AI agents call find-nodes-by-type 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 tool searches or filters existing nodes by type, which is a read-only query operation. No description was provided, but the name and context from sibling read tools (get-nodes, get-node-info) strongly indicate this retrieves data without side effects. Confidence is slightly lowered due to the empty description, but the naming pattern is clear.
From the tool's definition Tool name 'find-nodes-by-type' suggests querying/searching for nodes by their type; combined with sibling tools like 'get-nodes', 'get-node-info', and 'get-flows' which are clearly read-only retrieval operations, this tool appears to follow the same pattern…
Attacks that exploit this kind of access
find-nodes-by-type. 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 find-nodes-by-type: 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.
find-nodes-by-type 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 find-nodes-by-type 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 find-nodes-by-type. 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.
find-nodes-by-type 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.
