AI agents use smart_traders_and_funds_perp_trades to create or modify resources in Nansen-MCP. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call smart_traders_and_funds_perp_trades repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Nansen-MCP.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Get recent Hyperliquid perpetual futures trades from Smart Traders and Funds across all tokens. This tool provides granular smart trader and funds activity. For a big picture view of smart traders and funds activity across all tokens, use token_discovery_screener with onlySmartTradersAndFunds filter. Note: This endpoint is Hyperliquid-only (perpetual futures data). It returns recent trades only (no date filtering available). Columns returned: - Time: Timestamp when the trade occurred (datetime: YYYY-MM-DD HH:MM:SS) - Side: Position direction - Long or Short - Action: Order action - Add, Reduce, Open, Close - Token: Symbol of the perpetual contract - Size: Quantity of the perpetual contract (numeric) - Price USD: Price per token at time of trade (price formatted) - Value USD: Total USD value of the trade (currency formatted) - Trader: Nansen label of the trading address - Tx Hash: Blockchain transaction hash for verification Sorting Options (all fields support "asc"/"desc"): Available for sorting: timestamp, valueUsd, amount, priceUsd Examples: # Get recent smart money perp trades (sorted by value) { "order_by": "valueUsd", "order_by_direction": "desc" } # Filter by action and side { "action": "Open", "side": "Long", "includeSmartMoneyLabels": ["Fund", "All Time Smart Trader"] }. It is categorised as a Write tool in the Nansen-MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Nansen- MCP server in PolicyLayer and add a rule for smart_traders_and_funds_perp_trades: 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 Nansen-MCP. Nothing to install.
smart_traders_and_funds_perp_trades is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the smart_traders_and_funds_perp_trades 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 smart_traders_and_funds_perp_trades. 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.
smart_traders_and_funds_perp_trades is provided by the Nansen- MCP server (nansen-ai/Nansen-MCP). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
