MOST DANGEROUS TOOLS

High Risk

The most dangerous Steam tools

Write · Low refresh_library This tool invalidates/clears a local cache, which is a reversible write operation (cache can be repopulated).

1 of Steam's 5 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Steam

PolicyLayer is an MCP gateway — it sits between your AI agents and Steam, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "refresh_library": {
    "limits": [
      {
        "counter": "refresh_library_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_game_details": {
    "limits": [
      {
        "counter": "get_game_details_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Steam — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on Steam? +
