Cursor Bridge – Run Unlimited Claude Code on Your Cursor Subscription

Summary

One binary. Claude Code on Cursor's backend. Zero config. You have a Cursor subscription. You want to use Claude Code (the CLI). Cursor's Auto model is included with your subscription — free, unlimited, no extra per-token cost. Without cursor-bridge, you'd pay separately for Anthropic API credits or a Claude Pro plan. With cursor-bridge, you just run cursor-bridge and it works — Claude Code runs on your Cursor backend. Use cases: You're already paying for Cursor → get Claude Code for free on top You want Claude Code's agent capabilities (file editing, shell commands, tool use) without Anthropic billing Cursor's Auto model is free and unlimited with subscription — Claude Code becomes effectively free to run cursor-bridge # interactive session cursor-bridge "refactor this file" # one-shot prompt cursor-bridge -p "list files" # pipe mode That's it. No proxy management. No env vars. Everything automatic. cursor-bridge (Rust binary) ├── Starts a local HTTP proxy on a random port ├── Reads your Cursor auth token from macOS keychain (or CURSOR_TOKEN env var on Linux) ├── Spawns `claude` with env vars pointing at the proxy ├── Proxy translates Anthropic API calls → Cursor agent CLI └── Cleans up on exit You don't see the proxy. You don't manage it. It's there and gone. # Prerequisites # - Cursor installed with `agent` CLI authenticated (`agent login`) # - Claude Code installed (`curl -O https://claude-code.anthropic.com/claude && chmod +x claude`) cargo install cursor-bridge # Then just use it cursor-bridge Or download a binary from Releases. macOS or Linux Cursor subscription (with agent CLI in PATH) Claude Code CLI (claude in PATH) macOS: token auto-read from keychain Linux: set CURSOR_TOKEN env var (no keychain fallback) How it differs from other proxies All other solutions are background servers you manage. cursor-bridge is a command you run. Existing proxies (cursor-api-proxy, cursor-composer-in-claude, cursor-proxy) are Node.js servers that live in your process list, ...
