Search the Steam store for games and apps by name or keyword. Returns app IDs, names, icons, and price info. No API key required.
AI agents call steam_searchApps to retrieve information from Steam MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward search/query function that retrieves publicly available Steam store information. It has no capability to modify data, execute commands, delete resources, or affect player accounts. The blast radius of misuse is minimal—an agent could only retrieve information already publicly available on Steam's store. This clearly falls under the Read category with low severity.
From the tool's definition Tool description states it 'Search[es] the Steam store for games and apps' and 'Returns app IDs, names, icons, and price info.' These are retrieval operations with no side effects.
