List all n8n workflows with metadata
AI agents call workflow_list to retrieve information from N8n Fabric 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 workflow data without side effects. It performs a simple listing/enumeration operation, which is characteristic of a Read category tool. The metadata retrieved could inform subsequent actions, but the tool itself only provides information access.
From the tool's definition Tool name 'workflow_list' and description 'List all n8n workflows with metadata' indicate retrieval of workflow information with no modification or execution capability.
Attacks that exploit this kind of access
List all n8n workflows with metadata. It is categorised as a Read tool in the N8n Fabric MCP Server, which means it retrieves data without modifying state.
Register the N8n Fabric MCP server in PolicyLayer and add a rule for workflow_list: 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 Fabric. Nothing to install.
workflow_list 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 workflow_list 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 workflow_list. 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.
workflow_list is provided by the N8n Fabric MCP server (ry-ops/n8n-fabric). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
