Retrieve all available tags for workflow organization. Returns tag ID and name. Use this before assigning tags to workflows or to see your tagging structure.
AI agents call n8n_list_tags to retrieve information from n8n Management MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple data retrieval operation that queries existing tags without creating, modifying, deleting, or executing any actions. It has negligible security risk as it only exposes metadata about tag definitions already stored in the n8n instance.
From the tool's definition Tool description explicitly states 'Retrieve all available tags' and 'Returns tag ID and name'. The verb 'Retrieve' and the clarification to 'Use this before assigning tags' indicate a query-only operation with no modification or side effects.

Retrieve all available tags for workflow organization. Returns tag ID and name. Use this before assigning tags to workflows or to see your tagging structure. It is categorised as a Read tool in the n8n Management MCP Server MCP Server, which means it retrieves data without modifying state.
Register the n8n Management MCP Server MCP server in PolicyLayer and add a rule for n8n_list_tags: 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 Management MCP Server. Nothing to install.
n8n_list_tags 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_tags 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_tags. 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_tags is provided by the n8n Management MCP Server MCP server (node2flow-th/n8n-management-mcp-community). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
