Percy MCP Server for OpenAI Agents SDK 10 tools — connect in under 2 minutes

Built by Vinkius GDPR 10 Tools SDK

The OpenAI Agents SDK enables production-grade agent workflows in Python. Connect Percy through Vinkius and your agents gain typed, auto-discovered tools with built-in guardrails. no manual schema definitions required.

Vinkius supports streamable HTTP and SSE.

python
import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerStreamableHttp

async def main():
    # Your Vinkius token. get it at cloud.vinkius.com
    async with MCPServerStreamableHttp(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as mcp_server:

        agent = Agent(
            name="Percy Assistant",
            instructions=(
                "You help users interact with Percy. "
                "You have access to 10 tools."
            ),
            mcp_servers=[mcp_server],
        )

        result = await Runner.run(
            agent, "List all available tools from Percy"
        )
        print(result.final_output)

About Percy MCP Server

Inject precision quality assurance workflows directly bounding LLM models via the Percy Visual Testing API (by BrowserStack). Programmatically verify pixel regressions executing queries evaluating visual boundaries natively across target projects. Inspect deep status arrays parsing CI build limits dynamically, extract metrics evaluating granular snapshot checkpoints asynchronously, and force immediate test baseline approvals seamlessly directly from explicit prompt commands naturally.

The OpenAI Agents SDK auto-discovers all 10 tools from Percy through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries Percy, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

What you can do

  • Project Navigation — Read bounded parameters tracking Percy deployments isolating configurations determining explicitly specific active QA targets natively
  • Automated Build Oversight — Track specific arrays extracting dynamic checks returning pipeline checkpoints (approved/failed/unreviewed limits) explicitly seamlessly
  • Visual Snapshot Operations — Log natively extracting bounds verifying comparison properties logging rendering differences mapping exact explicit width constraints
  • Baseline Affirmations — Mutate bounding loops forcing active execution of JSON logic structurally bypassing native clicks allowing test approvals implicitly (approve_build or approve_snapshot)

The Percy MCP Server exposes 10 tools through the Vinkius. Connect it to OpenAI Agents SDK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use OpenAI Agents SDK with the Percy MCP Server

OpenAI Agents SDK provides unique advantages when paired with Percy through the Model Context Protocol.

01

Native MCP integration via `MCPServerSse`, pass the URL and the SDK auto-discovers all tools with full type safety

02

Built-in guardrails, tracing, and handoff patterns let you build production-grade agents without reinventing safety infrastructure

03

Lightweight and composable: chain multiple agents and MCP servers in a single pipeline with minimal boilerplate

04

First-party OpenAI support ensures optimal compatibility with GPT models for tool calling and structured output

Percy + OpenAI Agents SDK Use Cases

Practical scenarios where OpenAI Agents SDK combined with the Percy MCP Server delivers measurable value.

01

Automated workflows: build agents that query Percy, process the data, and trigger follow-up actions autonomously

02

Multi-agent orchestration: create specialist agents. one queries Percy, another analyzes results, a third generates reports

03

Data enrichment pipelines: stream data through Percy tools and transform it with OpenAI models in a single async loop

04

Customer support bots: agents query Percy to resolve tickets, look up records, and update statuses without human intervention

Percy MCP Tools for OpenAI Agents SDK (10)

These 10 tools become available when you connect Percy to OpenAI Agents SDK via MCP:

01

approve_build

/approve` moving the test suite to green. Approve all unreviewed snapshots in a Percy build. Marks the entire build as visually approved for deployment

02

approve_snapshot

Approve a single Percy snapshot. Marks it as visually correct, updating the baseline for future comparisons

03

get_build_details

Get full details of a Percy build including state, total/unreviewed snapshot counts, approved/rejected snapshots, branch, commit SHA, and finalized timestamp

04

get_project_details

Get full details of a Percy project including name, slug, default branch, auto-approve enabled, browser targets, and build count

05

get_snapshot_details

Get full details of a Percy snapshot including name, review state, widths, fingerprint, and comparison count

06

list_browsers

List all supported browser families on Percy. Returns browser names, versions, and OS combinations for cross-browser visual testing

07

list_builds

List builds for a Percy project. Each build contains snapshots from a test run. Returns build IDs, states (processing/finished/failed), branch names, commit SHAs, and snapshot counts

08

list_comparisons

List visual comparisons for a Percy snapshot. Each comparison shows the diff between baseline and head at a specific width/browser. Returns diff images, diff percentages, and browser info

09

list_projects

List all projects on Percy (BrowserStack). Percy is the leading visual regression testing platform that captures snapshots and detects pixel-level UI differences across builds. Uses JSON:API format. Returns project names, slugs, and browser configs

10

list_snapshots

List snapshots in a Percy build. Each snapshot is a captured page/component at specific widths and browsers. Returns snapshot names, review states (unreviewed/approved/rejected), and diff percentages

Example Prompts for Percy in OpenAI Agents SDK

Ready-to-use prompts you can give your OpenAI Agents SDK agent to start working with Percy immediately.

01

"Log explicitly the builds targeting structural limits seamlessly isolating project 'org-slug/my-app' dynamically checking bounding states natively."

02

"Reverse check explicit structures extracting limits comparing properties cleanly bounding snapshot ID 'snap_778' natively efficiently."

03

"Force explicit validation mutating boundaries executing structurally an approval across build ID '8910' automatically natively flawlessly securely."

Troubleshooting Percy MCP Server with OpenAI Agents SDK

Common issues when connecting Percy to OpenAI Agents SDK through the Vinkius, and how to resolve them.

Percy + OpenAI Agents SDK FAQ

Common questions about integrating Percy MCP Server with OpenAI Agents SDK.

01

How does the OpenAI Agents SDK connect to MCP?

Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
02

Can I use multiple MCP servers in one agent?

Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
03

Does the SDK support streaming responses?

Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
