AI agents use create_kibela_note to create or update resources in Kibela MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kibela MCP Server environment.
This tool creates new notes in a Kibela knowledge base, which modifies data reversibly. The action is Write-category (creates content) rather than Execute or Destructive, as it does not run arbitrary code, delete data, or cause financial effects. Severity is medium because unauthorized note creation could pollute a shared knowledge base but is reversible through deletion.

"default": "deny",
"tools": {
"create_kibela_note": {
"limits": [

"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
