How to Use the Assertible MCP in OpenAI Agents SDK

Q: How do I trigger Assertible tests from the OpenAI Agents SDK?

Run runservicetests inside your agent workflow. Pass the service ID to execute all configured API assertions immediately.

Q: Does the OpenAI Agents SDK support automatic spec updates in Assertible?

Yes. The agent uses syncspecification to upload your Swagger or OpenAPI definitions. This keeps your test assertions aligned with your code changes.

Q: Can I display Assertible status badges using the OpenAI Agents SDK?

Fetch badge URLs with getservicestatusbadge or getteststatusbadge. This MCP server returns markdown format to update your pull request comments.

Q: How do I run a single test instead of the whole suite?

Use runspecifictest to target one critical path. This keeps execution times low during quick validation steps.

Run your Assertible API test suites automatically inside OpenAI Agents SDK workflows.

Trigger and Track Deployments

`create_deployment` kicks off your API test suites the second code hits your servers. Your agent monitors the run and stops the pipeline if a test fails. You do not need to check the Assertible dashboard. The OpenAI Agents SDK reads the deployment status directly to route execution to the next specialized node.

Sync Specs via Assertible MCP Server

`sync_specification` keeps your Assertible tests updated by pushing OpenAPI files straight from your OpenAI Agents SDK runtime. This prevents your test suites from drifting when developers modify routes. The agent handles the upload using your ASSERTIBLE_SYNC_TOKEN. This keeps your OpenAI Agents SDK assertions matching your current codebase.

Validate Payloads with JSON Schema

`validate_json` checks your API responses against Draft 4 JSON schemas inside your OpenAI Agents SDK workflow. The tool runs locally without authentication, making it fast and secure. This MCP tool checks structures before they hit your production database. You get immediate, structured feedback to guide the OpenAI Agents SDK's next step.

Setup guide

Set up Assertible 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 Assertible tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
