update_language · Tolgee MCP: Risk & Policy

WHAT IT DOES

What update_language does on Tolgee

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

WHY IT NEEDS A POLICY

Why update_language needs a policy

This tool modifies language properties within a localization project. Write operations typically have medium severity since they can corrupt or alter project data, but the changes are reversible (language properties can be updated again). It does not delete data (which would be Destructive) or execute arbitrary code (Execute), and affects localization metadata rather than financial operations.

From the tool's definition Tool name 'update_language' and description 'Update a language's properties in a Tolgee project' indicate modification of existing data. The verb 'update' is a classic Write operation that changes language configuration reversibly.
