AI agents call list_node_templates 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 or lists existing workflow templates from a database of 399 community workflows. It performs a read-only search operation with no side effects, data modification, code execution, or destructive capability. The low severity reflects minimal blast radius—misuse would only expose template information already public in the community repository.
From the tool's definition Tool name 'list_node_templates' with description 'Find templates using specific nodes' indicates a query/retrieval operation.
Attacks that exploit this kind of access
Find templates using specific nodes. 399 community workflows. Use FULL types:. 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 list_node_templates: 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.
list_node_templates 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 list_node_templates 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 list_node_templates. 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.
list_node_templates is provided by the n8n- MCP server (mohsin-zaheer/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
