remember · memro MCP Server MCP: Risk & Policy

WHAT IT DOES

What remember does on memro MCP Server

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

WHY IT NEEDS A POLICY

Why remember needs a policy

This tool writes new episodic, semantic, or procedural memory entries to persistent storage. It creates data reversibly (memories can be deleted via the sibling 'delete_memory' tool), making it a Write operation. Misuse could lead to storing false or misleading context that influences future AI behavior, hence medium severity.

From the tool's definition 'Store a new memory' — creates new data in persistent storage

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.

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

FAQ

Questions about remember

What does the remember tool do? +

Store a new memory. It is categorised as a Write tool in the memro MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on remember? +

Register the memro MCP Server MCP server in PolicyLayer and add a rule for 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 memro MCP Server. Nothing to install.

What risk level is remember? +

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

Can I rate-limit remember? +

Yes. Add a rate_limit block to the 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 remember completely? +

Set action: deny in the PolicyLayer policy for 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 remember? +

remember is provided by the memro MCP Server MCP server (memrohq/memro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
