AI agents invoke token_quant_scores to trigger processes or run actions in Nansen-MCP. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
token_quant_scores can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Get Nansen Score Indicators for a token - quantitative risk and reward signals. Use this tool when assessing a token's risk/reward profile, evaluating buy/sell decisions, or when the user needs quantitative data to make trading decisions. Returns: Token risk/reward indicators as markdown with interpretation guidance. Token info: - Market Cap: Current market cap in USD - Market Cap Group: largecap (>$1B), midcap ($100M-$1B), or lowcap (<$100M) - Is Stablecoin: Whether token is a stablecoin (some indicators don't apply to stablecoins) Fields returned per indicator: - Score: Signal classification (bullish/neutral/bearish for reward; low/medium/high for risk) - Signal: Raw numeric value of the indicator - Percentile: Rank vs same market cap group (0-100%) - Last Trigger: Date when signal was last calculated Indicator types: - Reward Indicators: price-momentum, funding-rate, chain-fees, chain-tvl, protocol-fees, trading-range - Risk Indicators: btc-reflexivity, liquidity-risk, token-supply-inflation, concentration-risk, cex-flows Notes: - Not all indicators available for every token/chain combination - Percentile compares against same market cap group (largecap >$1B, midcap $100M-$1B, lowcap <$100M). It is categorised as a Execute tool in the Nansen-MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Nansen- MCP server in PolicyLayer and add a rule for token_quant_scores: 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.
token_quant_scores is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the token_quant_scores 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 token_quant_scores. 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.
token_quant_scores 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.
