List all workflows with complete data including nodes and connections. Warning: high token usage.
AI agents call list_workflows_full to retrieve information from n8n Workflow Builder MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing workflow data without any modification, deletion, or execution of operations. It performs a passive information-gathering function analogous to 'list' or 'get' operations. While high token usage suggests large response volumes, this does not change the fundamental Read category classification. No side effects or external operations are triggered.
From the tool's definition Tool name 'list_workflows_full' and description 'List all workflows with complete data' indicate a retrieval operation. The warning about 'high token usage' confirms data retrieval rather than modification or execution.
Documented attack patterns abuse exactly the kind of access list_workflows_full gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and n8n Workflow Builder MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_workflows_full:
{
"version": "1",
"default": "deny",
"tools": {
"list_workflows_full": {}
}
}list_workflows_full is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List all workflows with complete data including nodes and connections. Warning: high token usage. It is categorised as a Read tool in the n8n Workflow Builder MCP Server MCP Server, which means it retrieves data without modifying state.
Register the n8n Workflow Builder MCP Server MCP server in PolicyLayer and add a rule for list_workflows_full: 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 Workflow Builder MCP Server. Nothing to install.
list_workflows_full 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_workflows_full 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_workflows_full. 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_workflows_full is provided by the n8n Workflow Builder MCP Server MCP server (makafeli/n8n-workflow-builder). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from n8n Workflow Builder MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
