add_game · Lutris MCP Server MCP: Risk & Policy

WHAT IT DOES

What add_game does on Lutris MCP Server

AI agents use add_game to create or update resources in Lutris MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Lutris MCP Server environment.

WHY IT NEEDS A POLICY

Why add_game needs a policy

This tool creates new data (game entries) in the Lutris database, which is a Write operation. It is not Destructive because adding a game is reversible (the entry can be removed). It is not Execute because it does not run code or trigger external operations—it simply creates a structured record.

From the tool's definition 'Add a new game to the Lutris library' creates a new record in the Lutris SQLite database; this is a reversible creation operation that modifies the library state.

Verdict

add_game Rate-limited

add_game stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
