Lutris MCP Server
Enables AI assistants to browse, search, and manage a Lutris Linux gaming library. It provides tools for modifying game details, organizing categories, and accessing collection statistics directly from the Lutris SQLite database.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
25/25 tools missing one or more hints — bulk_assign_category (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); bulk_update_games (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_categories (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +22 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Descriptions match behaviour
2 tools describe read intent but their handlers mutate — check_game_running (line 48: execSync(`pgrep -af "${pattern}"`, {); list_runners (line 19: execSync('pgrep -af "lutris"', {)
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
22/25 tool handlers declare input schemas (88%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests pass
npm test failed — tests do not pass
Make sure npm test runs cleanly. Common cause: missing build step or missing env vars.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Tool description accuracy
check_game_running: description implies read-only but handler writes/deletes/executes; list_runners: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
