data your AI client can cite, chart, and reason over.
