Using in Python with mcp streamable_http_client #598

Open

Description

I have the following Python client code, but I keep getting 400 - Client error '400 Bad Request' for url 'https://api.githubcopilot.com/mcp/'

What is the fix for this? (NOTE: I tried many request bodies, none worked. They are commented for reference)

I think the error is happening in this line:
client-native-http.py", line 16, in main | async with streamablehttp_client(

Question:

  1. Is the issue in the step to create streamablehttp_client
  2. Further, what is the right way to call the client - that is, the line result = await session.call_tool ...

Code:

# Based on https://github.com/sooperset/mcp-atlassian?tab=readme-ov-file# Issue: https://github.com/github/github-mcp-server/issues/598import asyncioimport osfrom mcp.client.streamable_http import streamablehttp_clientfrom mcp import ClientSessionasync def main():        # Bearer token from environment variable or configuration    bearer_token=os.getenv("GITHUB_PAT")     # Connect to streamable HTTP server with custom headers    async with streamablehttp_client(        "https://api.githubcopilot.com/mcp/",        headers={            "Authorization": f"Bearer {bearer_token}"        }    ) as (read_stream, write_stream, _):                print("\n\nINFO - Main: In streamablehttp_client part.")        # Create a session using the client streams        async with ClientSession(read_stream, write_stream) as session:            # Initialize the connection            await session.initialize()            print("\n\nINFO - Main: session is: ", session)                        # Get-me             result = await session.call_tool({                "name": "get_me",                "arguments": {"reason": "for information about the user"}            })                        '''            result = await session.call_tool(                "get_me",                {"reason": "for information about the user"}            )            '''                        '''            result = await session.call_tool(                name="get_me",                arguments={"reason": "for information about the user"}            )            '''            '''            result = await session.call_tool(                #"list_branches",                "get_repo",                {"message": "list my git repos"},                #{"owner": "coderdba", "repo": "NOTES"}            )            '''                        print(result)asyncio.run(main())
