Retrieve detailed information about a specific archival record.
AI agents call na_get_record to retrieve information from Nationaal Archief MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves archival records from the Netherlands National Archive collection. It performs a data lookup operation with no capability to modify, delete, or execute external code. The primary function is informational access to historical documents and records. Even if misused by an AI agent, retrieval of archival metadata poses minimal risk since these are typically public or semi-public historical records.
From the tool's definition Tool name contains 'get' and description states 'Retrieve detailed information about a specific archival record' — these are characteristic Read operations that query and return data without modification or side effects.
