AI agents call n8n_list_executions 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 only reads/queries execution history data from n8n. It has no side effects, does not modify any data, and simply returns a list of past workflow executions. Misuse risk is low as it only exposes metadata about workflow runs.
From the tool's definition 'List workflow executions' — retrieves execution records with pagination support (hasMore/nextCursor)
Attacks that exploit this kind of access
List workflow executions (returns up to limit). 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_executions: 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_executions 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_executions 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_executions. 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_executions 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.
