How to Use the PagePixels MCP in OpenAI Agents SDK

Q: How do I manage rendering configurations inside OpenAI Agents SDK?

You use createscreenshotconfig to store viewport dimensions and target selectors. Your agent then queries these configurations using listscreenshotconfigs to run targeted visual checks.

Q: What happens to the URLs and HTML data sent from OpenAI Agents SDK to PagePixels?

All HTML payloads and target URLs processed by snapcustomhtml are sent over encrypted HTTPS and processed in ephemeral sandboxes. PagePixels generates the screenshot, returns the image, and discards the raw source code immediately to prevent data leaks.

Your OpenAI Agents SDK pipelines can now capture, track, and analyze web layouts using real-time screenshots.

Automated Visual Testing for OpenAI Agents SDK

The `quick_snap` tool lets your OpenAI Agents SDK instances capture raw web layouts directly inside your autonomous workflows. You pass a URL, and the agent gets a rendered image back without needing to spin up local browser instances or manage complex driver configurations. OpenAI's built-in guardrails validate these incoming image payloads before they hit your agent's vision processing step. Because the agent manages this via an external MCP Server, you avoid running heavy headless engines inside your serverless runtime environment.

Persistent Screenshot Configurations

The `create_screenshot_config` tool establishes reusable rendering profiles that your OpenAI Agents SDK can trigger on a schedule. This saves you from sending massive payload parameters on every single run, keeping your agent's token usage down. When your automated agent detects a layout change, it updates existing profiles using `update_screenshot_config` to adapt viewport sizes dynamically. You track these changes across test runs using the OpenAI dashboard tracing tools to pinpoint exactly where a visual regression occurred.

Rendering Custom HTML in Production Pipelines

The `snap_custom_html` tool converts raw code blocks into high-resolution images instantly inside your OpenAI Agents SDK setup. This allows your agent to generate visual reports, render dynamic charts, or test UI components on the fly. By offloading the rendering engine to Vinkius, your production agent avoids cold-start latency issues associated with local browser environments. If a layout fails to render, the agent pulls the current configuration state from the MCP Server with `get_screenshot_config` to diagnose the error.

Setup guide

Set up PagePixels 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 PagePixels tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about PagePixels MCP in OpenAI Agents SDK

Setup requires running pip install openai-agents and configuring MCPServerStreamableHttp with your endpoint. Your agent automatically registers PagePixels MCP Server tools like `quick_snap` without manual schema definitions.

Yes. The PagePixels MCP Server handles concurrent capture requests, allowing multiple specialized agents to call `quick_snap_with_options` simultaneously without blocking your main pipeline.

You use `create_screenshot_config` to store viewport dimensions and target selectors. Your agent then queries these configurations using `list_screenshot_configs` to run targeted visual checks.

You control tool access by filtering the exposed schemas during the agent initialization step. This prevents autonomous agents from accidentally calling destructive tools like `delete_screenshot_config`.

All HTML payloads and target URLs processed by `snap_custom_html` are sent over encrypted HTTPS and processed in ephemeral sandboxes. PagePixels generates the screenshot, returns the image, and discards the raw source code immediately to prevent data leaks.
