Fireconnect is an open-source CLI orchestration tool developed by Fireworks AI (fw-ai) designed to route various AI coding agents and IDE extensions to Fireworks AI inference endpoints. Instead of running a resident daemon or proxy server, it directly manages and mutates the configuration files of supported coding tools on the local machine. In daily operations, developers interact with Fireconnect via the command line using straightforward commands to toggle model configurations. It enables switching third-party CLI agents and IDEs—such as Claude Code, OpenCode, Codex, Cursor, VS Code, and DeepSeek Harness—to run on Fireworks-hosted models. The orchestrator updates the native tool configurations in place and provides clean rollback mechanisms. A key differentiator for Fireconnect is its proxy-less design: running the `on` command updates the targeted tool's native configuration files, while running `off` restores the original configuration byte-for-byte. This removes the latency, maintenance overhead, and failure points associated with running local intermediary proxies or wrapper processes. Fireconnect is open-source software released under the Apache-2.0 license. It is distributed via a shell install script and npm/monorepo packages (`@packages/setup-cli`), offering a lightweight configuration bridge for teams standardizing on Fireworks AI endpoints.
In-place configuration rewrite — Direct modification of existing tool configurations without requiring background proxy processes or daemon services. - Byte-for-byte rollback — Restores original tool configuration files identically when turning Fireworks routing off. - Multi-agent compatibility — Provides support for routing CLI agents and IDE setups including Claude Code, OpenCode, Codex, Cursor, VS Code, and DeepSeek Harness. - Fireworks AI model integration — Points agent API requests toward models hosted on Fireworks AI infrastructure. - Zero wrapper execution — Allows developers to run their tools directly through native commands rather than wrapping calls in custom runner subshells.
Use cases
Use Case: Routing Terminal Coding Agents to Fireworks AI A developer using CLI agents like Claude Code or OpenCode wants to execute tasks against custom or cost-effective models hosted on Fireworks AI. By running the Fireconnect activation command, their local agent configuration is updated to route inference calls directly to Fireworks endpoints.
Use Case: Switching IDE Backend Configuration An engineer using Cursor or VS Code needs to benchmark coding performance on Fireworks-hosted models without manually editing JSON settings. Fireconnect automatically updates the editor's model configuration, allowing rapid testing across environments.
Use Case: Safe Reversible Configuration for Agent Harnesses A DevOps team needs to test experimental model configurations across DeepSeek Harness or Codex without breaking existing API setups. Fireconnect provides atomic state changes that can be restored byte-for-byte via the CLI once testing concludes.
Who it is for
Fireconnect is aimed at developers and engineering teams looking to route their terminal agents and IDE tools (like Cursor, Claude Code, and OpenCode) to Fireworks AI backend models without maintaining complex local proxy setups. It is not suitable for developers seeking a standalone coding agent with its own chat interface, as Fireconnect functions strictly as a configuration bridge for other tools.
Install guide
Installation Install Fireconnect using the provided shell installer or by building from the repository: bash curl -fsSL https://raw.githubusercontent.com/fw-ai/fireconnect/main/install.sh | bash Alternatively, install via the repository packages if using npm: bash git clone https://github.com/fw-ai/fireconnect.git cd fireconnect/packages/setup-cli npm install npm link
First Run Configure Fireconnect with your Fireworks AI credentials and select the target harness: bash # Ensure your Fireworks API key is exported export FIREWORKS_API_KEY="your-api-key-here" # Enable Fireworks routing for your installed tools fireconnect on
Example Session To activate Fireworks AI models for your agents and then revert configurations: bash # Route supported tools (e.g., Claude Code, Cursor) to Fireworks fireconnect on # Run your existing coding tools natively claude # Revert configuration files byte-for-byte to their original state fireconnect off
