How to Use the Mockaroo MCP in OpenAI Agents SDK

Q: How do I connect the Mockaroo MCP Server to the OpenAI Agents SDK?

Install the package, then initialize MCPServerStreamableHttp with your Vinkius endpoint URL. Pass this server instance in the mcpservers list when creating your Agent constructor.

Q: Can my OpenAI Agents SDK system discover Mockaroo field types dynamically?

Yes, your agent automatically calls listfieldtypes to see what formats are supported. It then uses that list to construct payload schemas without hardcoded values.

Q: How does the OpenAI Agents SDK handle rate limits when calling Mockaroo?

You should set cacheToolsList=True in your configuration to limit discovery requests. This keeps your agent from constantly hitting the endpoint just to find available tools.

Schema-Driven Generation in OpenAI Agents SDK

Your agents call `generate_from_schema` to instantly build realistic datasets using your saved templates. This bypasses manual configuration by pulling configured layouts directly from your account. This integration runs inside an async context manager using `MCPServerStreamableHttp`. Because the setup validates actions before execution, your pipeline won't trigger broken schema calls.

Dynamic Field Mapping on the Fly

When your agent needs to build a custom dataset without a pre-saved template, it queries `list_field_types` to inspect valid options. A quick call to `generate_mock_data` then populates the exact fields your test suite requires. By discovering tools via the HTTP stream, the agent maps formats and spits out clean JSON over the MCP connection. This prevents silent failures in your production pipelines.

Audit Mock Inventories Safely

Calling `list_datasets` and `list_schemas` lets your agent inspect your existing assets before spinning up new generation tasks. Redundant files disappear because your workspace remains organized. By evaluating the returned lists, the agent decides whether to write new mock files or reuse old ones. You monitor these discovery calls directly inside your OpenAI dashboard.

Setup guide

Set up Mockaroo 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 Mockaroo tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
