clash_player_war_history

This tool appears to fetch a player's war history from the Clash of Clans API, which is a read-only operation that retrieves historical game data for analysis purposes. No modification, execution, deletion, or financial impact is possible. The empty description lowers confidence slightly, but the clear read-only intent from server context and naming pattern justifies the Read category with high confidence.
From the tool's definition Tool name 'clash_player_war_history' combined with sibling tools that all use 'clash_get_' prefix and 'clash_api_get' suggest this retrieves historical data. The server description confirms it reads 'official API data' for analysis.
