How to Use the Hugging Face LLM MCP in OpenAI Agents SDK

Q: How do I connect Hugging Face LLM to OpenAI Agents SDK?

Install the package using pip install openai-agents and set up the server stream. Define your server using MCPServerStreamableHttp pointing to the Vinkius endpoint, then pass it to your Agent constructor in the mcpservers list. Set cacheToolsList=True to keep tool discovery fast and avoid extra network roundtrips.

Q: Can I use Hugging Face LLM models for translation in OpenAI Agents SDK?

Yes, your OpenAI agents can call the translatetext tool directly to offload translation tasks from OpenAI models. This keeps your main agent focused on decision-making while open-source translation models handle the language conversion. The OpenAI SDK handles the tool schema validation automatically.

Q: How does Hugging Face LLM handle question answering inside OpenAI Agents SDK?

The agent invokes the answerquestion tool, passing a context block and a specific query. The Hugging Face LLM extracts the precise answer from the text and returns it to the OpenAI agent. This is ideal for building RAG pipelines where you want to keep extraction costs low.

Q: What open-source models are available for text generation?

You can target models like Mistral or Zephyr through the textgeneration tool. The MCP server routes these requests to Hugging Face's inference endpoints. Your OpenAI agent gets the generated completion back as a standard tool response, letting you mix open-source and proprietary models in one run.

Q: Is my text data secure when using this MCP server?

All raw text, contexts, and queries sent to tools like classifytext or summarizetext are processed securely. Vinkius runs the Hugging Face LLM MCP server in an isolated, ephemeral V8 sandbox. Your prompts and texts are never stored or used to train models, keeping your customer data private.

Run open-source LLMs through your OpenAI Agents SDK workflows with strict safety guardrails and full tracing.

Run open-source LLMs in OpenAI Agents SDK

Stop paying premium rates for basic text tasks. This MCP server lets your OpenAI Agents SDK systems offload work to open-source models on Hugging Face. When your agent needs a quick completion, it calls `text_generation` to hit Zephyr or Mistral. It saves your main OpenAI API budget for complex reasoning while keeping execution fast. Your agent discovers tools like `fill_mask` instantly during startup. You get the speed of open-source models combined with the native tracing tools on your OpenAI developer dashboard. The integration runs through standard HTTP streams without extra configuration.

Guardrailed extraction and classification

OpenAI agents excel at coordinating tasks, but raw extraction is cheaper on specialized open-source models. By exposing `extract_entities` to your agent, you can pull names, locations, and organizations without burning GPT-4 tokens. The OpenAI Agents SDK validates the tool payload before executing, keeping your data structures clean. If the agent needs to sort incoming user messages, it calls `classify_text` to run zero-shot categorization. Your agent system routes the message based on the output, using specialized open-source classifiers instead of expensive general-purpose LLM prompts.

Fast translation and sentiment routing

Build multi-agent handoffs that process incoming international customer feedback. One agent uses `translate_text` to convert the customer's message into English. If the translation requires a tone check, the next agent in your OpenAI Agents SDK pipeline triggers `sentiment_analysis` to check if the user is angry. For long support tickets, the agent runs `summarize_text` before passing the condensed brief to a human operator. You configure this by passing the MCP server list directly to the Agent constructor, letting the SDK handle the underlying HTTP connection pool.

Setup guide

Set up Hugging Face LLM MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Hugging Face LLM tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Hugging Face LLM tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Hugging Face LLM tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Hugging Face LLM Agent",
            instructions="You have access to Hugging Face LLM tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())
