Query notes by properties like type, tags, confidence, verified status, and dates. Use this for filtering without full-text search. Supports cross-vault queries.
AI agents call palace_query 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_query is a read-only tool that retrieves and filters information from the Obsidian vault based on metadata properties (type, tags, confidence, verified status, dates). It has no side effects—it does not create, modify, delete, or execute any operations. Even though it supports cross-vault queries, the scope remains informational retrieval.
From the tool's definition Tool description states 'Query notes by properties' and 'filtering without full-text search' with no mention of modifying, deleting, or executing operations. The verb 'query' combined with filtering functionality indicates data retrieval only.
Attacks that exploit this kind of access
Query notes by properties like type, tags, confidence, verified status, and dates. Use this for filtering without full-text search. Supports cross-vault queries. 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_query: 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_query 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_query 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_query. 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_query 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.
