AI agents call list_tags to retrieve information from Roadmap Skill without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata (tags) from a project without altering state, creating resources, or triggering external operations. It is a straightforward query operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name is 'list_tags' and description states 'List all tags in a project' — a retrieval operation with no modification or side effects.
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 Roadmap Skill, 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.
Free to start. No card required.
List all tags in a project. It is categorised as a Read tool in the Roadmap Skill MCP Server, which means it retrieves data without modifying state.
Register the Roadmap Skill 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 Roadmap Skill. 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 Roadmap Skill MCP server (shiquda/roadmap-skill). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
