text_transform · UnClick MCP: Risk & Policy

WHAT IT DOES

What text_transform does on UnClick

AI agents invoke text_transform to trigger actions in UnClick. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

PARAMETERS

Parameter	Type	Required	Description
`text`	string	Yes
`transform`	string	Yes	uppercase, lowercase, titlecase, slug, reverse, etc.

Parameters from the server's own tool schema.

WHY IT NEEDS A POLICY

Why text_transform needs a policy

The tool processes and transforms text through various operations (uppercase, lowercase, title case, slug). It executes a transformation on input data rather than purely reading or writing stored data. The blast radius is very low as it only manipulates text strings with no external side effects or persistence implied.

From the tool's definition 'Transform text (uppercase, lowercase, title case, slug, etc.)' — applies a transformation operation to input text

Verdict

text_transform Rate-limited

text_transform stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
