Query a database
AI agents call notion_query_database to retrieve information from MCP Notion Server (@suncreation) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a database query operation, which is a fundamental read operation. It retrieves information from a Notion database without creating, modifying, or deleting any data. The blast radius of misuse is minimal—worst case an agent could query sensitive information it shouldn't access, but cannot alter workspace state or cause irreversible changes. This aligns clearly with the Read category.
From the tool's definition Tool name 'notion_query_database' and description 'Query a database' indicate a read-only operation that retrieves data from a Notion database without modifying it.

Query a database. It is categorised as a Read tool in the MCP Notion Server (@suncreation) MCP Server, which means it retrieves data without modifying state.
Register the MCP Notion Server (@suncreation) 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 MCP Notion Server (@suncreation). 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 MCP Notion Server (@suncreation) MCP server (suncreation/mcp-notion-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
