🤖 Using with AI Agents

OpenAI Agents Integration

You can load this MCP server in your OpenAI agent workflow using the agents.mcp.MCPServerStdio interface:

from agents.mcp import MCPServerStdio

async with MCPServerStdio(
    name="OpenAlex MCP For Author disambiguation and works",
    cache_tools_list=True,
    params={
        "command": "uvx",
        "args": [
            "--from", "git+https://github.com/drAbreu/[email protected]",
