WHAT IT DOES

What levenshtein does on Gateway

AI agents use levenshtein to create or update resources in Gateway, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gateway environment.

Parameter	Type	Required	Description
`a`	string	Yes	First string
`b`	string	Yes	Second string

Parameters from the server's own tool schema.

RISK

Why levenshtein is rated Medium

An AI agent can call levenshtein faster than any human can review: one bad instruction and it creates or modifies resources in Gateway by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs levenshtein 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 levenshtein, this is the rule to start with:

levenshtein Rate-limited

levenshtein stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. 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 levenshtein call is checked against it from then on.
