AI agents call list_tasks 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 and displays a list of task templates organized by category (HTTP/API, Webhooks, Database, AI, Data Processing, Communication). It is purely informational—it queries metadata about available templates without creating, modifying, executing, or deleting anything. The blast radius of misuse is minimal; an AI agent could only retrieve information about template options, not perform actions with them.
From the tool's definition Tool name 'list_tasks' and description 'List task templates by category' indicate a retrieval/query operation with no modification or execution of actual workflows or data.
Attacks that exploit this kind of access
List task templates by category: HTTP/API, Webhooks, Database, AI, Data Processing, Communication. 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 list_tasks: 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.
list_tasks 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_tasks 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_tasks. 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_tasks 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.
