Notion has fully exposed its system-generated People Database to the developer ecosystem, introducing robust programmatic access across the Notion API, the native ntn CLI, and Custom Agents.

This update resolves a major bottleneck for HR teams and workspace administrators who previously could only manage this centralised directory through the manual user interface. The People Database acts as an automated registry tracking every identity in a workspace—including current members, deactivated legacy accounts, and external guests. By unlocking API endpoints for this system data, developers can now build seamless internal workflows that map real-time personnel changes directly to identity provider syncs, onboarding structures, and access auditing logs.

Crucially, this release marks the first time that workspace guests are available programmatically. While the standard List all users API endpoint traditionally restricted results to active, full members, the newly integrated system database allows automations to track, identify, and assign tasks to guests. While Model Context Protocol (MCP) support is currently excluded from this initial deployment, its rollout across other infrastructure guarantees that full multi-tool AI orchestration using your complete workspace directory is on the immediate horizon.
