List documents in a specific folder
AI agents call list_documents to retrieve information from Folder 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 documents in a folder without altering, executing, or deleting any data. It is a straightforward query/listing operation that has no side effects beyond returning information about existing files.
From the tool's definition Tool name 'list_documents' and description 'List documents in a specific folder' indicate a retrieval operation with no modification or deletion capability. Server description confirms 'read' and 'list' operations with 'built-in security validation'.
Documented attack patterns abuse exactly the kind of access list_documents gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Folder, and nothing reaches the server without passing your rules. This is the rule we recommend for list_documents:
{
"version": "1",
"default": "deny",
"tools": {
"list_documents": {}
}
}list_documents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List documents in a specific folder. It is categorised as a Read tool in the Folder MCP Server, which means it retrieves data without modifying state.
Register the Folder MCP server in PolicyLayer and add a rule for list_documents: 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 Folder. Nothing to install.
list_documents 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_documents 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_documents. 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_documents is provided by the Folder MCP server (okets/folder-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Folder, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
