What nport_fund_holdings does on Livedatalink
AI agents call nport_fund_holdings to retrieve information from Livedatalink 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 | EDGAR series ID, mapped ticker, or fund name (at least 2 characters). |
limit | integer | — | Maximum holdings; default 25. |
Parameters from the server's own tool schema.
Why nport_fund_holdings is rated Low
Even though nport_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 nport_fund_holdings safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Livedatalink, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For nport_fund_holdings, this is the rule to start with:
nport_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 Livedatalink, apply this rule, and every nport_fund_holdings call is checked against it from then on.
