AI agents call get_secret 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 secret information but does not modify, delete, or execute operations. While secrets are sensitive, the Read category applies to any data retrieval. Severity is low because the tool only fetches metadata/information about a secret rather than executing code or making financial moves.
From the tool's definition Tool name is 'get_secret' with description 'Get information for a specific secret' — the verb 'get' and phrase 'get information' indicate retrieval without modification.
Documented attack patterns abuse exactly the kind of access get_secret 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 get_secret:
{
"version": "1",
"default": "deny",
"tools": {
"get_secret": {}
}
}get_secret is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get information for a specific secret. 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 get_secret: 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.
get_secret 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 get_secret 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 get_secret. 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.
get_secret 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.
Free to start. No card required.
