Get version history for a bill (introduced, engrossed, enrolled, etc.).
AI agents call get_bill_versions to retrieve information from Umbrella Terminal MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves version history for bills (introduced, engrossed, enrolled states), which is a read-only query operation. It has no side effects—it does not create, modify, delete, or execute anything. The context confirms this is part of a legislative intelligence querying system where all sibling tools (batch_get_entities, find_path, get_bill, etc.) are similarly read-only data retrieval operations.
From the tool's definition Tool name 'get_bill_versions' and description 'Get version history for a bill' indicate a retrieval operation querying legislative bill version data without any modification, deletion, or execution of external operations.
