MCP with Langchain Sample Setup
Start MCP servers
There are 3 sample MCP servers created in folder mcp_servers, each has 1 or 2 functions. Start and listen for requests on 3 different ports: 8000, 8001, and 8002.
cd mcp_servers
nohup python math_mcp_server.py > math.log 2>&1 &
nohup python weather_mcp_server.py > weather.log 2>&1 &
nohup python which_llm_to_use_mcp_server.py > which_llm.log 2>&1 &
Start MCP client
MCP client works as an interface bridging users and MCP servers.
export OPENAI_API_KEY=sk-svcacct-Tn_rKHd............................your_key_please
streamlit run my_chat_bot_app.py
The streamlit command will start a web UI listening on port 8501. You can play with the bot from there.
