+If you plan to use **Google Cloud’s Vertex AI** with your agent (e.g., using
+`vertexai=True` or a Google GenAI model), follow these one-time setup steps for
+local development:
+
+1. [Install the Google Cloud CLI](https://cloud.google.com/sdk/docs/install)
+1. [Set up Application Default Credentials
+   (ADC)](https://cloud.google.com/docs/authentication/set-up-adc-local-dev-environment)
+1. Set your project and enable Vertex AI
+
+    ```bash
+    gcloud config set project YOUR_PROJECT_ID
+    gcloud services enable aiplatform.googleapis.com

+In this section, we will download Toolbox, configure our tools in a
+`tools.yaml`, and then run the Toolbox server.
+
+1.  Download the latest version of Toolbox as a binary:
+
+    {{< notice tip >}}
+    Select the
+    [correct binary](https://github.com/googleapis/mcp-toolbox/releases)
+    corresponding to your OS and CPU architecture.

+
+1.  [Optional] Verify the downloaded binary's authenticity and integrity:
+
+    We recommend verifying the digital signature of the downloaded binary before running it.

+In this section, we will create a database, insert some data that needs to be
+accessed by our agent, and create a database user for Toolbox to connect with.
+
+1. Connect to postgres using the `psql` command:
+
+    ```bash
+    psql -h 127.0.0.1 -U postgres
+    ```
+
+    Here, `postgres` denotes the default postgres superuser.
+
+    {{< notice info >}}
+
+#### **Having trouble connecting?**
+
+* **Password Prompt:** If you are prompted for a password for the `postgres`
+  user and do not know it (or a blank password doesn't work), your PostgreSQL
+  installation might require a password or a different authentication method.
+* **`FATAL: role "postgres" does not exist`:** This error means the default
+  `postgres` superuser role isn't available under that name on your system.
+* **`Connection refused`:** Ensure your PostgreSQL server is actually running.
+  You can typically check with `sudo systemctl status postgresql` and start it
+  with `sudo systemctl start postgresql` on Linux systems.
+
+<br/>
+
+#### **Common Solution**
+
+For password issues or if the `postgres` role seems inaccessible directly, try
+switching to the `postgres` operating system user first. This user often has
+permission to connect without a password for local connections (this is called
+peer authentication).
+
+```bash
+sudo -i -u postgres
+psql -h 127.0.0.1
+```
+
+Once you are in the `psql` shell using this method, you can proceed with the
+database creation steps below. Afterwards, type `\q` to exit `psql`, and then
+`exit` to return to your normal user shell.
+
+If desired, once connected to `psql` as the `postgres` OS user, you can set a
+password for the `postgres` *database* user using: `ALTER USER postgres WITH
+PASSWORD 'your_chosen_password';`. This would allow direct connection with `-U
+postgres` and a password next time.
+    {{< /notice >}}
+
+1. Create a new database and a new user:
+
+    {{< notice tip >}}
+  For a real application, it's best to follow the principle of least permission
+  and only grant the privileges your application needs.
+    {{< /notice >}}
+
+    ```sql
+      CREATE USER toolbox_user WITH PASSWORD 'my-password';
+
+      CREATE DATABASE toolbox_db;
+      GRANT ALL PRIVILEGES ON DATABASE toolbox_db TO toolbox_user;
+
+      ALTER DATABASE toolbox_db OWNER TO toolbox_user;
+    ```
+
+1. End the database session:
+
+    ```bash
+    \q
+    ```
+
+    (If you used `sudo -i -u postgres` and then `psql`, remember you might also
+    need to type `exit` after `\q` to leave the `postgres` user's shell
+    session.)
+
+1. Connect to your database with your new user:
+
+    ```bash
+    psql -h 127.0.0.1 -U toolbox_user -d toolbox_db
+    ```
+
+1. Create a table using the following command:
+
+    ```sql
+    CREATE TABLE hotels(
+      id            INTEGER NOT NULL PRIMARY KEY,
+      name          VARCHAR NOT NULL,
+      location      VARCHAR NOT NULL,
+      price_tier    VARCHAR NOT NULL,
+      checkin_date  DATE    NOT NULL,
+      checkout_date DATE    NOT NULL,
+      booked        BIT     NOT NULL
+    );
+    ```
+
+1. Insert data into the table.
+
+    ```sql
+    INSERT INTO hotels(id, name, location, price_tier, checkin_date, checkout_date, booked)
+    VALUES
+      (1, 'Hilton Basel', 'Basel', 'Luxury', '2024-04-22', '2024-04-20', B'0'),
+      (2, 'Marriott Zurich', 'Zurich', 'Upscale', '2024-04-14', '2024-04-21', B'0'),
