squish_remember · Squish Memory MCP: Risk & Policy

WHAT IT DOES

What squish_remember does on Squish Memory

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

WHY IT NEEDS A POLICY

Why squish_remember needs a policy

This tool writes (stores) information to a shared memory store that persists across sessions and AI agents. It creates new data reversibly (memories could presumably be deleted), so it falls under Write. The blast radius is medium because a misbehaving agent could pollute shared memory with false or misleading context that affects all downstream AI interactions across tools.

From the tool's definition 'Remember a memory for future context' — creates/stores new data persistently in a shared memory system

Verdict

squish_remember Rate-limited

squish_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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Squish Memory, so you can run agents against it safely.

FAQ

Questions about squish_remember

What does the squish_remember tool do? +

Remember a memory for future context. It is categorised as a Write tool in the Squish Memory MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on squish_remember? +

Register the Squish Memory MCP server in PolicyLayer and add a rule for squish_remember: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Squish Memory. Nothing to install.

What risk level is squish_remember? +

squish_remember is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit squish_remember? +

Yes. Add a rate_limit block to the squish_remember rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block squish_remember completely? +

Set action: deny in the PolicyLayer policy for squish_remember. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides squish_remember? +

squish_remember is provided by the Squish Memory MCP server (michielhdoteth/squish). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
