How to Use the DummyJSON MCP in OpenAI Agents SDK

Q: How do I connect the DummyJSON MCP Server to my OpenAI Agents SDK pipeline?

Install openai-agents first. You then initialize MCPServerStreamableHttp pointing to the Vinkius endpoint, set cacheToolsList=True for speed, and pass it to your Agent constructor.

Perplexity

Fast e-commerce testing with OpenAI Agents SDK

This MCP Server exposes `add_cart` and `get_user_carts` to let your OpenAI Agents SDK agent simulate checkout flows. The SDK automatically registers these DummyJSON endpoints as tools. If your OpenAI Agents SDK agent decides a user needs to modify their order, it triggers the DummyJSON `update_cart` tool natively without manual schema writing. You can watch the entire cart lifecycle execute in real-time inside your OpenAI Agents SDK trace logs for DummyJSON.

Secure user authentication flows

This MCP Server provides `auth_login` and `auth_refresh_token` to handle mock login loops in your OpenAI Agents SDK pipelines. Testing login loops in production requires real-looking tokens that match DummyJSON schemas inside your OpenAI Agents SDK environment. OpenAI's tracing dashboard tracks these DummyJSON calls step-by-step to monitor agent behavior. You see exactly when the OpenAI Agents SDK agent checks the profile via the DummyJSON `auth_get_me` tool to verify permissions.

Native OpenAI Agents SDK mock data search

This MCP Server delivers `search_products` and `add_comment` to query mock posts and products inside your OpenAI Agents SDK agent. By running this OpenAI Agents SDK setup, you bypass the need for spin-up databases when fetching DummyJSON records. Your OpenAI Agents SDK agent gets immediate access to DummyJSON tools like `list_posts` and `get_recipes_by_tag` to fill context windows. You don't have to write custom mock endpoints for DummyJSON inside your OpenAI Agents SDK codebase.

Setup guide

Set up DummyJSON 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 DummyJSON tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate DummyJSON 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="DummyJSON Agent",
            instructions="You have access to DummyJSON tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about DummyJSON MCP in OpenAI Agents SDK

Install `openai-agents` first. You then initialize `MCPServerStreamableHttp` pointing to the Vinkius endpoint, set `cacheToolsList=True` for speed, and pass it to your Agent constructor.

Yes, the SDK auto-discovers every tool exposed by the server. Your agent instantly gains access to endpoints like `list_products` and `add_todo` without manual registration.

The SDK reads the JSON schema exposed by this MCP Server at runtime. It forces the agent to match the exact arguments required by tools like `update_product` or `delete_user`.

You can manage tool visibility directly in your agent configuration. If you only want to test social features, pass a filtered list of tools like `add_post` and `get_post_comments` to the agent.

Vinkius runs the server in an isolated sandbox, meaning your mock JWTs from `auth_login` and test payloads are ephemeral. No personal developer data or API keys are ever stored on disk.
