{"slug": "cursor-bridge-run-unlimited-claude-code-on-your-cursor-subscription", "title": "Cursor Bridge – Run Unlimited Claude Code on Your Cursor Subscription", "summary": "A new open-source Rust binary called cursor-bridge lets Cursor subscription users run Anthropic's Claude Code CLI for free on Cursor's backend, eliminating separate API costs. The tool, available via cargo install or prebuilt binaries, automatically proxies Anthropic API calls through Cursor's agent CLI without requiring manual configuration or background daemons. Cursor-bridge is not affiliated with Anthropic or Cursor/Anysphere and is offered under the MIT license.", "body_md": "**One binary. Claude Code on Cursor's backend. Zero config.**\n\nYou have a **Cursor subscription**. You want to use **Claude Code** (the CLI).\nCursor's **Auto model** is included with your subscription — free, unlimited, no extra per-token cost.\n\nWithout cursor-bridge, you'd pay separately for Anthropic API credits or a Claude Pro plan.\nWith cursor-bridge, you just run `cursor-bridge`\n\nand it works — Claude Code runs on your Cursor backend.\n\n**Use cases:**\n\n- You're already paying for Cursor → get Claude Code for free on top\n- You want Claude Code's agent capabilities (file editing, shell commands, tool use) without Anthropic billing\n- Cursor's Auto model is free and unlimited with subscription — Claude Code becomes effectively free to run\n\n```\ncursor-bridge                         # interactive session\ncursor-bridge \"refactor this file\"    # one-shot prompt\ncursor-bridge -p \"list files\"         # pipe mode\n```\n\nThat's it. No proxy management. No env vars. Everything automatic.\n\n```\ncursor-bridge (Rust binary)\n  ├── Starts a local HTTP proxy on a random port\n  ├── Reads your Cursor auth token from macOS keychain (or CURSOR_TOKEN env var on Linux)\n  ├── Spawns `claude` with env vars pointing at the proxy\n  ├── Proxy translates Anthropic API calls → Cursor agent CLI\n  └── Cleans up on exit\n```\n\nYou don't see the proxy. You don't manage it. It's there and gone.\n\n```\n# Prerequisites\n# - Cursor installed with `agent` CLI authenticated (`agent login`)\n# - Claude Code installed (`curl -O https://claude-code.anthropic.com/claude && chmod +x claude`)\n\ncargo install cursor-bridge\n\n# Then just use it\ncursor-bridge\n```\n\nOr download a binary from Releases.\n\n**macOS** or**Linux**- Cursor subscription (with\n`agent`\n\nCLI in PATH) - Claude Code CLI (\n`claude`\n\nin PATH) **macOS**: token auto-read from keychain** Linux**: set`CURSOR_TOKEN`\n\nenv var (no keychain fallback)\n\n**All other solutions are background servers you manage. cursor-bridge is a command you run.**\n\nExisting proxies (`cursor-api-proxy`\n\n, `cursor-composer-in-claude`\n\n, `cursor-proxy`\n\n) are Node.js servers that live in your process list, occupy a port, and need manual env var wiring. They don't ship with Claude Code — they sit between you and it, adding ceremony.\n\n**cursor-bridge is the opposite.** There is nothing to start, stop, or configure. It *is* the session:\n\n| The old way | cursor-bridge |\n|---|---|\nStart a proxy daemon, note the port, set env vars, then run `claude` |\nRun `cursor-bridge` — done |\n| Background process that outlives your session | Lives and dies with your terminal |\n| Pick a port, pray it doesn't clash | Random port, zero conflicts |\n`npm install` + `npx` + Node.js runtime (60+ MB) |\nOne Rust binary, ~780 KB, statically compiled |\n| Multiple npm packages, peer deps, version mismatches | `cargo install` or download. One binary. Nothing else. |\n\nNo daemon. No `npm install`\n\n. No env vars. No port hunting. No cleanup. Just a single binary that works.\n\ncursor-bridge replaces `claude`\n\nentirely — it manages the proxy lifecycle internally, spawns the CLI, and cleans up after itself when you're done.\n\n**Linux**: requires`CURSOR_TOKEN`\n\nenv var (no keychain support).**No workspace sandboxing**— the agent runs in your current directory.** Single account**— no multi-account rotation (yet).\n\nThis project is not affiliated with Anthropic or Cursor/Anysphere.
