Troubleshooting

"command not found" — Install Node.js 18+: nodejs.org

"Failed to connect" — Try running the server manually to see error output:

SHIPSAVING_APP_KEY=sk_your_app_key npx -y shipsaving-mcp

If it hangs (waiting for input), the server started successfully. If it errors immediately, you'll see the issue.

To clear the npx cache:

rm -rf ~/.npm/_npx
