OpenRouter MCP Registry
A centralized model registry backed by OpenRouter. Prevents stale model names, standardizes model IDs, and exposes an MCP-compatible endpoint for AI clients.
About this UI: The browser pages (Models, Resolve, Sync Status) query the registry database directly. The Live Demo chatbot is a full MCP client — it connects to https://openrouter-registry-mcp.aroughidea.com/api/mcp at runtime, discovers tools dynamically, and routes every tool call through the MCP server. To connect your own AI client, see the MCP Integration page.
