Connect a Trino cluster to Modus so its catalogs, schemas, tables, and columns become context that Modus can reason over. Modus connects read-only over TLS and stores your credentials encrypted in AWS Secrets Manager.

​
Prerequisites

Before you begin, make sure you have:
  • The host and port of your Trino coordinator (TLS, default 8443).
  • Credentials Modus can use — either a username and password, or a JWT minted by your identity provider.
  • Read access to the catalogs and schemas you want Modus to use as context.

​
Set up read-only access

Trino access control is deployment-specific, but the principle is the same: give Modus an identity that can connect, list catalogs and schemas, and SELECT from the schemas you want it to use as context — nothing more.
  • Username / password — use an existing read-only account, or create one in your Trino authentication backend (LDAP, password file, etc.).
  • JWT — configure your identity provider to mint a bearer token for the Trino coordinator; Modus derives the identity from the token.
The identity needs to run SELECT 1, SHOW CATALOGS, SHOW SCHEMAS, and SELECT on the target schemas. No write access is required.

​
Network access

If your Trino cluster is behind a firewall or security group, allow Modus’s egress IP addresses so it can reach the coordinator. See IP Allowlisting.

Connect in Modus

1

Test and save

  1. Click Test Connection to verify Modus can reach your cluster.
  2. Click Save Connection.

Select schemas

After saving, Modus lists the catalogs and schemas your identity can access. Select the ones you want Modus to use as context, then save. Nothing is scanned without your explicit selection.

Troubleshooting

​
Verification

Your Trino cluster is now connected. Modus turns the selected catalogs, schemas, tables, and columns into context so Modus can give accurate, data-aware answers. Need help? Contact us at support@getmodus.com.
Modus connects read-only and requests only the minimum permissions needed to understand and query your data. All credentials are encrypted and stored in AWS Secrets Manager — never in plaintext.
