## Introduction

This guide walks you through connecting Instacart to Google ADK using the Composio tool router. By the end, you'll have a working Instacart agent that can create a shoppable recipe page for lasagna, generate a grocery list for a vegan dinner, find grocery stores near 90210 in the us through natural language commands.
This guide will help you understand how to give your Google ADK agent real control over a Instacart account through Composio's Instacart MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Get a Instacart account set up and connected to Composio
- Install the Google ADK and Composio packages
- Create a Composio Tool Router session for Instacart
- Build an agent that connects to Instacart through MCP
- Interact with Instacart using natural language

## What is Google ADK?

Google ADK (Agents Development Kit) is Google's framework for building AI agents powered by Gemini models. It provides tools for creating agents that can use external services through the Model Context Protocol.
Key features include:
- Gemini Integration: Native support for Google's Gemini models
- MCP Toolset: Built-in support for Model Context Protocol tools
- Streamable HTTP: Connect to external services through streamable HTTP
- CLI and Web UI: Run agents via command line or web interface

## What is the Instacart MCP server, and what's possible with it?

The Instacart MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to Instacart's shopping and recipe platform. It provides structured and secure access to Instacart's APIs, so your agent can create shoppable lists, generate recipe pages, and discover nearby retailers on your behalf.
- Instant shoppable list creation: Ask your agent to generate a shareable Instacart shopping list page from a set of grocery items or meal plans.
- Recipe page generation: Have your agent create a recipe page on Instacart, complete with a unique URL for easy sharing and shopping.
- Nearby retailer discovery: Let your agent find available Instacart retailers in your area based on postal code and country code, so you always know where to shop.
- Shareable shopping experiences: Generate URLs for both shopping lists and recipes, making it simple to share curated grocery plans with friends, family, or colleagues.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `INSTACART_CREATE_INSTACART_RECIPE_LINK` | Create Instacart Recipe Link | Create an Instacart link to the shopping list of ingredients for a recipe. This action generates a shareable Instacart URL that allows users to purchase all recipe ingredients with one click. Use this when you have a recipe with ingredients and want to enable easy grocery shopping through Instacart. |
| `INSTACART_CREATE_RECIPE_PAGE` | Create Recipe Page | Create a shareable recipe page on Instacart and return the URL. This action generates an Instacart recipe page where users can: - View the recipe with ingredients, instructions, and image - Add all recipe ingredients to their cart with one click - Select their preferred nearby store for shopping Use this for meal planning apps, recipe blogs, cooking assistants, or any application that wants to enable easy grocery shopping from recipes. The returned URL can be shared via email, SMS, or social media. |
| `INSTACART_CREATE_SHOPPING_LIST_PAGE` | Create Shopping List Page | Create a shareable Shopping List Page on Instacart. This action generates a public Instacart URL where users can view a list of products, select their preferred store, and add items to their cart for delivery or pickup. The generated link can be shared via email, messaging apps, or embedded in websites. Use cases: - Share grocery lists with family members - Create shopping lists for recipes or meal plans - Enable one-click shopping for recommended products |
| `INSTACART_GET_NEARBY_RETAILERS` | Get Nearby Retailers | Retrieves a list of grocery retailers available for delivery or pickup in a given postal code area. Use this action to discover which retailers (e.g., Safeway, Walmart, Publix) are available before creating shopping lists or recipe pages. The returned retailer_key values can be used with other Instacart actions like create_shopping_list_page or create_recipe_page. Supports United States (US) and Canada (CA) postal codes. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Instacart MCP server is an implementation of the Model Context Protocol that connects your AI agent to Instacart. It provides structured and secure access so your agent can perform Instacart operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- A Google API key for Gemini models
- A Composio account and API key
- Python 3.9 or later installed
- Basic familiarity with Python

### 1. Getting API Keys for Google and Composio

Google API Key
- Go to [Google AI Studio](https://aistudio.google.com/app/apikey) and create an API key.
- Copy the key and keep it safe. You will put this in GOOGLE_API_KEY.
Composio API Key and User ID
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Go to Settings → API Keys and copy your Composio API key. Use this for COMPOSIO_API_KEY.
- Decide on a stable user identifier to scope sessions, often your email or a user ID. Use this for COMPOSIO_USER_ID.

### 2. Install dependencies

Inside your virtual environment, install the required packages.
What's happening:
- google-adk is Google's Agents Development Kit
- composio connects your agent to Instacart via MCP
- python-dotenv loads environment variables
```bash
pip install google-adk composio python-dotenv
```

### 3. Set up ADK project

Set up a new Google ADK project.
What's happening:
- This creates an agent folder with a root agent file and .env file
```bash
adk create my_agent
```

### 4. Set environment variables

Save all your credentials in the .env file.
What's happening:
- GOOGLE_API_KEY authenticates with Google's Gemini models
- COMPOSIO_API_KEY authenticates with Composio
- COMPOSIO_USER_ID identifies the user for session management
```bash
GOOGLE_API_KEY=your-google-api-key
COMPOSIO_API_KEY=your-composio-api-key
COMPOSIO_USER_ID=your-user-id-or-email
```

