AI agents call list_available_methods to retrieve information from DIE MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves metadata about available methods without modifying, executing external operations, or deleting anything. The absence of a description lowers confidence slightly, but the name strongly suggests a non-destructive read operation. Consistent with the server's forensic analysis purpose—listing methods would be an informational/discovery operation.
From the tool's definition Tool name is 'list_available_methods' which indicates listing/querying available operations. No description provided, but the name pattern matches information retrieval semantics (list, show, query).
Documented attack patterns abuse exactly the kind of access list_available_methods gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and DIE MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_available_methods:
{
"version": "1",
"default": "deny",
"tools": {
"list_available_methods": {}
}
}list_available_methods is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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