Show snapshot history for a document.
AI agents call refmd-list-snapshots to retrieve information from RefMD MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays snapshot history—a read-only operation with no side effects. It does not create, modify, delete, or execute any actions. While the server as a whole includes destructive tools (refmd-delete-document, refmd-delete-share) and write operations (refmd-create-document, refmd-edit-document), this specific tool is purely informational.
From the tool's definition Tool name 'refmd-list-snapshots' and description 'Show snapshot history for a document' indicate a retrieval operation that queries historical versions without modifying or deleting data.
