format_convert · AgentOS MCP: Risk & Policy

WHAT IT DOES

What format_convert does on AgentOS

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

WHY IT NEEDS A POLICY

Why format_convert needs a policy

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

format_convert Rate-limited

format_convert 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.
