List known topic hubs extracted from the corpus.
AI agents call list_topics to retrieve information from The Agent Times without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
limit | integer | — | Number of topics to return (max 50) |
Parameters from the server's own tool schema.
Even though list_topics only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
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 The Agent Times, 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 known topic hubs extracted from the corpus. It is categorised as a Read tool in the The Agent Times MCP Server, which means it retrieves data without modifying state.
list_topics accepts 1 parameter: limit. The full parameter table on this page comes from the server's own tool schema.
Register the The Agent Times 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 The Agent Times. 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 The Agent Times MCP server (theagenttimes/news). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
