What fund_holdings does on ScorpTech x402 API
AI agents call fund_holdings to retrieve information from ScorpTech x402 API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
fund | string | Yes | Mutual fund or ETF ticker, SEC series id (S000002839) or class id (C000092055). Aliases: ticker, series |
limit | integer | — | Top holdings to return by absolute USD value (1-100, default 25) |
Parameters from the server's own tool schema.
Why fund_holdings is rated Low
Even though fund_holdings only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs fund_holdings safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For fund_holdings, this is the rule to start with:
fund_holdings is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every fund_holdings call is checked against it from then on.
