Known issues
breakingIn version 1.5.0, the import path changed from `nvidia_nat.mcp` to `nvidia_nat_mcp`. Code using the old path will break.
fix
Update imports to `from nvidia_nat_mcp import ...`.
affects: <1.5.0
deprecatedThe `MCPServer` class constructor signature changed in 1.6.0. The `host` parameter is deprecated in favor of `server_url`.
fix
Replace `host` with `server_url` in MCPServer instantiation.
affects: >=1.6.0
gotchaThe API key is required for all MCP calls except when connecting to a localhost server in development mode.
fix
Always set `api_key` or environment variable `MCP_API_KEY`; use an empty string only for local testing.
affects: >=1.0.0
