carto-connect-datawarehouse

When to use this skill

• The user wants to connect a new warehouse to CARTO.
• The user is debugging a connection (auth failures, missing tables, permission errors).
• A downstream skill needs a connection name and you don't yet know which engine the user has.
• The user is rotating credentials or moving from one project/database to another.

Quick lifecycle

carto connections list --json             # what's already connected?
carto connections get <id>                # detailed view of one connection
carto connections create                  # interactive create
carto connections update <id>             # rotate credentials, change scoping
carto connections delete <id>             # remove (irreversible)

Choosing an engine

If the user already has a connection (

connections list

returns at least one), don't push a new one — use the existing one.

Listing options

carto connections list                    # default page (10)
carto connections list --all              # all pages
carto connections list --search "prod"    # filter by name
carto connections list --json             # machine-readable

Common pitfalls

• Auth-mode mismatch: BigQuery supports OAuth (interactive) and service-account JSON (CI). Pick one consistently per environment; mixing the two breaks shared connections.
• Region vs project: Some engines need both an account/project and a region (Snowflake, Redshift). Skipping the region typically yields "endpoint not found" rather than a permissions error.
• Default database/schema scoping: CARTO can write tilesets, named sources, and analytics output back into the warehouse. Confirm with the user which dataset/schema CARTO is allowed to write to before creating the connection.
• Permissions for

  and table reads come from the credential CARTO holds, not from the user's CARTO role. A CARTO Admin with a low-privilege service account will still see "permission denied" from the warehouse.
