 #### Notes
-- **Docs-host mode** - Docs-host mode has been disabled and will be removed in a future release. Its original purpose has been superseded by the move to MCP server resources.
 - **HTTP transport mode** - By default, the server uses `stdio`. Use the `--http` flag to enable HTTP transport.
 - **Logging** - The server uses a `diagnostics_channel`-based logger that keeps STDIO stdout pure by default.
 - **Programmatic API** - The server can also be used programmatically with options. See [Programmatic Usage](#programmatic-usage) for more details.
