**Description:** Database Universal MCP server provides AI assistants with access to PostgreSQL, MySQL, MariaDB, and Oracle databases. It supports natural-language SQL queries through a single connection string or component fields.

**Configuration Parameters:**

* **Connection String (DSN)** (sensitive) (use this OR the fields below) - Full DSN, e.g. `postgres://user:pass@host:5432/db`. Use either this or the component fields below.
* **Database Type** (optional) - `postgres`, `mysql`, `mariadb`, or `oracle`.
* **Database Host** (optional) - Database hostname.
* **Database Port** (optional) - Database port. Defaults to the standard port for the chosen type.
* **Database User** (optional) - Database username.
* **Database Password** (sensitive) (optional) - Database password.
* **Database Name** (optional) - Database name.
* **Read-only** (optional) - Set to `true` to disable writes (recommended for first-time setup).

**Setup Steps:**

1. Identify the database user that the MCP server will connect as. Read-only access is strongly recommended for initial deployments.
2. Either compose the full DSN or note the host/port/user/password/database fields separately.
3. When creating the connection in Natoma, enter the DSN (or the component fields) and save.
