This tool modifies the notification/mute state of a conversation, which is a reversible write action. It does not delete data, execute code, or involve financial transactions. The blast radius is low since muting/unmuting a conversation has minimal impact and is easily reversible.

Documented attack patterns abuse exactly the kind of access mute_conversation gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Instagram DM MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for mute_conversation:
{
"version": "1",
"default": "deny",
"tools": {
"mute_conversation": {
"limits": [
{
"counter": "mute_conversation_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}mute_conversation 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.
