Installation

Install from PyPI:

pip install ai-boutique-assit-mcp

Or install from source:

git clone https://github.com/arjunprabhulal/ai-boutique-assit-mcp.git
cd ai-boutique-assit-mcp
pip install -e .

Usage

1. Start MCP Server

The server supports two modes of operation:

HTTP Mode (Web/API Access)

# Standalone HTTP server (default)
boutique-mcp-server --port 8080

# Or explicitly force HTTP mode
boutique-mcp-server --http --port 8081

Stdio Mode (ADK Integration)

# Force stdio mode for direct ADK integration
boutique-mcp-server --stdio

# ADK will automatically launch in stdio mode when using StdioConnectionParams

Available Options

boutique-mcp-server --help

# Options:
#   --port PORT    Port for HTTP mode (default: 8080)
#   --stdio        Force stdio mode (for ADK integration)
#   --http         Force HTTP mode (for web/API access)

2. Connect with ADK Agent

HTTP Connection (Manual Server Start)

from google.adk.agents import Agent
from google.adk.tools.mcp_tool import McpToolset, SseConnectionParams

agent = Agent(
    name="boutique_assistant",
    model="gemini-2.0-flash",
    instruction="You are a helpful e-commerce assistant.",
    tools=[
        McpToolset(
            connection_params=SseConnectionParams(
                url="http://localhost:8081/mcp"
            )
        )
    ]
)

Stdio Connection (Automatic Server Launch)

from google.adk.agents import Agent
from google.adk.tools.mcp_tool import McpToolset, StdioConnectionParams, StdioServerParameters

agent = Agent(
    name="boutique_assistant", 
    model="gemini-2.0-flash",
    instruction="You are a helpful e-commerce assistant.",
    tools=[
        McpToolset(
            connection_params=StdioConnectionParams(
                server_params=StdioServerParameters(
                    command="boutique-mcp-server",
                    args=["--stdio"],
                    env={
                        "PRODUCT_CATALOG_SERVICE": "localhost:3550",
                        "CART_SERVICE": "localhost:7070",
                        # Add other service endpoints as needed
                    }
                )
            )
        )
    ]
)

Configuration

Environment Variables

The server connects to Online Boutique microservices using these default endpoints (Kubernetes service names):

# Default endpoints (production/GKE environment)
PRODUCT_CATALOG_SERVICE="productcatalogservice:3550"
CART_SERVICE="cartservice:7070"
RECOMMENDATION_SERVICE="recommendationservice:8080"
SHIPPING_SERVICE="shippingservice:50051"
CURRENCY_SERVICE="currencyservice:7000"
PAYMENT_SERVICE="paymentservice:50051"
EMAIL_SERVICE="emailservice:5000"
CHECKOUT_SERVICE="checkoutservice:5050"
AD_SERVICE="adservice:9555"

For local testing, override with localhost endpoints:

export PRODUCT_CATALOG_SERVICE="localhost:3550"
export CART_SERVICE="localhost:7070"
export RECOMMENDATION_SERVICE="localhost:8080"
export SHIPPING_SERVICE="localhost:50051"
export CURRENCY_SERVICE="localhost:7000"
export PAYMENT_SERVICE="localhost:50052"
export EMAIL_SERVICE="localhost:5000"
export CHECKOUT_SERVICE="localhost:5050"
export AD_SERVICE="localhost:9555"
