WHY IT NEEDS A POLICY

Why update_key needs a policy

This tool modifies existing translation key data reversibly. It is Write category because updates can be undone (reverted to previous values), distinguishing it from Destructive operations. Severity is medium because misconfigured updates could corrupt translation data affecting multilingual applications, but the impact is limited to individual keys and reversible via subsequent updates or version control.

From the tool's definition Tool name 'update_key' and description 'Update an existing translation key' indicate modification of existing data. The server description confirms the API enables 'update' operations on translation keys.

update_key Rate-limited

update_key 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.
