Attacks that exploit this kind of access
The rule that runs getEMA safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Financial Modeling Prep, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For getEMA, this is the rule to start with:
getEMA 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 Financial Modeling Prep, apply this rule, and every getEMA call is checked against it from then on.
