list_bills
AI agents call list_bills to retrieve information from Taiwan Legislative Yuan MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool lists bills from the Legislative Yuan database, which is a read-only query operation with no side effects. It retrieves data but does not create, modify, delete, or execute any operations. Even with an empty description, the name and context indicate this is a retrieval function.
From the tool's definition Tool name 'list_bills' combined with server description indicating 'comprehensive access to Taiwan's Legislative Yuan data including bills'. The verb 'list' is characteristic of retrieval operations that return collections without modification.
