List all annotation tags available in the n8n instance. Args: - limit (number): Max results (1-250, default 20) - cursor (string?): Pagination cursor
AI agents call n8n_list_tags to retrieve information from n8n 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 read-only operation that lists existing tags with pagination support. It has no side effects, does not modify any state, and returns metadata about the n8n instance. The blast radius of misuse is minimal—an agent could enumerate tags but cannot create, modify, or delete them, nor can it execute workflows or access sensitive data beyond tag names.
From the tool's definition Tool name 'n8n_list_tags' and description 'List all annotation tags available in the n8n instance' indicate a query operation that retrieves data without modification.
Attacks that exploit this kind of access
List all annotation tags available in the n8n instance. Args: - limit (number): Max results (1-250, default 20) - cursor (string?): Pagination cursor. It is categorised as a Read tool in the n8n MCP Server MCP Server, which means it retrieves data without modifying state.
Register the n8n 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 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 MCP Server MCP server (verzth/mcp-n8n). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
