About OpenCritic MCP Server
Equip your AI agent with the most reliable video game intelligence available via OpenCritic. This unified server provides your agent with instant access to aggregate review scores, detailed critic snippets, and historical rankings for thousands of games. Your agent can instantly search for specific titles, audit recent review trends, and retrieve the Hall of Fame for any given year without you ever needing to browse a review site. Whether you are identifying the best games of the year or auditing individual critic opinions, your agent acts as a dedicated gaming analyst through natural conversation.
Mastra's agent abstraction provides a clean separation between LLM logic and OpenCritic tool infrastructure. Connect 8 tools through the Vinkius and use Mastra's built-in workflow engine to chain tool calls with conditional logic, retries, and parallel execution — deployable to any Node.js host in one command.
