list_ai_tools
List all 263 nodes marked with usableAsTool=true property. IMPORTANT: ANY node in n8n can be used as an AI tool - not just these! These nodes are optimized for AI usage but you can connect any node (Slack, Google Sheets, HTTP Request, etc.) to an AI Agent

What list_ai_tools does on Obsidian Elite RAG MCP Server
AI agents call list_ai_tools to retrieve information from Obsidian Elite RAG MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_ai_tools is rated Low
The tool retrieves and enumerates a list of available nodes/tools from an n8n workflow system. This is fundamentally a read operation—it queries existing configuration data and returns information. The description explicitly states it 'lists' nodes, which is a retrieval action with no side effects.
From the tool's definition Tool name is 'list_ai_tools' and description states it 'List[s] all 263 nodes marked with usableAsTool=true property.' This is a query/listing operation that retrieves metadata about available tools without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
The rule that runs list_ai_tools safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Obsidian Elite RAG MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_ai_tools, this is the rule to start with:
list_ai_tools is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Obsidian Elite RAG MCP Server, apply this rule, and every list_ai_tools call is checked against it from then on.
