AI agents call list to retrieve information from McFlow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays workflow information without creating, modifying, deleting, or executing any workflows. It is a pure read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'list' and description 'List all n8n workflows in this project' indicate a retrieval operation with no side effects. The parenthetical note '(use deployed to see workflows in n8n)' further confirms this is a query/listing action.
Attacks that exploit this kind of access
List all n8n workflows in this project (use deployed to see workflows in n8n). It is categorised as a Read tool in the McFlow MCP Server, which means it retrieves data without modifying state.
Register the McFlow MCP server in PolicyLayer and add a rule for 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 McFlow. Nothing to install.
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 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 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.
list is provided by the McFlow MCP server (mckinleymedia/mcflow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
