[BUG] openai_client.py example fails with 400 Bad Request

[hutho]

Hello,

I am having trouble running the openai_client.py example on a fresh installation. I have followed the Quick
Start guide, and the coderunner container appears to be running correctly. I can access the MCP server via its
IP address in a browser (which returns the expected "Not Acceptable" error), but the Python client fails.

Steps to Reproduce:

1. Cloned the repository.
2. Ran sudo ./install.sh successfully.
3. Created a venv and ran pip install -r examples/requirements.txt.
4. Confirmed the coderunner container is running via container list.
5. Added 192.168.64.2 coderunner.local to my /etc/hosts file.
6. Exported my OPENAI_API_KEY.
7. Ran the client using the venv's python: ./coderunner/venv/bin/python3
   coderunner/examples/openai_agents/openai_client.py

Expected Behavior:

The script should start and prompt for input.

Actual Behavior:

The script fails immediately with a 400 Bad Request error.

Terminal Output:

1 > httpx.HTTPStatusError: Client error '400 Bad Request' for url 'http://192.168.64.2:8222/mcp'
2 > 3 > 4 > **`container logs coderunner` shows:** 5 > 6 > 1 > WARNING: Invalid HTTP request received. 2 >

current version of the coderunner server. Any help would be greatly appreciated.
