AI agents use kibela_create_note to create or update resources in MCP Kibela — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Kibela environment.
This tool creates new data (notes) in Kibela, which is reversible (notes can be deleted or modified later). It does not execute arbitrary code, delete data irreversibly, or handle financial transactions.
From the tool's definition Tool description states 'Create a new note in Kibela', which is a create operation that adds new data to the system. The name 'kibela_create_note' confirms this is a write action.
Documented attack patterns abuse exactly the kind of access kibela_create_note gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Kibela, and nothing reaches the server without passing your rules. This is the rule we recommend for kibela_create_note:
{
"version": "1",
"default": "deny",
"tools": {
"kibela_create_note": {
"limits": [
{
"counter": "kibela_create_note_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}kibela_create_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.
