Get the palace directory tree structure with domain pattern analysis. Essential for understanding vault organization before storing knowledge.
AI agents call palace_structure to retrieve information from Obsidian Palace MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
palace_structure reads and returns directory information and organizational patterns. It has no side effects, creates no new data, executes no code, and cannot delete or modify existing content. This is a straightforward information retrieval operation, placing it firmly in the Read category with low severity since understanding vault structure poses minimal risk even if an AI agent misuses it.
From the tool's definition Tool description explicitly states 'Get the palace directory tree structure' with 'domain pattern analysis' - these are retrieval operations that query vault organization without modifying data.
Attacks that exploit this kind of access
Get the palace directory tree structure with domain pattern analysis. Essential for understanding vault organization before storing knowledge. It is categorised as a Read tool in the Obsidian Palace MCP MCP Server, which means it retrieves data without modifying state.
Register the Obsidian Palace MCP server in PolicyLayer and add a rule for palace_structure: 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 Obsidian Palace MCP. Nothing to install.
palace_structure is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the palace_structure 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 palace_structure. 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.
palace_structure is provided by the Obsidian Palace MCP server (probably-computers/obsidian-palace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
