MCP Haystack Google Maps

🚀 MCP Grabbing Straws Demonstration

An implementation of Haystack integrated with an MCP server, with a focus on the integration of the Google Maps API.

🚀 Quick Start

Check out the demonstration notebook for a complete example that shows how to connect to the Google Maps MCP server.

Run the Google Maps MCP Server

docker run -it --rm -p 8000:8000 -e GOOGLE_MAPS_API_KEY=$GOOGLE_MAPS_API_KEY supercorp/supergateway \
    --stdio "npx -y @modelcontextprotocol/server-google-maps" \
    --port 8000

Connect to the Server

from haystack.tools import MCPServer, SSEServerInfo
from haystack.components.tools import ToolInvoker

# Create server information
server_info = SSEServerInfo(
    base_url="http://localhost:8000",
)

# Create the MCP server toolset
mcp_server = MCPServer(server_info=server_info)

# Use the toolset with the ToolInvoker or ChatGenerator component
invoker = ToolInvoker(tools=mcp_server)

✨ Features

• Connect to a remote MCP server using SSE (Server-Sent Events).
• Dynamically discover and load available tools.
• Seamlessly integrate with Haystack pipelines.

📦 Installation

Overview

This project implements MCPServer, a Haystack Toolset used to connect to a remote MCP server and dynamically load available tools. This implementation is based on the recently added Toolset abstraction in Haystack (https://github.com/deepset-ai/haystack/pull/9161).
