Finalyy ⚡ — Free AI Models via MCP

No API keys. No subscriptions. Just point your IDE and go.

Finalyy converts free browser-based AI trials (ChatGPT, Claude, Gemini, DeepSeek, Flux, Kling, and more) into MCP tools and OpenAI-compatible endpoints. One CLI command, zero cost, production-grade quality.

npx finalyy init     # One-time setup
npx finalyy start    # Launch MCP server on localhost:1337

Then connect any MCP client — Cursor, Claude Desktop, Codex, Continue.dev, Cline, OpenClaw — and use frontier models for free.

Why Finalyy

Every week, new AI providers launch free browser trials of frontier models. Developers can use them in a browser but cannot integrate them into their tools, IDEs, or agents because:

  • Providers charge for API keys ($50–$500/mo)

  • Browser sessions don't expose OpenAI-compatible endpoints

  • No standard way to convert web trials → MCP tools

  • Each provider has a different authentication mechanism

Finalyy solves this — one unified MCP server, community-driven provider registry, auto-fallback, zero API keys.
