Agent builder

Switch on the pieces. Read the prompt. Send it to Claude.

Each switch is a strategy fragment or a risk rule written with the right oddsrail tools in the right order. Press Run and they execute on our server against the live book, into a paper ledger for this browser, in seconds. No account, no install, no key. Or take the same pieces as a prompt into your own Claude.

What the switches cannot do

Stop losses are review rules, not orders. Polymarket has no stop orders. A stop here means: at each review, if the mark is below your threshold, sell at the bid. Between reviews nothing protects you.
Paper is an upper bound. Fills are simulated from the live book with no queue, no impact and no fees, and paper does not pay out at resolution; it marks at the mid.
Two-sided quoting looked fine on paper for us too. The maintainer's own market-making engine lost about 4.5 cents per share on markout live at small size. That fragment ships with the warning inside the prompt.
One pass per message. Claude runs the prompt once. For an agent that keeps going, run the same prompt on a schedule with the self-hosted plugin, or ask Claude for another pass. In Claude Code: claude mcp add --transport http oddsrail https://mcp.oddsrail.app/mcp.
