Parameters from the server's own tool schema.
Why get_datahub_dataset is rated Low
Even though get_datahub_dataset 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 get_datahub_dataset safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Doit, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_datahub_dataset, this is the rule to start with:
get_datahub_dataset 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 Doit, apply this rule, and every get_datahub_dataset call is checked against it from then on.
