remember · Enhanced MCP Server MCP: Risk & Policy

WHAT IT DOES

What remember does on Enhanced MCP Server

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

WHY IT NEEDS A POLICY

Why remember needs a policy

The tool writes data (facts, preferences, notes) to some persistent store. It is reversible in principle (data can be deleted later), so Write is the appropriate category rather than Destructive. The description is truncated, which lowers confidence slightly, but the intent is clearly to store/persist information rather than read or execute anything.

From the tool's definition 'Quickly remember anything - facts, preferences, notes, temporary info' — stores/writes data to persistent memory

Verdict

remember Rate-limited

remember 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.
