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? Run fireconnect login, then fireconnect claude on, restart Claude Code, and send hi. Try the side-by-side demo if you want to compare before switching.

What’s new in v0.9.0

FireConnect 0.9.0 adds a global model catalog, first-class FireRouter support, and safer upgrades:
  • Global model catalog: fireconnect model list
  • FireRouter as a model: on --model firerouter on supported harnesses
  • Claude usage reports: fireconnect claude usage
  • Web search MCP: HTTP MCP for live search with a Fireworks API key (details). FireConnect auto-install on Claude Code; other harnesses coming soon.
See Upgrade to v0.9.0 before enabling FireRouter or web search on an older install.

Harness support

Notes
  • Microsoft Foundry: Claude Code does not read --provider azure yet. Every other harness in the matrix supports Foundry routing in FireConnect v0.9.0+.
  • Fire Pass: not supported on Codex or Foundry. FireConnect also rejects --model firerouter with Fire Pass keys (fpk_...) on every harness. Use a standard Fireworks API key (fw_...) for FireRouter.
  • Web search MCP: works from any harness via HTTP MCP with a Fireworks API key (request access from Fireworks). FireConnect auto-install is Claude Code only for now; other harnesses coming soon. See WebSearch MCP.
  • Cursor / VS Code: quit the IDE before on or off (SQLite writes). status is read-only.

​
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

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. You do not have to run login first. fireconnect claude on runs sign-in inline if needed.

​
Upgrade to v0.9.0

Re-run the install script to upgrade FireConnect.
If Claude Code was connected, the installer temporarily restores your original settings. Reconnect after upgrade:
For CI, set FIRECONNECT_AUTO_OFF_CLAUDE=1 to skip prompts. Check version with fireconnect --version. After upgrading, see the v0.9.0 guides: CLI reference, recommended models, side-by-side demo, and WebSearch MCP.

​
Sign in

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.

​
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:
Cursor does not support FireRouter. See the FireRouter overview for auth, routing preferences, and supported harnesses.
