Get a list of all tags in Anybox with their IDs, names, colors, and bookmark counts.
AI agents call list_tags to retrieve information from Anybox MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves organizational metadata from the Anybox bookmark manager. It performs no side effects, creates no data, executes no code, and cannot delete or modify anything. It is a straightforward Read operation with minimal risk. The low severity reflects that leaking tag metadata poses negligible security concern.
From the tool's definition Tool name is 'list_tags' and description states it 'Get a list of all tags' — a retrieval operation with no modification capability. The description explicitly indicates read-only enumeration of existing metadata (IDs, names, colors, bookmark counts).
Documented attack patterns abuse exactly the kind of access list_tags gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Anybox MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_tags:
{
"version": "1",
"default": "deny",
"tools": {
"list_tags": {}
}
}list_tags is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a list of all tags in Anybox with their IDs, names, colors, and bookmark counts. It is categorised as a Read tool in the Anybox MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Anybox MCP Server MCP server in PolicyLayer and add a rule for 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 Anybox MCP Server. Nothing to install.
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 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 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.
list_tags is provided by the Anybox MCP Server MCP server (tommertron/anyboxmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Anybox MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
