WHAT IT DOES

What levenshtein_distance does on GadgetHumans API Hub

AI agents call levenshtein_distance to retrieve information from GadgetHumans API Hub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why levenshtein_distance is rated Low

This tool performs a pure mathematical calculation comparing two strings and returning a numeric distance value. It reads input, computes a result, and has no side effects on any data store, system, or external service. Misuse potential is negligible.

From the tool's definition 'Calculate the Levenshtein (edit) distance between two strings' — purely a computational read operation with no side effects

RECOMMENDED RULE

The rule that runs levenshtein_distance safely

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

levenshtein_distance Allowed

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