List all folders currently being watched for file changes.
AI agents call list_folders to retrieve information from M I M I R Multi Agent Intelligent Memory & Insight Repository without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about monitored folders, which is a read-only operation with no side effects. The action of listing causes no mutations to data or system state. While it may reveal information about the system's indexing configuration, this is informational rather than impactful, warranting low severity.
From the tool's definition Tool name 'list_folders' and description 'List all folders currently being watched for file changes' indicate a pure query operation that retrieves information without modifying state.
Documented attack patterns abuse exactly the kind of access list_folders gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and M I M I R Multi Agent Intelligent Memory & Insight Repository, and nothing reaches the server without passing your rules. This is the rule we recommend for list_folders:
{
"version": "1",
"default": "deny",
"tools": {
"list_folders": {}
}
}list_folders is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
