Get full schema/details for a specific node type.
AI agents call get_node_type to retrieve information from N8n Workflow Tester Safe without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a catalog to retrieve information about a node type definition. It does not create, modify, delete, or execute anything—it simply reads and returns schema metadata. Within the context of a workflow testing server focused on inspection and analysis, this is a safe read operation with minimal blast radius if misused.
From the tool's definition Tool retrieves schema/details for a node type with no indication of modification or execution. The verb 'Get' and the description 'Get full schema/details' indicate a retrieval operation with no side effects.

Get full schema/details for a specific node type. It is categorised as a Read tool in the N8n Workflow Tester Safe MCP Server, which means it retrieves data without modifying state.
Register the N8n Workflow Tester Safe MCP server in PolicyLayer and add a rule for get_node_type: 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 Workflow Tester Safe. Nothing to install.
get_node_type 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_type 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_type. 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_type is provided by the N8n Workflow Tester Safe MCP server (souzix76/n8n-workflow-tester-safe). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
