AI agents call get_node to retrieve information from n8n-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries n8n node documentation and metadata with multiple detail levels and informational modes. It has no write, delete, or execute capabilities—purely informational access. The progressive detail levels and search modes are all passive lookups.
From the tool's definition Tool name 'get_node' and description indicate retrieval operations only: 'Get node info', 'docs (markdown documentation)', 'find properties', 'version info'. All modes are read-only queries with no modification, deletion, or execution capabilities.

Get node info with progressive detail levels and multiple modes. Detail: minimal (~200 tokens), standard (~1-2K, default), full (~3-8K). Modes: info (default), docs (markdown documentation), search_properties (find properties), versions/compare/breaking/migrations (version info). Use format=. It is categorised as a Read tool in the n8n-MCP MCP Server, which means it retrieves data without modifying state.
Register the n8n- MCP server in PolicyLayer and add a rule for get_node: 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. Nothing to install.
get_node 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 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. 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 is provided by the n8n- MCP server (tako3832/n8n-mcp-main). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
