List all node9 approver channels and their current enabled/disabled state.
AI agents call node9_approver_list to retrieve information from Node9-Proxy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and displays the current state of approver channels. It does not create, modify, delete, or execute any operations. The read-only nature and informational purpose make this a low-severity Read operation suitable for security governance introspection.
From the tool's definition Tool name includes 'list' and description states 'List all node9 approver channels and their current enabled/disabled state' — a pure query operation that retrieves status information without modification or side effects.
Documented attack patterns abuse exactly the kind of access node9_approver_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Node9-Proxy, and nothing reaches the server without passing your rules. This is the rule we recommend for node9_approver_list:
{
"version": "1",
"default": "deny",
"tools": {
"node9_approver_list": {}
}
}node9_approver_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all node9 approver channels and their current enabled/disabled state. It is categorised as a Read tool in the Node9-Proxy MCP Server, which means it retrieves data without modifying state.
Register the Node9-Proxy MCP server in PolicyLayer and add a rule for node9_approver_list: 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 Node9-Proxy. Nothing to install.
node9_approver_list 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 node9_approver_list 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 node9_approver_list. 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.
node9_approver_list is provided by the Node9-Proxy MCP server (node9-ai/node9-proxy). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
