Installed [Node.js (v18 or higher)]. 1. Installed [PostgreSQL 16+ and the `psql` client][install-postgres]. [Node.js (v18 or higher)]: https://nodejs.org/ [install-postgres]: https://www.postgresql.org/download/ ### Cloud Setup (Optional) {{< regionInclude "quickstart/shared/cloud_setup.md" "cloud_setup" >}} ## Step 1: Set up your database {{< regionInclude "quickstart/shared/database_setup.md" "database_setup" >}} ## Step 2: Install and configure Toolbox {{< regionInclude "quickstart/shared/configure_toolbox.md" "configure_toolbox" >}} ## Step 3: Connect your agent to Toolbox In this section, we will write and run an agent that will load the Tools from Toolbox. 1. (Optional) Initialize a Node.js project: ```bash npm init -y ``` 1. In a new terminal, install the [SDK](https://www.npmjs.com/package/@toolbox-sdk/core). ```bash npm install @toolbox-sdk/core ``` 1. Install other required dependencies {{< tabpane persist=header >}} {{< tab header="LangChain" lang="bash" >}} npm install langchain @langchain/google-genai {{< /tab >}} {{< tab header="GenkitJS" lang="bash" >}} npm install genkit @genkit-ai/googleai {{< /tab >}} {{< tab header="LlamaIndex" lang="bash" >}} npm install llamaindex @llamaindex/google @llamaindex/workflow {{< /tab >}} {{< tab header="GoogleGenAI" lang="bash" >}} npm install @google/genai {{< /tab >}} {{< /tabpane >}} 1. Create a new file named `hotelAgent.js` and copy the following code to create an agent: {{< tabpane persist=header >}} {{< tab header="LangChain" lang="js" >}} {{< include "quickstart/js/langchain/quickstart.js" >}} {{< /tab >}} {{< tab header="GenkitJS" lang="js" >}} {{< include "quickstart/js/genkit/quickstart.js" >}} {{< /tab >}} {{< tab header="LlamaIndex" lang="js" >}} {{< include "quickstart/js/llamaindex/quickstart.js" >}} {{< /tab >}} {{< tab header="GoogleGenAI" lang="js" >}} {{< include "quickstart/js/genAI/quickstart.js" >}} {{< /tab >}} {{< /tabpane >}} 1. Run your agent, and observe the results: ```sh node hotelAgent.js ``` {{< notice info >}} For more information, visit the [JS SDK repo](https://github.com/googleapis/mcp-toolbox-sdk-js). {{</ notice >}}
