Description, as the server wrote it
Mid-price path per Polymarket market for backtesting, resampled to a fixed interval and bounded to each market's own lifetime so post-settlement books cannot leak in as risk-free fills. Returns {interval_seconds, markets:{<market_id>:{points:[[ts_ms, price_up, coin_price], …]}}} — up to 1000 points per market. Pass 1 to 50 market ids from polymarket_search_markets. History is bounded by the plan window and the interval floor by plan; both fail closed rather than silently coarsening.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
OHLCV price bars for US equities and ETFs, Binance spot pairs, and perpetual futures. One minute is the finest resolution; 5Min, 15Min, 1Hour and 1Day are rolled up from it and say so with `derived`. Spell a crypto pair the way the venue does (BTCUSDT, not BTC) and a perpetual with a .P suffix (BTCUSDT.P) — spot and perp are different instruments at different prices. BTCU, ETHU and WLDU are each both a US ETF and a Binance pair, and resolve to the equity — pass venue=binance to reach the pair instead. Optional `venue` selects the market explicitly: us-equities, binance (spot) or binance-futures (perpetuals). Bounded by the same plan history window as every other read (403 HISTORY_LIMIT_EXCEEDED past it); the plan also sets how many symbols one request may carry.

Description, as the server wrote it
Paid data plan required. Return every active Polymarket market across all categories, not only crypto. AI execution credits do not unlock this export. The text result is one LLM-readable line per market: MARKET_NAME | OUTCOME PRICES | DEADLINE | MARKET_ID. The sweep fails closed if complete pagination cannot be verified and includes timestamp, count, source-page count, and SHA-256.

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
