strings_update_project · Phrase MCP: Risk & Policy

WHAT IT DOES

What strings_update_project does on Phrase

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

WHY IT NEEDS A POLICY

Why strings_update_project needs a policy

The tool creates or modifies project data reversibly within the Phrase Strings localization platform. Updates to localization projects could affect translations, project metadata, and team configurations. While reversible (changes can be undone/re-updated), the blast radius is significant—an AI agent with incorrect parameters could modify critical project settings affecting the entire localization workflow.

From the tool's definition Tool name contains 'update' and description states 'Update an existing project in Phrase Strings.' This modifies existing data (project settings/configuration) in a localization management system.
