AI agents call list_code_artifacts to retrieve information from Forgetful without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries code artifacts from the knowledge base without modifying, deleting, or executing anything. The absence of a description reduces confidence slightly, but the clear semantic meaning of 'list_' combined with the server's stated purpose of 'storage and retrieval' and the presence of separate delete operations on the same server strongly indicates a simple Read operation.
From the tool's definition Tool name 'list_code_artifacts' indicates a retrieval/query operation with no modification capability. The 'list' verb is characteristic of Read operations (no side effects).

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 list_code_artifacts:
{
"version": "1",
"default": "deny",
"tools": {
"list_code_artifacts": {}
}
}list_code_artifacts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_code_artifacts. It is categorised as a Read tool in the Forgetful MCP Server, which means it retrieves data without modifying state.
Register the Forgetful MCP server in PolicyLayer and add a rule for list_code_artifacts: 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.
list_code_artifacts is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_code_artifacts 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 list_code_artifacts. 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.
list_code_artifacts 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.
