List workflows from the n8n instance with optional filtering. Args: - active (boolean?): Filter by active/inactive status - name (string?): Filter by workflow name (partial match) - tags (string?): Comma-separated tag names to filter by - projectId (string?): Filter by project ID - limit (number)...
AI agents call n8n_list_workflows to retrieve information from n8n MCP Server 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 with optional filters and pagination. It has no side effects—it does not create, modify, delete, or execute workflows. The filtering parameters are read-only operations. This is a straightforward data retrieval use case, making it a Read category tool with low severity risk.
From the tool's definition Tool name 'n8n_list_workflows' and description 'List workflows from the n8n instance with optional filtering' indicate a retrieval operation.
Attacks that exploit this kind of access
List workflows from the n8n instance with optional filtering. Args: - active (boolean?): Filter by active/inactive status - name (string?): Filter by workflow name (partial match) - tags (string?): Comma-separated tag names to filter by - projectId (string?): Filter by project ID - limit (number): Max results per page (1-250, default 20) - cursor (string?): Pagination cursor from previous response - response_format (. It is categorised as a Read tool in the n8n MCP Server MCP Server, which means it retrieves data without modifying state.
Register the n8n MCP Server MCP server in PolicyLayer and add a rule for n8n_list_workflows: 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 Server. Nothing to install.
n8n_list_workflows 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 n8n_list_workflows 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 n8n_list_workflows. 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.
n8n_list_workflows is provided by the n8n MCP Server MCP server (verzth/mcp-n8n). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
