Troubleshooting

If you see “Unknown command: claude” or “command not found”:
  1. Verify installation:
  2. Check npm global bin directory:
    The claude command should be in {prefix}/bin/
  3. Add to PATH (if needed): On macOS/Linux, add to ~/.zshrc, ~/.bashrc, or ~/.config/fish/config.fish:
    Then restart your terminal or run source ~/.zshrc
  4. Reinstall if needed:
  • Verify the config file path is correct
  • Check JSON syntax (no trailing commas)
  • Restart the CLI
  • Verify your API key is correct
  • Ensure the header is danube-api-key (lowercase)
  • Check that the API key hasn’t expired or been revoked
For the best experience with Claude Code CLI and Danube, we recommend adding the Agent Skill. The Agent Skill teaches Claude how to effectively discover and use tools through the Danube MCP Server, providing better tool discovery patterns, authentication handling, and workflow guidance.
