AI agents call get_rpc_proxy_url to retrieve information from Waiaas without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name and prefix 'get_' indicate a read-only retrieval operation returning a URL or configuration value. With an empty description, confidence is reduced, but the naming pattern strongly suggests no data modification, deletion, or external execution occurs.
From the tool's definition Tool name 'get_rpc_proxy_url' suggests retrieval of a URL configuration or endpoint identifier. No description provided to clarify function.
Documented attack patterns abuse exactly the kind of access get_rpc_proxy_url gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Waiaas, and nothing reaches the server without passing your rules. This is the rule we recommend for get_rpc_proxy_url:
{
"version": "1",
"default": "deny",
"tools": {
"get_rpc_proxy_url": {}
}
}get_rpc_proxy_url is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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