AI agents call get_template 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 template data by identifier and allows the caller to select the detail level of the response. It performs a query operation with no side effects—no data is created, modified, deleted, or executed. The tool is purely informational, making it a Read category risk.
From the tool's definition Tool description states 'Get template by ID' with modes that control 'response size' (nodes_only, structure, full), indicating data retrieval only. No modification, deletion, execution, or financial operations are described.
Attacks that exploit this kind of access
Get template by ID. Use mode to control response size: nodes_only (minimal), structure (nodes+connections), full (complete workflow). 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_template: 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_template 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_template 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_template. 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_template is provided by the n8n- MCP server (spring1237/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
