AI agents call get-node-info 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 'get-' prefix is characteristic of read operations. While the description is empty (reducing confidence slightly), the tool name and context of sibling read tools (get-flows, get-diagnostics) strongly suggest this retrieves node information without side effects. No evidence of data modification, deletion, or execution of arbitrary code.
From the tool's definition Tool name 'get-node-info' indicates information retrieval. The description is empty, but based on naming convention and sibling tools (get-diagnostics, get-flows, get-nodes), this appears to be a getter/query operation that retrieves metadata about a Node-RED…
Attacks that exploit this kind of access
get-node-info. 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 get-node-info: 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.
get-node-info 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-node-info 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-node-info. 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-node-info 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.
