list_bills
AI agents call list_bills 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 or queries legislative bill information without side effects. The 'list_' prefix strongly suggests data enumeration/retrieval. No modification, deletion, code execution, or financial transactions are implied. Even if misused by an AI agent, the blast radius is limited to information disclosure of publicly available legislative data.
From the tool's definition Tool name 'list_bills' indicates retrieval of bill data with no modification capability. Sibling tools like 'get_bill', 'get_bill_amendments', 'get_bill_funding' are all read-only query operations on legislative data.
