What list-directory does on Morphik MCP

AI agents call list-directory to retrieve information from Morphik MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why list-directory needs a policy

This tool only retrieves and displays directory contents—a read-only query operation with no side effects. It does not create, modify, delete, or execute anything. The stated purpose is navigation/discovery to support file ingestion workflows. Security controls mentioned in the server description suggest access is already constrained.

From the tool's definition Tool name is 'list-directory' and description states it 'List files and subdirectories in a specified directory' with results marked as [FILE] or [DIR].

Documented attack patterns abuse exactly the kind of access list-directory gives an agent:

How to control list-directory

PolicyLayer is an MCP gateway — it sits between your AI agents and Morphik MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list-directory:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list-directory": {}
  }
}

list-directory is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Morphik MCP — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

It is categorised as a Read tool in the Morphik MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list-directory? +

Register the Morphik MCP server in PolicyLayer and add a rule for list-directory: 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 Morphik MCP. Nothing to install.

What risk level is list-directory? +

list-directory is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list-directory? +

Yes. Add a rate_limit block to the list-directory 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.

How do I block list-directory completely? +

Set action: deny in the PolicyLayer policy for list-directory. 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.

What MCP server provides list-directory? +

list-directory is provided by the Morphik MCP server (morphik-org/morphik-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Morphik MCP tool call.

Start from Morphik MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
