# Problem
OpenAI gpt-4 returned an error when built-in and mcp calls were skipped
due to max_tool_calls parameter. Following is from the server log:
```
RuntimeError: OpenAI response failed: Error code: 400 - {'error': {'message': "An assistant message with
'tool_calls' must be followed by tool messages responding to each 'tool_call_id'. The following tool_call_ids
did not have response messages: call_Yi9V1QNpN73dJCAgP2Arcjej", 'type': 'invalid_request_error', 'param':
'messages', 'code': None}}
```
# What does this PR do?
- Fixes error returned by openai/gpt when calls were skipped due to
max_tool_calls. We now return a tool message that explicitly mentions
that the call is skipped.
- Adds integration tests as a follow-up to
