This guide walks you through connecting lc.cx to the OpenAI Agents SDK using the Composio tool router. By the end, you'll have a working lc.cx agent that can create short links, generate qr codes, track link clicks, and manage your tags through natural language commands. This guide will help you understand how to give your OpenAI Agents SDK agent real control over a lc.cx account through Composio's lc.cx MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved.
lc.cx is a URL shortening service for branded links, workspaces, tags, QR codes, and click stats. Use it to share cleaner links, track performance, and manage branded campaigns from one API.

This guide will help you understand how to give your OpenAI Agents SDK agent real control over a lc.cx account through Composio's lc.cx MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.
The OpenAI Agents SDK is a lightweight framework for building AI agents that can use tools and maintain conversation state. It provides a simple interface for creating agents with hosted MCP tool support.
Key features include:
The lc.cx MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your lc.cx account. It provides structured and secure access to your short links, branded domains, workspaces, tags, and account context, so your agent can create and manage short links, organize them with tags, review available domains and workspaces, and check account quotas on your behalf.
Composio's Composio SDK helps agents find the right tools for a task at runtime. You can plug in multiple toolkits (like Gmail, HubSpot, and GitHub), and the agent will identify the relevant app and action to complete multi-step workflows. This can reduce token usage and improve the reliability of tool calls. Read more here: Getting started with Composio SDK
The tool router generates a secure MCP URL that your agents can access to perform actions.
The Composio SDK follows a three-phase workflow:

OPENAI_API_KEY=sk-...your-api-key
COMPOSIO_API_KEY=your-api-key

import { OpenAIAgentsProvider } from '@composio/openai-agents';
import { Agent, hostedMcpTool, run, OpenAIConversationsSession } from '@openai/agents';
import * as readline from 'readline';Composio and OpenAIAgentsProvider classes are imported to connect your OpenAI agent to Composio tools like lc.cx.dotenv.config();

});Agent instance with a name, model (gpt-5), and clear instructions about its purpose.tools array includes a hostedMcpTool that connects to the MCP server URL we created earlier.headers object includes the Composio API key for secure authentication with the MCP server.requireApproval: 'never' means the agent can execute lc.cx operations without asking for permission each time, making interactions smoother.// Keep conversation state across turns

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.
A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.
We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.
As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.
Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
