AI agents call list_deployment_files to retrieve information from eToro MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves structural information about deployment files—a read-only query operation. It has no side effects, does not execute code or commands, does not modify data, and does not delete anything. The blast radius of misuse is minimal, as an AI agent could at most discover the file structure of an existing deployment, which is informational only.
From the tool's definition Tool name 'list_deployment_files' and description 'Get file structure of a deployment' indicate a retrieval operation that queries and returns file metadata without modification or deletion.
Documented attack patterns abuse exactly the kind of access list_deployment_files gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and eToro MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_deployment_files:
{
"version": "1",
"default": "deny",
"tools": {
"list_deployment_files": {}
}
}list_deployment_files 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.
Get file structure of a deployment. It is categorised as a Read tool in the eToro MCP Server MCP Server, which means it retrieves data without modifying state.
Register the eToro MCP Server MCP server in PolicyLayer and add a rule for list_deployment_files: 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 eToro MCP Server. Nothing to install.
list_deployment_files 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_deployment_files 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_deployment_files. 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_deployment_files is provided by the eToro MCP Server MCP server (shlomico-tr/etoroportfoliomcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from eToro MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
