Variable	Required	Description
`METABASE_API_KEY`	Yes	Metabase API key (created in Admin settings > Authentication > API keys) Docs.

Locate your Metabase instance: Note your instance hostname, e.g. acme.metabaseapp.com (Metabase Cloud) or your self-hosted domain. Every tool takes it as the required ‘host’ parameter. For local testing you can run Metabase with ‘docker run -p 3000:3000 metabase/metabase’.
Create an API key: As an admin, go to Admin settings > Authentication > API keys, create a key, and assign it to a group whose permissions cover the databases and collections you need. Copy the key (shown once, prefixed mb_).
Set the environment variable: Add the key to your .env as METABASE_API_KEY=mb_…
Verify access: Run List Databases with your hostname as the host parameter.

Metabase authenticates with an ‘x-api-key’ header
Metabase is self-hosted or tenant-hosted, so tools require a ‘host’ parameter (hostname only, HTTPS is assumed) on every call
The API key inherits the permissions of the group it is assigned to
