query-database
AI agents call query-database to retrieve information from Notion MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Query-database appears to retrieve or query data from Notion databases without side effects, fitting the Read category. The empty description is a limitation, but contextual sibling tools (search-notion, get-page, create-database-row, update-database-entry) suggest this tool follows the query/retrieve pattern.
From the tool's definition The tool name 'query-database' combined with the server description stating it provides 'searching, retrieving' capabilities indicates a read operation. However, the description for this specific tool is empty, which reduces confidence.

Yes. Add a rate_limit block to the query-database 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 query-database. 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.
query-database is provided by the Notion MCP Server MCP server (sahmadumass/notion-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
