WHAT IT DOES

What crow_store_memory does on Crow

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

RISK

Why crow_store_memory is rated Medium

This tool creates new data by writing information to persistent memory storage. It's a write operation (creation of stored data) that is reversible in principle (stored memories can typically be deleted). The blast radius is medium because an AI agent could store false or sensitive information that persists across sessions, potentially influencing future behavior, but it does not execute code or delete data.

RECOMMENDED RULE

The rule that runs crow_store_memory safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Crow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For crow_store_memory, this is the rule to start with:

crow_store_memory Rate-limited

crow_store_memory 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Crow, apply this rule, and every crow_store_memory call is checked against it from then on.
