List all topics covered in the ASTGL knowledge base. Shows article titles, descriptions, URLs, and section headings.
AI agents call list_topics to retrieve information from ASTGL Knowledge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries information from a knowledge base without creating, modifying, deleting, or executing anything. It is a straightforward read operation that returns metadata about articles. No data is altered, no code is executed, and no external operations are triggered. The low severity reflects that misuse would only involve accessing already-public knowledge base content.
From the tool's definition Tool name is 'list_topics' and description states it 'List all topics' and 'Shows article titles, descriptions, URLs, and section headings.' These are retrieval operations with no modification or side effects.
Documented attack patterns abuse exactly the kind of access list_topics gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ASTGL Knowledge, and nothing reaches the server without passing your rules. This is the rule we recommend for list_topics:
{
"version": "1",
"default": "deny",
"tools": {
"list_topics": {}
}
}list_topics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all topics covered in the ASTGL knowledge base. Shows article titles, descriptions, URLs, and section headings. It is categorised as a Read tool in the ASTGL Knowledge MCP Server, which means it retrieves data without modifying state.
Register the ASTGL Knowledge MCP server in PolicyLayer and add a rule for list_topics: 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 ASTGL Knowledge. Nothing to install.
list_topics 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_topics 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_topics. 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_topics is provided by the ASTGL Knowledge MCP server (mcp-astgl-knowledge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ASTGL Knowledge, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
