Overview

Route Claude Code, OpenCode, Codex, Pi, Cursor, VS Code, and Deep Agents through Fireworks AI or Microsoft Foundry models

FireConnect is an open-source CLI that routes agentic coding harnesses through Fireworks models. Install once, sign in once, then flip any supported harness on or off without hand-editing config files.

Choose where inference runs:

• Direct Fireworks routing (default): the Fireworks gateway. Sign in with fireconnect login or use a Fireworks API key (fw_...) or Fire Pass key (fpk_...).
• Fireworks on Microsoft Foundry: models in your Azure subscription, billed through Azure. See Microsoft Foundry.

New here? Install and sign in below, then open the harness guide for the tool you use. Try the side-by-side demo if you want to compare before switching.

Prerequisites

• A Fireworks API key (fw_...) or Fire Pass key (fpk_...) for direct routing
• For Foundry: Azure resource, API key, and deployment. See portal setup.
• Node.js 18+
• At least one supported harness installed locally

Install

curl -fsSL https://raw.githubusercontent.com/fw-ai/fireconnect/main/install.sh | bash
fireconnect login

The installer clones the CLI to ~/.fireconnect/cli, installs dependencies, and adds ~/.local/bin/fireconnect. It does not sign you in or write harness settings.

After login, open your harness guide and run fireconnect <harness> on. You can also pass --api-key or set FIREWORKS_API_KEY instead of login.

Upgrade FireConnect

fireconnect upgrade

Or re-run the install curl above. On v0.9.0+, your harness stays connected; no need to run off first.

Check the installed version with fireconnect --version. For older releases and CLI renames, see CLI reference: Migration.

Sign in

fireconnect login     # browser sign-in or paste a key
fireconnect logout    # clear stored credentials
fireconnect status    # sign-in state and key storage

Fire Pass keys (fpk_...) work during login or on. FireConnect detects the key type and applies the correct defaults.

See CLI reference: Sign in options for --with-token, --account, logout --revoke, and configure.

Choose your harness

After install and sign-in, open the guide for the tool you use. Each page covers on / off, models, and harness-specific notes.

Notes

• Foundry: not on Claude Code yet.
• Fire Pass: not on Codex or Foundry. FireConnect rejects --model firerouter with a Fire Pass (fpk_...) key on every harness; use an fw_... account key for FireRouter.
• FireRouter: Cursor and Deep Agents need workspace BYOK.
• Web search MCP: any harness via HTTP MCP; FireConnect auto-install is Claude Code only today. See WebSearch MCP.
• Cursor / VS Code: quit the IDE before on or off. status is read-only.

FireRouter

FireRouter automatically routes simple requests to cheaper open models and hard requests to Claude Opus 4.8. In FireConnect, select it like any other model:

fireconnect <harness> on --model firerouter

Requires a standard Fireworks key (fw_...), not Fire Pass. Cursor and Deep Agents also need workspace BYOK. See the FireRouter overview and Harness support.
