List available project playbooks and their descriptions
AI agents call list_playbooks to retrieve information from Obsidian Ai Curator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about existing playbooks without creating, modifying, deleting, or executing anything. It is a straightforward read operation with minimal risk, as it only exposes metadata about available playbooks rather than sensitive data or capabilities for external systems.
From the tool's definition 'List available project playbooks and their descriptions' - the verb 'list' indicates retrieval of existing data with no modification or execution.
Documented attack patterns abuse exactly the kind of access list_playbooks gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Obsidian Ai Curator, and nothing reaches the server without passing your rules. This is the rule we recommend for list_playbooks:
{
"version": "1",
"default": "deny",
"tools": {
"list_playbooks": {}
}
}list_playbooks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
