AI agents call hyperliquid_get_trade_fills to retrieve information from HL Portfolio API without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though hyperliquid_get_trade_fills only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Use this when you need to retrieve recent trade executions (fills) for a Hyperliquid perpetuals account. Returns the most recent trades with full execution details including realized PnL on closed positions. Returns: 1. coin: the perpetual market (BTC, ETH, SOL, etc.) 2. side: buy or sell (A = sell/ask, B = buy/bid) 3. size: position size filled 4. price: execution price 5. fee: trading fee paid in USD 6. closedPnl: realized PnL if the trade closed a position (0 if opening) 7. timestamp: execution time in milliseconds 8. hash: transaction hash for the fill 9. crossed: whether the order crossed the spread (taker) Example output: { fills: [{ coin: "ETH", side: "buy", size: "10.0", price: "3450.50", fee: "0.69", closedPnl: "0.00", timestamp: 1712000000000 }], count: 20 } Use this to analyze a trader's recent activity, calculate realized PnL, evaluate trading frequency, or audit trade execution quality on Hyperliquid. Do NOT use for current positions -- use hyperliquid_get_account_state instead. Do NOT use for open/pending orders -- use hyperliquid_get_open_orders instead. Do NOT use for funding payments -- use hyperliquid_get_user_funding instead. Do NOT use for market-wide whale trades -- use hyperliquid_detect_whale_trades instead.. It is categorised as a Read tool in the HL Portfolio API MCP Server, which means it retrieves data without modifying state.
Register the HL Portfolio API MCP server in PolicyLayer and add a rule for hyperliquid_get_trade_fills: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches HL Portfolio API. Nothing to install.
hyperliquid_get_trade_fills is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the hyperliquid_get_trade_fills rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for hyperliquid_get_trade_fills. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
hyperliquid_get_trade_fills is provided by the HL Portfolio API MCP server (https://hl-portfolio.api.klymax402.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
