Update note content by note id. This tool allows you to modify the content of an existing Kibela note. Before updating, it fetches the current content of the note to ensure proper version control. Note that you need the note ID (not the note path) to use this tool.
AI agents use kibela_update_note_content 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 modifies existing data (note content) in a reversible manner, which is the defining characteristic of the Write category. While updates can impact information that others rely on, the action is not destructive (data is not deleted), not financial, and does not execute arbitrary code.
From the tool's definition Tool description explicitly states: 'Update note content by note id' and 'allows you to modify the content of an existing Kibela note.' The 'update' action modifies data reversibly.
Documented attack patterns abuse exactly the kind of access kibela_update_note_content 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_update_note_content:
{
"version": "1",
"default": "deny",
"tools": {
"kibela_update_note_content": {
"limits": [
{
"counter": "kibela_update_note_content_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}kibela_update_note_content 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.

Update note content by note id. This tool allows you to modify the content of an existing Kibela note. Before updating, it fetches the current content of the note to ensure proper version control. Note that you need the note ID (not the note path) to use this tool. It is categorised as a Write tool in the MCP Kibela MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP Kibela MCP server in PolicyLayer and add a rule for kibela_update_note_content: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Kibela. Nothing to install.
kibela_update_note_content 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 kibela_update_note_content 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 kibela_update_note_content. 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.
kibela_update_note_content is provided by the MCP Kibela MCP server (kj455/mcp-kibela). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Kibela, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
