Troubleshooting & Common ErrorsFAQ

Common connection errors and verified fixes for ArcBounty

Getting 'connection closed' or exit code 1 in Cursor / Claude Code for ArcBounty?

Usually caused by missing runtime paths or IDE environment inheritance. Fix steps: 1. Verify Node.js 18+ (npx) or Python 3.10+ (uvx) is installed; 2. Run 'which npx' or 'which uvx' in terminal, and replace 'command' with absolute path; 3. Reload or restart the client window after modifying config.

Fix Snippet
# Check binary path in terminal:
which npx
node -v
Getting 'spawn npx ENOENT' or 'command not found'?

The editor background process does not inherit your full terminal PATH. Solution: Globally install the package, or set the absolute binary path (e.g. C:\Program Files\nodejs\npx.cmd on Windows, or /usr/local/bin/npx on macOS).

Missing required environment variable or authentication failure?

ArcBounty requires environment variables (ARC_NETWORK、BOUNTY_ADAPTER_ADDRESS、ARC_RPC_URL、AGENT_PRIVATE_KEY、CIRCLE_API_KEY、ENTITY_SECRET、CIRCLE_WALLET_ID、CIRCLE_WALLET_ADDRESS、ARCBOUNTY_MAX_REWARD_USDC、ARCBOUNTY_MAX_SPEND_USDC). Ensure you have added valid keys under the 'env' object in your config file without trailing whitespace.

Fix Snippet
// .cursor/mcp.json 或 claude_desktop_config.json
{
  "env": {
    "API_KEY": "your_actual_key_here"
  }
}
