A lightweight proxy that allows Claude Code to use the Fireworks.ai API without the 5K token streaming limitation.
It translates Anthropic-style requests into Fireworks-compatible requests, supporting both streaming and non-streaming modes and tool calls.

• Local proxy between Claude Code and Fireworks.ai
• Automatic streaming for all requests (>5K token support)
• Tool call support
• Logging of requests and responses in /logs
• Easy model switching with included selector script
• Written in TypeScript, runnable via tsx or npm global bin

• Node.js 18+
• Fireworks.ai API key
• Claude Code (or Anthropic-compatible client)

You can install globally from npm:

npm install -g claude-code-fireworks.ai

ccf init

This will create ~/.claude-code-fireworks

mv ~/.claude-code-fireworks/.env.example ~/.claude-code-fireworks/.env

Update .env with your Fireworks API key and choose model FIREWORKS_API_KEY=fw_... FIREWORKS_MODEL=accounts/fireworks/models/kimi-k2-instruct

Start the proxy server and Claude Code

ccf start

To change model directly:

ccf model
