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.
return await this.spawn(specifier);
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.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 5 min ago.

This one needs environment variables set before it will start:
ZOTERO_API_KEY (Zotero API key (writes/sync/groups; optional for local-only reads).), ZOTEUS_LOCAL (Use the Zotero desktop local API: auto | on | off.), ZOTEUS_ALLOW_DELETE (Set to true to enable permanent deletion (off by default).).
The author declared them in the registry entry; get the values from the project itself.
This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.
