close_risk · Todos MCP: Risk & Policy

WHAT IT DOES

What close_risk does on Todos

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

WHY IT NEEDS A POLICY

Why close_risk needs a policy

This operation creates or modifies data (changes risk status) in a reversible manner. A closed risk can typically be reopened if needed. While the action affects task/project management state, it is not destructive (no permanent deletion), not financial, and not code execution. It is a state-change write operation on a managed entity.

From the tool's definition Tool performs 'Close a local risk as resolved or accepted' — modifies the state of a risk record by changing its status from open to closed/resolved/accepted.

Verdict

close_risk Rate-limited

close_risk 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.
