AI agents call api-help to retrieve information from Node Red without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'api-help' strongly suggests a utility for retrieving API documentation or usage information. Such tools are typically read-only and informational. However, confidence is moderate (0.6) because the empty description prevents definitive verification of the tool's actual behavior. If it merely returns help text or documentation, it belongs in Read with low severity.
From the tool's definition Tool named 'api-help' with empty description; conventionally, help/documentation tools retrieve information without side effects.
Attacks that exploit this kind of access
api-help. It is categorised as a Read tool in the Node Red MCP Server, which means it retrieves data without modifying state.
Register the Node Red MCP server in PolicyLayer and add a rule for api-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 Node Red. Nothing to install.
api-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 api-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 api-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.
api-help is provided by the Node Red MCP server (node-red-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
