rephrase_text · DeepL MCP Server MCP: Risk & Policy

WHAT IT DOES

What rephrase_text does on DeepL MCP Server

AI agents invoke rephrase_text to trigger actions in DeepL MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why rephrase_text needs a policy

rephrase_text triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Verdict

rephrase_text Rate-limited

rephrase_text stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
