send_feedback · Mementos MCP: Risk & Policy

WHAT IT DOES

What send_feedback does on Mementos

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

WHY IT NEEDS A POLICY

Why send_feedback needs a policy

Sending feedback creates/submits a new record or message to the service. It is a write operation with minimal blast radius — it does not delete data, execute code, or involve finances. Confidence is slightly reduced because the description is brief and does not detail what data is written or where.

Verdict

send_feedback Rate-limited

send_feedback 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.
