Run open-source models inside Claude Desktop

Stop bouncing between browser tabs to test Llama or Mixtral. This Fireworks AI MCP Server lets Claude Desktop call the `chat` and `completion` tools to run lightning-fast inference on open weights models without leaving your conversation window. You get raw speed and direct access to the Fireworks API catalog inside your Claude Desktop interface. Claude Desktop handles the coordination, while the `list_models` tool ensures your agent always knows exactly which Fireworks AI models are currently available to boot up.

Generate images and transcribe audio in your chat

Feed audio files directly to Claude Desktop and let it run the `transcribe` tool to get clean text outputs from the Fireworks AI audio engine instantly. When you need visual assets, tell your Claude Desktop agent to trigger the `image` tool to spit out high-fidelity graphics right in your chat flow. This setup bypasses the standard Claude Desktop text-only constraints by tapping into the Fireworks AI multimodal API. By handling both voice-to-text and image generation under one roof, your local Claude Desktop agent processes complex multi-format inputs without requiring external script wrappers.

Build fast context maps with embeddings

Feed local documentation or codebases to Claude Desktop and let it run the `embed` tool. It generates precise vector embeddings via Fireworks AI to map out semantic relationships before processing large Claude Desktop prompts. This means your Claude Desktop agent can index massive text files locally using Fireworks AI embeddings, find the exact snippets you need, and feed them into the main chat context. It prevents context bloat and keeps your Fireworks AI token usage lean.
