[v0.32.0]: MCP Client, Tiny Agents CLI and more!

🤖 Powering LLMs with Tools: MCP Client & Tiny Agents CLI

✨ The huggingface_hub library now includes an MCP Client, designed to empower Large Language Models (LLMs) with the ability to interact with external Tools via Model Context Protocol (MCP). This client extends the InfrenceClient and provides a seamless way to connect LLMs to both local and remote tool servers!

pip install -U huggingface_hub[mcp]

In the following example, we use the Qwen/Qwen2.5-72B-Instruct model via the Nebius inference provider. We then add a remote MCP server, in this case, an SSE server which makes the Flux image generation tool available to the LLM:

import os
from huggingface_hub import ChatCompletionInputMessage, ChatCompletionStreamOutput, MCPClient
async def main():
async with MCPClient(
provider="nebius",
model="Qwen/Qwen2.5-72B-Instruct",
api_key=os.environ["HF_TOKEN"],
) as client:
await client.add_mcp_server(type="sse", url="https://evalstate-flux1-schnell.hf.space/gradio_api/mcp/sse")
messages = [
{
"role": "user",
"content": "Generate a picture of a cat on the moon",
}
]
async for chunk in client.process_single_turn_with_tools(messages):
# Log messages
if isinstance(chunk, ChatCompletionStreamOutput):
delta = chunk.choices[0].delta
</tr></table>
