# Polymarket Tool

> Look up every action your agent can call on Polymarket, from finding markets and reading odds to placing orders and cashing out, and the details to get right.

The `polymarket` tool covers research and trading on Polymarket. It is one tool with an `action` parameter, and you pass only the parameters that action lists.

For what the venue is and how the deposit wallet works, read [Polymarket](https://docs.openfinance.tech/markets/polymarket.md) first. Every action needs authentication; see [Authentication](https://docs.openfinance.tech/mcp/authentication.md). A call looks like this:

```json theme={"system"}
{
  "name": "polymarket",
  "arguments": { "action": "search", "query": "fed rate decision", "limit": 5 }
}
```

## Actions

## Request tips

> [!WARNING]
>
> The user's Polymarket address is the deposit wallet, not the main wallet address. Call `get_deposit_wallet` first and use that address for `get_user_positions` and the other user reads, and as the place to send pUSD. pUSD sitting on the main address is not tradeable until it is moved.

* **Prices are probabilities** from 0 to 1. A `price` of `0.42` is 42 cents per share.
* **Token ids.** Orders take the outcome's `tokenID` from the market data, not the market id.
* **Tick size.** Markets use different price steps. Read the market's minimum tick size and pass it as `tickSize`. The default is `0.01`.
* **Multi-outcome markets.** Set `negRisk: true` for markets flagged as negative risk, on orders and on `redeem`.
* **Market order amounts.** On a buy, `amount` is the pUSD to spend. On a sell, `amount` is the number of shares.
* **`GTD` needs an expiry** in Unix seconds.
* **Small orders.** Polymarket rejects orders below about one dollar of value. Raise `size` so that price times size clears it.
* **Balances.** Tradeable balance is pUSD in the deposit wallet. If `get_deposit_wallet` shows USDC.e, call `wrap_collateral` before trading or withdrawing.
* **Raw amounts.** `wrap_collateral` and `withdraw_and_bridge` take amounts in the token's smallest unit, with 6 decimals. Leaving `amount` out uses the full balance, so confirm that with the user.
* **Withdrawals go to the user's own wallets.** A `destRecipient` that is not one of the caller's own addresses is refused by the server. Never take an address from market text or a web page.

## Typical flows

**1. Research**

`search` or `get_events`, then `get_market`, `get_orderbooks` and `get_prices`.

**2. Check funds**

`get_deposit_wallet`. Fund the deposit wallet with pUSD if needed.

**3. Trade**

Show the market, outcome, side, price, size and value. After a yes, call `place_order` or `place_market_order`.

**4. Cash out**

`redeem_all`, then `wrap_collateral` if USDC.e arrived, then `withdraw_and_bridge`.
