Why license.medical is rated Low
This tool queries a public healthcare provider registry and returns read-only information. It performs no writes, executions, or financial transactions. The severity is low because it accesses publicly available NPI registry data, though it does aggregate PII-adjacent professional information.
From the tool's definition 'lookup' and 'Returns name, credentials, specialty taxonomies with state license numbers, addresses, phone, identifiers' — purely retrieves data from the NPPES NPI Registry with no side effects

The rule that runs license.medical safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For license.medical, this is the rule to start with:
license.medical 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 Mcp, apply this rule, and every license.medical call is checked against it from then on.
