AI agents call n8n_list_workflows 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 workflow metadata without side effects. It is purely informational (list, fetch pattern) with no capability to modify, execute, or delete workflows. The minimal metadata returned limits exposure. Severity is low because listing workflows reveals organizational structure but does not enable harmful actions without additional tools.
From the tool's definition Tool description explicitly states it 'List workflows (minimal metadata only)' with read-only outputs: 'id/name/active/dates/tags'. No mutation, deletion, or execution of workflows occurs—only retrieval of metadata.
Attacks that exploit this kind of access
List workflows (minimal metadata only). Returns id/name/active/dates/tags. Check hasMore/nextCursor for pagination. 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 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. 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 (mohsin-zaheer/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
