AI agents call get-flows-formatted 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 appears to retrieve or query existing flow data from Node-RED without modifying, deleting, or executing operations. The 'get-' prefix and absence of description suggesting mutations or side effects classify this as Read. Severity is low as retrieval operations have minimal blast radius. Confidence is moderately high based on naming convention, though the empty description reduces certainty slightly.
From the tool's definition Tool name 'get-flows-formatted' indicates retrieval of flow information in a formatted representation. No description provided, but naming pattern and context among sibling tools (get-flows, get-flow, get-nodes) suggest a read-only query operation.
Attacks that exploit this kind of access
get-flows-formatted. 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-flows-formatted: 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-flows-formatted 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-flows-formatted 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-flows-formatted. 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-flows-formatted 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.
