Retrieves a specific property of a Notion page. Use for properties with more than 25 references.
AI agents call notion_retrieve_page_property 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.
This tool performs a read-only operation that queries and returns data from a Notion page without making any modifications, executing code, or causing destructive changes. The blast radius of misuse is minimal—at worst, an agent could query properties it shouldn't have access to, but this is a data confidentiality issue rather than a system-level risk.
From the tool's definition Tool name contains 'retrieve' and description states 'Retrieves a specific property of a Notion page' with no mention of modification, deletion, or execution.
