> Developer workflow and documentation expectations for the MCP Server.

## Development checklist

1. Define the tool contract.
2. Validate inputs.
3. Implement the minimum capability.
4. Add tests.
5. Document privacy and security behavior.
6. Add examples.
7. Record the change in the changelog.

## Security

Never log secrets by default. Avoid accepting private keys or seed phrases. Treat external URLs, user-provided text, and tool outputs as untrusted input.
