What remember does on Claude Memory

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

Medium Risk

Why remember needs a policy

This tool creates or modifies data (facts stored in Supabase) in a reversible manner—facts can be updated, overwritten, or deleted via sibling tools like 'forget'. It does not execute arbitrary code, delete irreversibly, move money, or retrieve data.

From the tool's definition Tool name 'remember' combined with description 'Save an important fact to persistent memory' indicates creation and modification of data in Supabase backend. The verb 'Save' is characteristic of Write operations.

Documented attack patterns abuse exactly the kind of access remember gives an agent:

How to control remember

PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Memory, and nothing reaches the server without passing your rules. This is the rule we recommend for remember:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "remember": {
      "limits": [
        {
          "counter": "remember_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

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.

  1. Create a free account and register Claude Memory — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about remember

What does the remember tool do? +

Save an important fact to persistent memory. Use when the user says. It is categorised as a Write tool in the Claude 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 remember? +

Register the Claude Memory 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 Claude Memory. 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 Claude Memory MCP server (jordanl61/claude-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Claude Memory tool call.

Start from Claude Memory, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.

Free to start. No card required.
