RECOMMENDED RULE

The rule that runs get_available_arrays safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CLIO Adios, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_available_arrays, this is the rule to start with:

get_available_arrays Allowed

get_available_arrays is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect CLIO Adios, apply this rule, and every get_available_arrays call is checked against it from then on.
