AI agents use unpin_note to create or update resources in Kommo CRM MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kommo CRM MCP Server environment.
Unpinning a note is a reversible modification — it changes the pinned state of a note without deleting it. The note remains accessible, it just loses its pinned status. This is a Write operation with low severity since it's a minor, reversible UI/display change in the CRM.

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