AI agents use remember to create or update resources in Celiums Memory — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Celiums Memory environment.
The 'remember' tool creates and modifies persistent data (memories) across sessions and machines. This is a Write operation because it reversibly stores user information with emotional analysis and importance scoring.
From the tool's definition Tool description explicitly states 'Store information in persistent memory' and 'stores the content...updates circadian interaction tracking', indicating data creation/modification with persistent side effects.
Documented attack patterns abuse exactly the kind of access remember gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Celiums Memory, and nothing reaches the server without passing your rules. This is the rule we recommend for remember:
{
"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.

Store information in persistent memory that survives across all sessions and machines. Memories are automatically classified by type (semantic, procedural, episodic) and importance. Use to save facts, preferences, decisions, context, or any information that should be recalled later. Behavior: stores the content with emotional analysis (PAD model), assigns importance score, updates circadian interaction tracking. Scoped to current project by default — use projectId=. It is categorised as a Write tool in the Celiums Memory MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Celiums 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 Celiums Memory. Nothing to install.
remember is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
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.
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.
remember is provided by the Celiums Memory MCP server (terrizoaguimor/celiums-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Celiums 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.
