AI agents call help to retrieve information from SLayer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Help functions are standard informational tools that retrieve documentation or usage information. With an empty description, this is likely a benign Read operation that provides guidance to users. The context of an agent-native semantic layer suggests this retrieves query syntax or usage documentation. No indication of data modification, deletion, execution, or financial operations.
From the tool's definition Tool name 'help' with empty description suggests a documentation or assistance function typical of help/info commands that retrieve information without side effects.
Documented attack patterns abuse exactly the kind of access help gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SLayer, and nothing reaches the server without passing your rules. This is the rule we recommend for help:
{
"version": "1",
"default": "deny",
"tools": {
"help": {}
}
}help is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

help. It is categorised as a Read tool in the SLayer MCP Server, which means it retrieves data without modifying state.
Register the SLayer MCP server in PolicyLayer and add a rule for help: 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 SLayer. Nothing to install.
help 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 help 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 help. 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.
help is provided by the SLayer MCP server (motleyai/slayer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SLayer, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
