Arena Predictions' sandbox for prediction markets is paper trading at live prices, in paper dollars. Public tools answer without sign-in. Account and market tools ask the person to sign in to Arena the first time. When a bet arrives in words ('chiefs ml', 'kc -3.5'), resolve_market maps it to an instrument id (games not yet started first), and get_game lists every instrument on a game. Store instrument_id, not the Kalshi ticker: every tool that takes an instrument (get_market, get_orderbook, get_orders, get_price_history, get_cross_venue_quotes, find_price_gaps, get_instrument, place_trade)…

- Yes — it answered the hub's last check (checked 4h ago). It answered 99% of checks over the last 30 days.
- Is arena-predictions free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does arena-predictions have?
- 30 tools: sell_trade, get_orders, get_game, get_market, set_privacy, resolve_market, get_orderbook, get_cross_venue_quotes, ….
- Is arena-predictions safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
get_eval_board reads open 4h ago
The public eval board: people and AI models scored on settled public picks, ranked inside rank_basis, never by profit, with the market's own scores and 95% intervals (tied_with_above: the sample does not separate a row from the one above). No sign-in.

Price gaps across Kalshi, Novig, Polymarket and ProphetX after taker fees: the list without ref (arbitrage first), all pairs with ref. A pair buys YES on one venue and NO on another; edge = 1 - cost per $1 contract. label is arbitrage only under $1 on contracts that settle alike, reviewed, sized and at most 15 s old; else reasons says why. Nothing here is risk-free. Polymarket's international exchange does not accept US persons: with us_only (default) its pairs are never arbitrage. full adds legs and caveats. No sign-in.

Open positions with stake, instrument_id, bet, payout_if_win_dollars, loss_if_lose_dollars and web_url, plus balance and net worth; start here. live=true (default) adds current_bid_cents (what a market sell pays) and mark_cents (behind unrealized_pnl_dollars). recently_settled: bets settled in the last 24 hours; tell the person.

{ "type": "object", "properties": {} }arguments 4 linessell_trade changes data unknown never probed
Exit an open position at the bid (current_bid_cents), or rest a limit exit that holds no money. No bid: a market sell cannot. A closed trade answers its terminal state. route=best may split: fills lists each leg. route=kalshi sells at Kalshi's bid. contract_note on every exit of a non-Kalshi fill. dry_run=true sells nothing (a limit exit shows crosses_now). Selling is never gated by a membership. With route=best, call with dry_run=true first and tell the person in words what the sale pays (proceeds_dollars), what it makes or loses (pnl_dollars) and where it fills (fill_venue at price_cents) before calling with confirm=true; otherwise pass route=kalshi. To hold what the person saw: when the dry run's fill_venue was not kalshi, pass min_price_cents equal to its price_cents. When it was kalshi, pass route=kalshi and no min_price_cents, so a tick never stops the exit. confirm=true and a fresh idempotency_key, except dry_run. live=true sells on Kalshi. poly_intl=true sells on Polymarket International (not US). Pass one. Default is paper. This server places paper trades only: a call with live or poly_intl is refused (live_not_hosted).

Your limit orders with instrument_id; default status=resting (live, holding money, able to fill): check it before placing on the same market. cancel_reason says why one ended.

Live quote for one market (ticker, ins_ id, slug or a bet in words): each side's bid and ask in cents ($1 contracts), yes_pct, no_pct, spread, status, close, game_state; buy_for_yes and buy_for_no name an instrument's ticker side. contracts or stake_dollars adds cost and payout. Signed out: an instrument's Kalshi price (signed_in: false).

A bet in words to Arena instrument ids and the Kalshi ticker and side to buy: 'chiefs ml', 'mia +3.5', 'kc mia under 44.5 sunday'. Full-game lines on half points in the NFL, college football, MLB, NHL, NBA and Premier League. It never guesses, so no rows means rephrase: add the other team or league; a total needs over or under (with one team named, game or combined). Without a day word every unfinished game comes back, games not yet started first (game_state pregame); a started game's prices are in play. To hold what the words ask, buy kalshi[].buy_side on kalshi[].ticker, or pass instrument_id with instrument_side = query_side. Store instrument_id as given.

Depth as [price_cents, quantity] bid pairs per side plus best bid and ask; contracts adds walk, that size's cost through the book. Paper fills take the whole size at one price.

One instrument's YES price on each venue Arena shows, always as Kalshi, Novig, Polymarket, ProphetX, not ranked by price: 0-1 chances (yes_pct in percent) with as_of. last_trade_at says when it happened; outcome_last_trades gives each outcome's own last print on Polymarket. Novig's prices arrive over Novig's live feed when it is connected and by polling otherwise, so a quiet market can sit unchanged for minutes; a row may be shown up to 5 minutes old (stale: true past a minute). ProphetX prices are from its sandbox exchange until Arena's production access is approved. When cross_venue is false only Kalshi is listed. Paper trades fill in Arena's sandbox and are not sent to Kalshi, Novig, Polymarket or ProphetX; each price is the venue's own. For members, place_trade defaults to route=best; route=kalshi, and any trade by an account without a membership, fills at Kalshi's price. No sign-in.

Buy YES or NO contracts. Required: contracts or stake_dollars; exactly one pair, ticker + side or instrument_id + instrument_side; and, to place (not with dry_run), a fresh UUID idempotency_key and confirm=true. MARKET fills at the ask now. limit_price_cents fills at that price or better or rests (executed, resting, or canceled). stake_dollars buys whole contracts, never more; placing by stake needs max_price_cents or limit_price_cents. The balance is the limit. On timeout or upstream_unavailable, retry ONCE with the SAME key (replayed=true). Never retry a 4xx. A reused key for a different trade is idempotency_key_reused. get_positions (get_orders for a limit) is ground truth. route=best (default, members) picks the venue. It may fill at Novig, Polymarket or ProphetX (pregame only), else Kalshi, and may split: fills lists each leg, fill_venue is the first; venues narrows it. route=kalshi is one venue. rule_note when the contract differs. dry_run=true places nothing (about 20 a minute). Over the cash: insufficient_balance with details.max_contracts. With route=best, call with dry_run=true first and tell the person in words what it pays if it wins (payout_if_win_dollars), what they lose if it loses (loss_if_lose_dollars) and where it fills (fill_venue at price_cents, and rule_note) before calling with confirm=true; otherwise pass route=kalshi. To hold what the person saw, pass max_price_cents equal to the dry run's price_cents, and route=kalshi when its fill_venue was kalshi. stated_prob_pct (1-99) never changes the fill. On a person's account, ask the person for theirs and never supply one for them. Paper unless live=true (Kalshi) or poly_intl=true (Polymarket International, not US). Pass one. Rules: arena://rules/engine. This server places paper trades only: a call with live or poly_intl is refused (live_not_hosted).

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idcd009bc012519005.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/cd009bc012519005/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
