Query a database in Notion
AI agents call notion_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.
The term 'query' combined with 'database' in a read context implies data retrieval. No language suggests creation, modification, or deletion of data. The sibling tools include destructive operations (notion_delete_block), write operations (notion_create_database, notion_append_block_children), and other reads (notion_retrieve_*), confirming this tool's position as a retrieval operation.
From the tool's definition Tool name 'notion_query_database' and description 'Query a database in Notion' indicate a read-only operation that retrieves data from a Notion database without modifying it.
Attacks that exploit this kind of access
Query a database in Notion. It is categorised as a Read tool in the Notion MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Notion MCP Server MCP server in PolicyLayer and add a rule for notion_query_database: 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 Notion MCP Server. Nothing to install.
notion_query_database 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 notion_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 notion_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.
notion_query_database is provided by the Notion MCP Server MCP server (kimjungyeol/mcp-notion-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
