WHAT IT DOES

What edit_distance does on UnClick

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

Parameter	Type	Required	Description
`source`	string	Yes	Source string (max 5,000 chars)
`target`	string	Yes	Target string (max 5,000 chars)

Parameters from the server's own tool schema.

RISK

Why edit_distance is rated Medium

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

RECOMMENDED RULE

The rule that runs edit_distance safely

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

edit_distance Rate-limited

edit_distance 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 UnClick, apply this rule, and every edit_distance call is checked against it from then on.
