AI agents call get_topics to retrieve information from Telegram MCP Complete without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing topics from a group without modifying, deleting, or executing operations. It is a pure read operation that queries and returns information about existing group topics.
From the tool's definition Tool name 'get_topics' and description '获取群组中的所有话题' (Get all topics in a group) indicate data retrieval with no side effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and Telegram MCP Complete, and nothing reaches the server without passing your rules. This is the rule we recommend for get_topics:
{
"version": "1",
"default": "deny",
"tools": {
"get_topics": {}
}
}get_topics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
