AI agents call get_node_info to retrieve information from n8n MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about workflow node types—their properties, configurations, and capabilities. It is a read-only operation that queries information without creating, modifying, deleting, or executing anything. No data is changed and no external operations are triggered. It matches the 'Read' category pattern of fetch/get operations.
From the tool's definition Tool name 'get_node_info' and description 'Возвращает подробную информацию об узле по его типу' (Returns detailed information about a node by its type) indicate a query/retrieval operation without side effects.
Attacks that exploit this kind of access
Возвращает подробную информацию об узле по его типу. It is categorised as a Read tool in the n8n MCP Server MCP Server, which means it retrieves data without modifying state.
Register the n8n MCP Server 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 n8n MCP Server. 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 n8n MCP Server MCP server (ospray-creator/n8n-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_node_info is one line of n8n MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
