Still facing the error code: 400 in both L3 and L5

hi @agparth

are running codes locally?

lesly suggested this possible solution

MCP:L5 fixes in mcp_chatbot.py to run it locally

Interesting! I see, the L5/mcp_project/mcp_chatbot.py and it looks like the problem is in the tool_use handling block. Try using this instead… async def process_query(self, query): messages = [{‘role’: ‘user’, ‘content’: query}] response = self.anthropic.messages.create( max_tokens=2024, model = ‘claude-sonnet-4-6’, tools=self.available_tools, messages=messages ) pr…

hope it helps
