Original GitHub issue: https://github.com/deepseek-ai/DeepSeek-R1/issues/681

I saw that the deepseek-R1-0528 states that it can support Function Calling. May I ask if it supports MCP protocol? After deploying version 0528 with VLLM, the tool calls did not take effect, and it seems that the chat template did not obtain any tool information.

Afterwards, I replaced the chat template with the template provided by VLLM, but the information related to tool calls in the returned message body always did not appear in the 'tool_calls', but in the 'content'

R1 has poor support for function calling, just like its base model V3
