AI agents use create_meeting_note to create or update resources in Obsidian MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Obsidian MCP Server environment.
This tool creates new structured notes in the Obsidian vault with meeting-related content. Creation of notes is a reversible operation (notes can be edited or deleted), placing it firmly in the Write category rather than Read (it modifies data) or Destructive (modifications are reversible). The blast radius is low—misuse would generate unwanted meeting notes, which are easily remediated.
From the tool's definition Tool name 'create_meeting_note' and description 'Meeting notes with agenda/action items' indicate creation of new note content. The verb 'create' and context of generating structured meeting documentation (agenda, action items) is a Write operation.
Documented attack patterns abuse exactly the kind of access create_meeting_note gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Obsidian MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_meeting_note:
{
"version": "1",
"default": "deny",
"tools": {
"create_meeting_note": {
"limits": [
{
"counter": "create_meeting_note_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_meeting_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.

create_meeting_note 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 create_meeting_note 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 create_meeting_note. 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.
create_meeting_note is provided by the Obsidian MCP Server MCP server (kynlos/obsidian-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
