Based on Building a Basic MCP Server with Python by Alex Merced

Testing it in vscode

Requirements

• VSCode Version =>1.99.0

Instructions

1. Open the environment in the devcontainer (vscode command palette > Dev Containers: Reopen in Container)
2. Run task mix-server:run
3. Open the command palette and select MCP: List Servers
4. Choose mix_server
5. Start it
6. Set Copilot to Agent mode by choosing "Agent" in the dropdown option next to the prompt textbox.
7. Ask Github copilot something like "Summarize the CSV file named sample.csv." or "How many rows are in sample.parquet?" Copilot will detect the appropriate tool, call the MCP server, and respond with the results—powered by the Python code.
