AI agents use remember to create or update resources in Novyx — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Novyx environment.
The name 'remember' strongly implies storing/persisting information to memory, which is a Write operation. The server explicitly advertises 'shared memory' functionality. However, the empty description means we cannot confirm the exact behavior, lowering confidence. Severity is medium since writing to shared memory could affect other MCP clients relying on that context.
From the tool's definition Tool name 'remember' with empty description. Server description mentions 'shared memory' as a core feature.
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 Novyx, 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.

remember. It is categorised as a Write tool in the Novyx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Novyx 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 Novyx. 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 Novyx MCP server (novyxlabs/novyx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
