markIncomplete · Todo MCP: Risk & Policy

WHAT IT DOES

What markIncomplete does on Todo

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

WHY IT NEEDS A POLICY

Why markIncomplete needs a policy

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

Verdict

markIncomplete Rate-limited

markIncomplete 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.
