JS Quickstart (Local)

Before you begin

This guide assumes you have already done the following:

1. Installed Node.js (v18 or higher).
2. Installed PostgreSQL 16+ and the psql client.

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 MCP Toolbox

{{< regionInclude "quickstart/shared/configure_toolbox.md" "configure_toolbox" >}}

Step 3: Connect your agent to MCP Toolbox

In this section, we will write and run an agent that will load the Tools from MCP Toolbox.

1. (Optional) Initialize a Node.js project:

   bashCopy

   npm init -y
   

2. In a new terminal, install the SDK package. {{< tabpane persist=header >}} {{< tab header="LangChain" lang="bash" >}} npm install @toolbox-sdk/core {{< /tab >}} {{< tab header="GenkitJS" lang="bash" >}} npm install @toolbox-sdk/core {{< /tab >}} {{< tab header="LlamaIndex" lang="bash" >}} npm install @toolbox-sdk/core {{< /tab >}} {{< tab header="GoogleGenAI" lang="bash" >}} npm install @toolbox-sdk/core {{< /tab >}} {{< tab header="ADK" lang="bash" >}} npm install @toolbox-sdk/adk {{< /tab >}} {{< /tabpane >}}

3. 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 >}} {{< tab header="ADK" lang="bash" >}} npm install @google/adk {{< /tab >}} {{< /tabpane >}}

4. 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 >}}

{{< tab header="ADK" lang="js" >}}

{{< include "quickstart/js/adk/quickstart.js" >}}

{{< /tab >}}

{{< /tabpane >}}

1. Run your agent, and observe the results:

   shCopy

   node hotelAgent.js
