Check Open Access Status via MCP Server

The `get_article_oa_status` tool checks a DOI and immediately tells you if the article is available in open access. It retrieves not just the status, but also specific locations where you can find the full-text PDF links. This gives your agent precise data points it needs to proceed with literature review tasks. You're not guessing; you know exactly where to look for scholarly material.

Managing Literature Discovery with OpenAI Agents SDK

Your agents can now build sophisticated workflows that start by gathering a list of DOIs, then passing them sequentially through the `get_article_oa_status` tool. This process verifies availability before any deeper analysis begins. The agent handles the handoff: if one paper is open access and another isn't, the workflow adjusts automatically, saving you time on dead-end research paths.

Structured Data Retrieval for Agents

The tool returns structured data containing the OA status and multiple URL options. This means your agent doesn't just get a 'yes/no'; it gets actionable links. Your production agents can use this reliable output to populate databases or trigger subsequent actions, making the entire system dependable.

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(
