AI agents call list_accounts 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 queries and retrieves account metadata without creating, modifying, or deleting data. It has no side effects beyond information disclosure. While account information could be sensitive in a multi-account Telegram context, the read-only nature and internal visibility scope (listing existing accounts already under the agent's control) makes this a standard Read operation with low blast radius if misused.
From the tool's definition Tool name 'list_accounts' and description indicating it 'retrieves...list and status information' (usernames, user IDs, online status, usage counts) with no modification or deletion capability.

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 list_accounts:
{
"version": "1",
"default": "deny",
"tools": {
"list_accounts": {}
}
}list_accounts 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 list_accounts 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_accounts. 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_accounts is provided by the Telegram MCP Complete MCP server (you922/telegram-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
