## Integration rules

- REST V2 uses form fields; DVS uses POST JSON with user and user_access_token.
- Discover organization-specific project, user and dropdown IDs before writing DVS tasks.
- MCP provides read-only file access and public documentation. It does not create or update DVS tasks.
- Use the protocol-specific authentication in each reference; never include credentials in URLs.
