What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

This one needs environment variables set before it will start:
N3FJP_HOST (N3FJP API host.), N3FJP_PORT (N3FJP API port (Settings → Application Program Interface). Default 1100. Not the multi-PC networking port.), N3FJP_TIMEOUT (Seconds to wait for an N3FJP response.), N3FJP_ALLOW_DB_WIPE (DANGER. When off (default), raw SQL that could delete/overwrite the entire log (DROP/TRUNCATE, unscoped DELETE/UPDATE) is refused. Only enable with a backup and full understanding of the risk.).
The author declared them in the registry entry; get the values from the project itself.
