Frequently asked questions

What is the default transport mode?

The server runs in SSE (Server-Sent Events) mode by default. You can switch to STDIO mode using the `--transport stdio` argument.

What environment variables are required?

`HOLOGRES_USER`, `HOLOGRES_PASSWORD`, and `HOLOGRES_DATABASE` are required. `SERVER_HOST` and `SERVER_PORT` are only needed for SSE mode.

What system resources are available for monitoring?

System resource templates expose `missing_stats_tables`, `stat_activity`, `query_log/latest/<row_limits>`, and query logs filtered by user or application.

Can it be integrated with Cherry Studio?

Yes. For SSE mode, use the server’s host and port (e.g., `http://localhost:8001`). For STDIO mode, configure the command and arguments as shown in the README.

What Python version is required?

Python 3.10 or higher is required, along with the `uv` package manager for development.
