save_translations · Paraglide MCP: Risk & Policy

WHAT IT DOES

What save_translations does on Paraglide

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

WHY IT NEEDS A POLICY

Why save_translations needs a policy

save_translations modifies translation data for a specific locale by persisting changes to the project, which is a write operation. It does not delete data (would be Destructive), execute arbitrary code (would be Execute), nor handle financial transactions (would be Financial).

From the tool's definition Tool description states 'write them to the project' and 'Save translated messages', indicating creation/modification of translation data files.

save_translations Rate-limited
