AI agents call search_apps to retrieve information from Steam without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the Steam store database and returns search results. It retrieves publicly available information about games (names, IDs, prices, ratings) without any side effects, data modifications, or external operations. It is a standard read-only query operation consistent with other tools on this server like get_game_details and get_game_news.
From the tool's definition Tool is described as 'Search the Steam store by game name' with outputs of 'matching apps with App IDs, prices, and Metascores' — purely informational retrieval with no modification, creation, or deletion of data.
Attacks that exploit this kind of access
Search the Steam store by game name. Returns matching apps with App IDs, prices, and Metascores. It is categorised as a Read tool in the Steam MCP Server, which means it retrieves data without modifying state.
Register the Steam MCP server in PolicyLayer and add a rule for search_apps: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Steam. Nothing to install.
search_apps is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_apps rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for search_apps. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
search_apps is provided by the Steam MCP server (matheusslg/steam-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
