Disable a node9 shield. Use node9_shield_list to see currently active shields.
AI agents use node9_shield_disable to create or update resources in Node9-Proxy — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Node9-Proxy environment.
An AI agent can call node9_shield_disable faster than any human can review — one bad instruction and it creates or modifies resources in Node9-Proxy by the hundred, each call as confident as the last.
Documented attack patterns abuse exactly the kind of access node9_shield_disable 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_shield_disable:
{
"version": "1",
"default": "deny",
"tools": {
"node9_shield_disable": {
"limits": [
{
"counter": "node9_shield_disable_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}node9_shield_disable stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Disable a node9 shield. Use node9_shield_list to see currently active shields. It is categorised as a Write tool in the Node9-Proxy MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Node9-Proxy MCP server in PolicyLayer and add a rule for node9_shield_disable: 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_shield_disable is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the node9_shield_disable 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_shield_disable. 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_shield_disable 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.
