AI agents call users_tags_list to retrieve information from Remnawave without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing user tags without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval function typical of Read category tools. The blast radius is minimal since listing tags poses no risk of data loss, financial impact, or unauthorized action execution.
From the tool's definition Tool name contains 'list' and description states 'List all user tags' — a retrieval operation with no modification or side effects.

Documented attack patterns abuse exactly the kind of access users_tags_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Remnawave, and nothing reaches the server without passing your rules. This is the rule we recommend for users_tags_list:
{
"version": "1",
"default": "deny",
"tools": {
"users_tags_list": {}
}
}users_tags_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all user tags. It is categorised as a Read tool in the Remnawave MCP Server, which means it retrieves data without modifying state.
Register the Remnawave MCP server in PolicyLayer and add a rule for users_tags_list: 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 Remnawave. Nothing to install.
users_tags_list 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 users_tags_list 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 users_tags_list. 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.
users_tags_list is provided by the Remnawave MCP server (trackline/mcp-remnawave). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
