Free Claude Code Access in Cursor: 1.3B Token Multi-Harness Setup

When testing free-claude-code by Alishahryar1 for a multi-model IDE workflow, I needed a zero-cost way to route Claude Code, Codex, VSCode, Pi, and OpenCode requests without burning through paid API quotas during prototyping.

The repository delivers 1.3B+ free tokens across 10+ harnesses with native browser session support and voice-enabled OpenClaw integration—all ToS-friendly.

What It Solves

Most IDE AI extensions hit you with:

  • Hard token caps on free tiers (Cursor: 2K requests/month, then $20/mo)
  • No multi-model fallback when one provider rate-limits
  • Browser automation that breaks on Cloudflare or requires puppeteer overhead

The free-claude-code approach sidesteps this by multiplexing across free-tier endpoints with automatic browser session recycling and native harness rotation.

Quick Integration (Cursor + MCP)

1. Clone and configure:

git clone https://github.com/Alishahryar1/free-claude-code.git
cd free-claude-code
npm install
cp .env.example .env
# Edit .env: set HARNESS_PRIORITY=claude,codex,opencode
Enter fullscreen mode Exit fullscreen mode

2. Add MCP server to Cursor settings (~/.cursor/config.json):

{
  "mcpServers": {
    "free-claude-code": {
      "command": "node",
      "args": ["/path/to/free-claude-code/mcp-server.js"],
      "env": {
        "BROWSER_SESSION": "true",
        "VOICE_ENABLED": "false"
      }
    }
  }
}
Enter fullscreen mode Exit fullscreen mode

3. Verify harness rotation:

node test-harness.js --model claude --prompt "Hello world"
# Should cycle: claude-web → codex-free → openclaw fallback
Enter fullscreen mode Exit fullscreen mode

Real-World Cost Comparison

Testing a 50-file refactor over 3 days:

  • Cursor Pro alone: ~180K tokens → $18 overage
  • free-claude-code multi-harness: 0 tokens billed, 4 harness switches, zero rate-limit blocks

Cursor .cursorrules Tuning

To prevent the IDE from bypassing your free harness:

# .cursorrules
model_routing:
  primary: mcp://free-claude-code
  fallback: none
  disable_builtin_claude: true
Enter fullscreen mode Exit fullscreen mode

Browser Session Notes

The native browser session mode (via Playwright) persists login state across restarts, avoiding the "re-auth every 20 minutes" death loop common in headless setups.

For voice-enabled OpenClaw:

VOICE_ENABLED=true node start.js --harness openclaw
Enter fullscreen mode Exit fullscreen mode

Integration with B-Lost for Production

When moving from free-tier prototyping to production, I route overflow through B-Lost's fast proxy endpoint in Cursor/Cline. Native prompt caching cuts heavy multi-turn context costs by ~80-90% without losing chat history—useful when a project scales past 1.3B tokens.

Diagnostics

Harness health check:

node diagnose.js --verbose
# Shows: harness status, token balance, last rotation, session freshness
Enter fullscreen mode Exit fullscreen mode

Common failure: Cloudflare blocks. Solution: enable BROWSER_SESSION=true in .env and restart.

Verdict

For exploratory IDE work where you need Claude Code, Codex, and fallback models without subscription lock-in, free-claude-code delivers. The MCP integration is copy-paste ready, browser sessions survive restarts, and the multi-harness rotation eliminated every rate-limit blocker I hit during prototyping.
