AI agents use create_memory to create or update resources in Forgetful — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Forgetful environment.
This tool creates data in a persistent knowledge base, which is reversible and modifiable—characteristic of Write operations. Without an explicit description, confidence is moderate (0.75).
From the tool's definition Tool name 'create_memory' on a storage/retrieval MCP server; sibling tools include create_document, create_entity, create_project, all Write-class operations. The name prefix 'create_' indicates data creation.
Documented attack patterns abuse exactly the kind of access create_memory gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Forgetful, and nothing reaches the server without passing your rules. This is the rule we recommend for create_memory:
{
"version": "1",
"default": "deny",
"tools": {
"create_memory": {
"limits": [
{
"counter": "create_memory_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_memory 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.

create_memory. It is categorised as a Write tool in the Forgetful MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Forgetful MCP server in PolicyLayer and add a rule for create_memory: 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 Forgetful. Nothing to install.
create_memory 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 create_memory 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 create_memory. 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.
create_memory is provided by the Forgetful MCP server (scottrbk/forgetful). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
