get entitites which have unread messages in it
AI agents call get_unread_entities to retrieve information from Telegram MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries state to retrieve information about entities with unread messages. It performs no writes, deletions, code execution, or financial operations. While it could expose user conversation metadata, it is fundamentally a read-only query operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name contains 'get' and description states 'get entities which have unread messages' — this is a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_unread_entities gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Telegram MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_unread_entities:
{
"version": "1",
"default": "deny",
"tools": {
"get_unread_entities": {}
}
}get_unread_entities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Yes. Add a rate_limit block to the get_unread_entities 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 get_unread_entities. 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.
get_unread_entities is provided by the Telegram MCP Server MCP server (prem-research/telegram-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Telegram MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
