if __name__ == "__main__":
    mcp.run(transport="stdio")

we have three queries as follows-
I have implemented a context loader & a completion endpoint as above I'm using mcp tools & it's completion endpoint with GitHub copilot in VS code.

Hear are my queries-

1. How can I get my recommendation using completion endpoint in completion1.
2. Where I will be getting the recommendation in VS code file editor or in GitHub copilot while MCP is connected & is running.
3. What are the additional implementations I can add here to make the MCP'c workflow better.
   My mcp for now is loading the context & further generation are happening through it one I have sent a query from GitHub copilot.

Please help with the queries I have written above.

I too have faced the same issues when I was working with the MCPs implementation for my environment. I struggled finding a proper implementation of MCP completion with GitHub copilot in VS Code.
