## Why updown_list_rounds is rated Low

This tool retrieves and lists prediction market rounds with pagination and optional filtering. It performs no state changes, does not execute external operations, and does not move funds. The action is purely informational—querying existing round data from the UPDOWN prediction market protocol. This is a straightforward Read category tool with low severity risk.

From the tool's own definition: "Tool name 'updown_list_rounds' and description 'Paginated UPDOWN round list for a token, newest-first' indicate a retrieval/query operation with optional filtering parameters (tf and outcome filters)."

## Use case

AI agents call updown_list_rounds to retrieve information from Basis MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
