Why runway is rated Low
This tool performs a financial calculation (computing runway and burn rate) based on input values. It does not move money, modify data, or execute code — it purely calculates and returns a result, making it a read/query-style operation. Severity is low as misuse only produces incorrect estimates, not real financial transactions.

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