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.
This code can reach further than it looks
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:
SUPABASE_URL (https://<ref>.supabase.co of your own project), SUPABASE_ANON_KEY (The anon (publishable) key. Never the service_role key: the server refuses it.), EKWO_EMAIL (The user the agent acts as), EKWO_PASSWORD (That user's password), EKWO_ACCESS_TOKEN (An access token, instead of email and password), EKWO_DB_URL (Direct Postgres connection, for a self-hosted database without PostgREST), EKWO_ACT_AS_USER_ID (Required with EKWO_DB_URL: the auth.users id the server acts for), EKWO_EINVOICE_DIRECTORY (Optional: the folder electronic invoices are sent to. Unset, they are issued and kept, and not sent).
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.
