   • utils.ts: Utilities for your tools
3. Add your tool to the list of available tools in src/main.ts
4. Add documentation for your tool in the README.md
5. Add examples of how to use your tool in examples.md
6. Write tests for your tool

Project Structure

The Base MCP server follows this structure for tools:

src/
├── tools/
│   ├── [TOOL_NAME]/ <-- ADD DIR HERE
│   │   ├── index.ts (defines and exports tools)

Security Considerations

• The configuration file contains sensitive information (API keys and seed phrases). Ensure it's properly secured and not shared.
• Consider using environment variables or a secure credential manager instead of hardcoding sensitive information.
• Be cautious when transferring funds or deploying contracts, as these operations are irreversible on the blockchain.
• When using the onramp functionality, ensure you're on a secure connection.
• Verify all transaction details before confirming, especially when transferring funds or buying credits.

Troubleshooting

If you encounter issues:

1. Check that your Coinbase API credentials are correct
2. Verify that your seed phrase is valid
3. Ensure you're on the correct network (Base Mainnet)
4. Check the Claude Desktop logs for any error messages
