Install the extension

v0.18.1

Download the installer on your computer, then open it in Claude Desktop. You can also drag it into Settings → Extensions.

Keep “Paper trading” checked for the first review. This is the extension's default simulation mode; no wallet key is needed to explore the tools. Claude Desktop handles the Python setup.

Claude Code or another MCP client

Install the package in your own Python environment:

pip install oddsrail==0.18.1

For Claude Code, add the local server:

claude mcp add --transport stdio oddsrail -- oddsrail

For another MCP client, use this local stdio command. Its settings format may differ.

{"command":"oddsrail","args":[]}

Share the brief

Review only

Copy this brief into a new Claude chat. It preserves your settings and asks Claude to verify markets and explain the strategy without placing orders.

Review the local setup

Claude checks server_info, reads market data and reports what is ready. Review the findings before any separate trading approval.

The extension provides tools for supervised trading with Claude. It does not automatically run this draft or enforce its strategy, market scope, stop loss or daily loss limit. Your Claude access covers the model usage.

When you are ready for local live trading

First set up a compatible Polymarket trading account with funds and trading approvals. Enter its matching signer private key only in the extension's settings, along with the trading-wallet address if required. Never paste a key into the website or a chat.

Review the extension's local spending controls before unchecking “Paper trading”. The defaults are $25 per order and $100 of submitted notional per server session; the session total resets when the server restarts. These are separate from the requested limits in this brief.

Then verify the account and controls with Claude and separately approve any live order. Installing or copying this brief does not authorize a trade. Hosted agents are still unavailable.
