mcp-samples

The client will:

1. Connect to the math server via stdio
2. Initialize a session
3. Load MCP tools
4. Create a ReAct agent using GPT-4
5. Process mathematical queries like "what's (3 + 5) x 12?"

Note

There appears to be a typo in the model name in client.py. It should be "gpt-4" instead of "gpt-4o".

Run

make run
