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/genai-toolbox/releases) corresponding to your OS and CPU architecture. {{< /notice >}} ```bash export OS="linux/amd64" # one of linux/amd64, darwin/arm64, darwin/amd64, or windows/amd64 curl -O https://storage.googleapis.com/genai-toolbox/v0.26.0/$OS/toolbox ``` 1. Make the binary executable: ```bash chmod +x toolbox ``` 1. Write the following into a `tools.yaml` file. Be sure to update any fields such as `user`, `password`, or `database` that you may have customized in the previous step. {{< notice tip >}} In practice, use environment variable replacement with the format ${ENV_NAME} instead of hardcoding your secrets into the configuration file. {{< /notice >}} ```yaml kind: sources name: my-pg-source type: postgres host: 127.0.0.1 port: 5432 database: toolbox_db user: toolbox_user password: my-password --- kind: tools name: search-hotels-by-name type: postgres-sql source: my-pg-source description: Search for hotels based on name. parameters: - name: name type: string description: The name of the hotel. statement: SELECT * FROM hotels WHERE name ILIKE '%' || $1 || '%'; --- kind: tools name: search-hotels-by-location type: postgres-sql source: my-pg-source description: Search for hotels based on location. parameters: - name: location type: string description: The location of the hotel. statement: SELECT * FROM hotels WHERE location ILIKE '%' || $1 || '%'; --- kind: tools name: book-hotel type: postgres-sql source: my-pg-source description: >- Book a hotel by its ID.

Run the Toolbox server, pointing to the `tools.yaml` file created earlier: ```bash ./toolbox --tools-file "tools.yaml" ``` {{< notice note >}} Toolbox enables dynamic reloading by default. To disable, use the `--disable-reload` flag. {{< /notice >}}
