List version history of a document
AI agents call docs_list_versions to retrieve information from Docs 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 queries version history information about a document. It performs a read-only operation with no side effects—it neither modifies, deletes, nor executes code. The action is a simple retrieval of existing version records, making it a Read category tool with low severity risk.
From the tool's definition Tool name 'docs_list_versions' and description 'List version history of a document' indicate retrieval of historical metadata without modification or deletion.