### 5. Import modules and validate environment

What's happening:
- os reads environment variables
- Composio is the main Composio SDK client
- GoogleProvider declares that you are using Google ADK as the agent runtime
- Agent is the Google ADK LLM agent class
- McpToolset lets the ADK agent call MCP tools over HTTP
```python
import os
import warnings

from composio import Composio
from dotenv import load_dotenv
from google.adk.agents.llm_agent import Agent
from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset

load_dotenv()

warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*")

GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY")
COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY")
COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID")

if not GOOGLE_API_KEY:
    raise ValueError("GOOGLE_API_KEY is not set in the environment.")
if not COMPOSIO_API_KEY:
    raise ValueError("COMPOSIO_API_KEY is not set in the environment.")
if not COMPOSIO_USER_ID:
    raise ValueError("COMPOSIO_USER_ID is not set in the environment.")
```

### 6. Create Composio client and Tool Router session

What's happening:
- Authenticates to Composio with your API key
- Declares Google ADK as the provider
- Spins up a short-lived MCP endpoint for your user and selected toolkit
- Stores the MCP HTTP URL for the ADK MCP integration
```python
composio_client = Composio(api_key=COMPOSIO_API_KEY)

composio_session = composio_client.create(
    user_id=COMPOSIO_USER_ID,
    toolkits=["instacart"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url,
print(f"Composio MCP URL: {COMPOSIO_MCP_URL}")
```

### 7. Set up the McpToolset and create the Agent

What's happening:
- Connects the ADK agent to the Composio MCP endpoint through McpToolset
- Uses Gemini as the model powering the agent
- Lists exact tool names in instruction to reduce misnamed tool calls
```python
composio_toolset = McpToolset(
    connection_params=StreamableHTTPConnectionParams(
        url=COMPOSIO_MCP_URL,
        headers={"x-api-key": COMPOSIO_API_KEY}
    )
)

root_agent = Agent(
    model="gemini-2.5-flash",
    name="composio_agent",
    description="An agent that uses Composio tools to perform actions.",
    instruction=(
        "You are a helpful assistant connected to Composio. "
        "You have the following tools available: "
        "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, "
        "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. "
        "Use these tools to help users with Instacart operations."
    ),
    tools=[composio_toolset],
)

print("\nAgent setup complete. You can now run this agent directly ;)")
```

### 8. Run the agent

Execute the agent from the project root. The web command opens a web portal where you can chat with the agent.
What's happening:
- adk run runs the agent in CLI mode
- adk web . opens a web UI for interactive testing
```bash
# Run in CLI mode
adk run my_agent

# Or run in web UI mode
adk web
```

## Complete Code

```python
import os
import warnings

from composio import Composio
from composio_google import GoogleProvider
from dotenv import load_dotenv
from google.adk.agents.llm_agent import Agent
from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset

load_dotenv()
warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*")

GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY")
COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY")
COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID")

if not GOOGLE_API_KEY:
    raise ValueError("GOOGLE_API_KEY is not set in the environment.")
if not COMPOSIO_API_KEY:
    raise ValueError("COMPOSIO_API_KEY is not set in the environment.")
if not COMPOSIO_USER_ID:
    raise ValueError("COMPOSIO_USER_ID is not set in the environment.")

composio_client = Composio(api_key=COMPOSIO_API_KEY, provider=GoogleProvider())

composio_session = composio_client.create(
    user_id=COMPOSIO_USER_ID,
    toolkits=["instacart"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url


composio_toolset = McpToolset(
    connection_params=StreamableHTTPConnectionParams(
        url=COMPOSIO_MCP_URL,
        headers={"x-api-key": COMPOSIO_API_KEY}
    )
)

root_agent = Agent(
    model="gemini-2.5-flash",
    name="composio_agent",
    description="An agent that uses Composio tools to perform actions.",
    instruction=(
        "You are a helpful assistant connected to Composio. "
        "You have the following tools available: "
        "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, "
        "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. "
        "Use these tools to help users with Instacart operations."
    ),  
    tools=[composio_toolset],
)

print("\nAgent setup complete. You can now run this agent directly ;)")
```

## Conclusion

You've successfully integrated Instacart with the Google ADK through Composio's MCP Tool Router. Your agent can now interact with Instacart using natural language commands.
Key takeaways:
- The Tool Router approach dynamically routes requests to the appropriate Instacart tools
- Environment variables keep your credentials secure and separate from code
- Clear agent instructions reduce tool calling errors
- The ADK web UI provides an interactive interface for testing and development
You can extend this setup by adding more toolkits to the toolkits array in your session configuration.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Instacart MCP?

With a standalone Instacart MCP server, the agents and LLMs can only access a fixed set of Instacart tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Instacart and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Google ADK?

Yes, you can. Google ADK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Instacart tools.

### Can I manage the permissions and scopes for Instacart while using Tool Router?

Yes, absolutely. You can configure which Instacart scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Instacart data and credentials are handled as safely as possible.
