List all directories that this MCP server is allowed to access for file operations
AI agents call listAllowedDirectories to retrieve information from Pinata MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration information about accessible directories. It has no side effects, does not modify state, does not execute code or commands, and does not move or delete data. It is a simple informational query that fits the Read category. Severity is low because the information disclosed is limited to directory accessibility metadata relevant only to the local MCP server's file operation scope.
From the tool's definition Tool name and description both indicate a listing/querying operation: 'listAllowedDirectories' performs a read-only operation that 'List[s] all directories' without modifying, deleting, or executing anything.
Documented attack patterns abuse exactly the kind of access listAllowedDirectories gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pinata MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for listAllowedDirectories:
{
"version": "1",
"default": "deny",
"tools": {
"listAllowedDirectories": {}
}
}listAllowedDirectories is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all directories that this MCP server is allowed to access for file operations. It is categorised as a Read tool in the Pinata MCP MCP Server, which means it retrieves data without modifying state.
Register the Pinata MCP server in PolicyLayer and add a rule for listAllowedDirectories: 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 Pinata MCP. Nothing to install.
listAllowedDirectories 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 listAllowedDirectories 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 listAllowedDirectories. 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.
listAllowedDirectories is provided by the Pinata MCP server (pinatacloud/pinata-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pinata MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
