OpenRouter MCP Integration

AVELIN API is compatible with OpenRouter MCP — All-in-one MCP server that gives Claude Desktop, Cursor, Kiro, VS Code, Windsurf, and Cline access to OpenRouter's 300+ LLMs — chat, image/audio/video analysis, and generation.

OpenRouter MCP is the all-in-one MCP (Model Context Protocol) server that unlocks 300+ AI models inside your favorite development tools. Its killer feature is universal MCP access: give Claude Desktop, Cursor, VS Code, Windsurf, and Cline the ability to chat, analyze images/audio/video, AND generate media — including video generation with Veo, Sora, and Seedance — all through a single MCP server. One server, every model, every modality.

Built for developers who want maximum model flexibility inside their IDE or editor without juggling multiple integrations. OpenRouter MCP turns any MCP-compatible tool into a gateway to the entire AI model ecosystem. Point it at AVELIN for governed, high-performance access to frontier models.
