add_translation · Lara MCP: Risk & Policy

WHAT IT DOES

What add_translation does on Lara

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

WHY IT NEEDS A POLICY

Why add_translation needs a policy

This tool creates or modifies data in a translation memory system. Adding translations is a reversible operation—entries can be deleted or updated later. The blast radius is medium because a compromised AI agent could pollute translation memories with incorrect entries, causing downstream translation quality issues, but the operation is not irreversible and does not involve financial transactions or code execution.

From the tool's definition Tool description states it 'Adds a translation' which is a create/modify operation. The sibling tools include 'delete_translation' and 'delete_glossary_entry', establishing a pattern where write operations are paired with destructive counterparts.

Verdict

add_translation Rate-limited

add_translation 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.
