Perplexity

Audit orders during multi-agent handoffs

This integration exposes `list_orders` and `get_order` directly to your multi-agent architecture. When a specialized support agent hands off a customer billing dispute, the receiving agent instantly pulls the exact transaction record to verify the purchase. Your OpenAI dashboard logs every single tool call during this handoff. You get full execution traces, which means you can audit exactly why an agent decided to confirm or flag a specific order.

Validate active subscriptions before running tasks

The MCP Server lets your agent query `get_subscription` and `list_subscriptions` to check customer status on the fly. Built-in guardrails in the OpenAI Agents SDK intercept these calls, preventing the agent from performing downstream actions if a subscription is expired or unpaid. Setting this up takes zero configuration beyond connecting the endpoint. Your agent auto-discovers the tools and can immediately run checks against your live store data.

Sync store settings and product variants

Your agent uses `list_stores` and `list_variants` to match incoming requests with your actual catalog. It queries the active store layout to make sure it only references valid SKUs and active pricing structures during conversations. Caching the tool list ensures your agent responds in milliseconds. By keeping these lookups fast, you avoid unnecessary roundtrips to the external billing API.

Setup guide

Set up Lemon Squeezy 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 Lemon Squeezy tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Lemon Squeezy MCP in OpenAI Agents SDK

Install the package using pip and initialize the connection with the HTTP server streamable class. Pass the resulting server instance into your Agent constructor's server list. The tools are auto-discovered immediately.

Yes. You can write custom interceptors that inspect the arguments passed to tools like `list_orders` or `get_subscription` before execution. This ensures the agent never pulls data it shouldn't access.

Yes, every transaction query is fully visible in your developer dashboard. When an agent runs `list_customers`, you see the raw input parameters and the JSON response in the trace log.

Use the cache tools parameter to keep schema lookups local. For heavy tasks involving `list_orders`, write your agent prompt to fetch data in small batches rather than requesting everything at once.

This MCP Server processes customer emails and subscription status inside an isolated V8 sandbox. No personal data is stored on Vinkius servers, keeping your customer records secure.
