AI agents use create_topic to create or update resources in Telegram MCP Complete — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Telegram MCP Complete environment.
This tool creates a new topic/thread within a Telegram supergroup, which is a write operation that modifies group structure. While reversible (topics can be deleted), it affects group organization and could be misused to spam or disrupt group management. Severity is medium because the impact is localized to group metadata rather than destructive or having financial consequences.
From the tool's definition Tool description translates to 'Create a topic in a group (only supports supergroups)'. The verb 'create' indicates data creation in a Telegram supergroup, a reversible operation.
Documented attack patterns abuse exactly the kind of access create_topic gives an agent:
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 create_topic:
{
"version": "1",
"default": "deny",
"tools": {
"create_topic": {
"limits": [
{
"counter": "create_topic_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_topic stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

create_topic is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_topic 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 create_topic. 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.
create_topic 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.
Start from Telegram MCP Complete, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
