RECOMMENDED RULE

The rule that runs get_context safely

get_context Allowed

get_context 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 Metis Public Health, apply this rule, and every get_context call is checked against it from then on.
