How to Set Up and Use MCP Mastery

MCP Mastery with Claude and LangChain is a comprehensive educational repository covering how to build MCP servers and clients using Python, Streamlit, ChromaDB, LangChain, LangGraph agents, and Ollama local LLMs. It provides hands-on course materials, code examples, and project templates for developers who want to learn the Model Context Protocol in depth alongside modern AI application patterns. The repository accompanies a structured course and is ideal for engineers moving from basic LLM usage to building production-grade agentic systems.

Prerequisites

  • Python 3.10 or later installed
  • Anthropic API key for Claude integration
  • Ollama installed locally if using local LLM examples
  • Basic familiarity with Python async programming and REST APIs
  • An MCP-compatible client such as Claude Desktop for testing built servers
1

Clone the repository

Clone the course repository to your local machine.

git clone https://github.com/laxmimerit/MCP-Mastery-with-Claude-and-Langchain.git
cd MCP-Mastery-with-Claude-and-Langchain
2

Create a virtual environment

Set up a Python virtual environment to isolate course dependencies.

python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
3

Install dependencies

Install the required Python packages for the course examples.

pip install -r requirements.txt
4

Set API keys

Export your Anthropic API key and any other required keys as environment variables.

export ANTHROPIC_API_KEY=your_anthropic_api_key
5

Explore and run individual modules

The repo is organized into topic modules covering MCP servers, LangChain agents, LangGraph workflows, ChromaDB vector stores, and Streamlit UIs. Navigate into the relevant module directory and run the example scripts.

# Example: run a basic MCP server module
python mcp_server_example.py
6

Launch Streamlit demos

Several modules include Streamlit-based interactive UIs. Run them to see LangChain and LangGraph agents in action.

streamlit run app.py

MCP Mastery Examples

Client configuration

Example Claude Desktop configuration for connecting to a locally built MCP server from the course materials.

{
  "mcpServers": {
    "mcp-mastery-local": {
      "command": "python",
      "args": ["mcp_server_example.py"],
      "env": {
        "ANTHROPIC_API_KEY": "your_anthropic_api_key"
      }
    }
  }
}

Prompts to try

Learning-oriented prompts and tasks to explore after running the course examples.

- "Build a simple MCP server that exposes a calculator tool using Python FastMCP"
- "Create a LangGraph agent that can search a ChromaDB vector store for relevant documents"
- "Show me how to connect an Ollama local LLM to a LangChain chain"
- "Write a Streamlit UI that lets users chat with a LangGraph agent"
- "Explain how MCP tool schemas differ from LangChain tool definitions"

Troubleshooting MCP Mastery

Import errors for LangChain or LangGraph modules

LangChain has undergone significant package splits. Ensure you install both langchain and langchain-community, and for LangGraph install langgraph separately: pip install langchain langchain-community langgraph langchain-anthropic

Ollama models not responding or connection refused

Make sure Ollama is running locally with ollama serve and that you have pulled the required model, e.g., ollama pull llama3. The default Ollama base URL is http://localhost:11434.

ChromaDB persistence errors on startup

ChromaDB requires a writable directory for its persistence layer. Set the persist_directory parameter in the Chroma client constructor to an absolute path that your user owns, and ensure the directory exists before running.
