Model Context Protocol MCP Demo With Langchain MCP ADAPTERS Ollama
What is MCP Server?
The MCP Server acts as a translator layer that allows LLMs to interact with external services (like math operations or weather data) in a standardized way. It converts service functionality into a format that LLMs can understand and use.How to use MCP Server?
1. Start the desired MCP server (math or weather) 2. Connect your LLM application via the MCP client 3. The server will advertise available tools 4. Your LLM can now use these tools through standardized requestsUse Cases
- Building AI assistants that need real-world data - Creating workflows that combine LLMs with existing APIs - Developing applications where LLMs need to perform calculations - Integrating LLMs with business databases securelyKey Features
Standardized Interface
Provides a consistent way for LLMs to interact with diverse services, similar to how REST standardized web services.
Multi-Service Support
Can connect to multiple services simultaneously (demonstrated in multiclient.py).
LangChain Integration
Works seamlessly with LangChain framework through langchain-mcp-adapters.
Advantages
Simplifies integration of LLMs with real-world tools
Reduces maintenance overhead with standardized protocol
Future-proof architecture that supports new services
Open-source and extensible
Limitations
Requires setup of server components
Currently has limited pre-built integrations
Performance depends on underlying service response times
Getting Started
Install Requirements
Ensure you have Python installed along with required packages (LangChain, Ollama).
Start Servers
Launch the desired MCP servers in separate terminal windows.
Run Client
Execute either the single-service client or multi-service client.
Example Scenarios
Financial Calculation
An AI assistant helping with shopping calculations
Travel Planning
Checking weather for trip planning
