## Why mlb_get_player_versus is rated Low

This tool queries and returns sports statistics and analytics without creating, modifying, deleting, or executing any operations. It presents no risk of unintended side effects, financial impact, or data destruction. Even if an AI agent misuses it by requesting data repeatedly, the worst outcome is retrieving statistics that are already publicly available, resulting in minimal security risk.

From the tool's own definition: "Tool retrieves 'head-to-head batting statistics' and 'matchup' data with no modification, deletion, or execution capabilities described. The verb 'Get' and action of fetching analytics data confirms a read-only query operation."

## Use case

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

## Recommended policy (PolicyLayer)
