THE RISK

Low Risk

Why get_execution needs a policy

This tool retrieves and queries execution data without modifying, creating, or deleting any resources. It is a straightforward data retrieval operation with minimal blast radius if misused by an AI agent—the worst outcome would be information disclosure of execution logs or metadata that the agent is already authorized to access.

From the tool's definition Tool name 'get_execution' and description 'Retrieve detailed information about a specific workflow execution' indicate a read-only query operation with no side effects.

POLICY

How to control get_execution

PolicyLayer is an MCP gateway — it sits between your AI agents and n8n MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_execution:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_execution": {}
  }
}

get_execution is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register n8n MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about get_execution

What does the get_execution tool do? +

Retrieve detailed information about a specific workflow execution. It is categorised as a Read tool in the n8n MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_execution? +

Register the n8n MCP Server MCP server in PolicyLayer and add a rule for get_execution: 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.

What risk level is get_execution? +

get_execution is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_execution? +

Yes. Add a rate_limit block to the get_execution 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.

How do I block get_execution completely? +

Set action: deny in the PolicyLayer policy for get_execution. 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.

What MCP server provides get_execution? +

get_execution is provided by the n8n MCP Server MCP server (leonardsellem/n8n-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every n8n MCP Server tool call.

Start from n8n MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
