add_server · Remote Terminal MCP: Risk & Policy

WHAT IT DOES

What add_server does on Remote Terminal

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

WHY IT NEEDS A POLICY

Why add_server needs a policy

An AI agent can call add_server faster than any human can review — one bad instruction and it creates or modifies resources in Remote Terminal by the hundred, each call as confident as the last.

Verdict

add_server Rate-limited

add_server 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.
