Store an idea, task, or note in your second brain. Call this automatically whenever the user shares context, goals, decisions, or preferences.
AI agents use remember to create or update resources in Second Brain Cloudflare — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Second Brain Cloudflare environment.
This tool creates and stores user-provided data (notes, ideas, tasks, preferences) in a persistent second-brain system. It modifies state by adding records, making it a Write operation. Severity is medium because misuse could result in storage of incorrect, sensitive, or misleading information that gets recalled later and influences AI decisions, but the data remains reversible (can be deleted via the 'forget' tool).
From the tool's definition Tool description states 'Store an idea, task, or note' which is a create/write operation. The name 'remember' and context of a 'semantic memory layer' indicate data is persisted for later retrieval.
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 Second Brain Cloudflare, 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 an idea, task, or note in your second brain. Call this automatically whenever the user shares context, goals, decisions, or preferences. It is categorised as a Write tool in the Second Brain Cloudflare MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Second Brain Cloudflare 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 Second Brain Cloudflare. 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 Second Brain Cloudflare MCP server (rahilp/second-brain-cloudflare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
