AI agents use create_code_artifact 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.
The tool creates code artifacts in a persistent knowledge base. This is a Write operation (creates/modifies data reversibly) rather than Read, Execute, Destructive, or Financial. Severity is medium because misuse could clutter the knowledge base or create malicious code artifacts, but the action is reversible (evidenced by the sibling delete_code_artifact tool).
From the tool's definition Tool name is 'create_code_artifact' with empty description. Sibling tools on this server include 'create_document', 'create_entity', 'create_memory', etc., establishing a pattern of Write operations (create_*) and destructive operations (delete_*).
Documented attack patterns abuse exactly the kind of access create_code_artifact 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_code_artifact:
{
"version": "1",
"default": "deny",
"tools": {
"create_code_artifact": {
"limits": [
{
"counter": "create_code_artifact_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_code_artifact 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_code_artifact. 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_code_artifact: 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_code_artifact 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_code_artifact 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_code_artifact. 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_code_artifact 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.
