set_all · Mcp Locator MCP: Risk & Policy

WHAT IT DOES

What set_all does on Mcp Locator

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

WHY IT NEEDS A POLICY

Why set_all needs a policy

This tool creates or modifies translation data in multiple locale files reversibly. While it writes to files, the changes are not irreversible (they can be edited or reverted), and there is no data deletion or financial impact. The blast radius is medium because misconfigured translations could break application UI/UX across multiple locales, but data can be recovered.

From the tool's definition Tool description explicitly states 'Set a translation key in multiple locales at once' - a modification operation. Server description confirms it 'lets AI agents read and write locale JSON translation files directly.'

Verdict

set_all Rate-limited

set_all 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.
