## Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Cursor MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

## TL;DR

### Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.

## Connect Cursor to Codex

### How to install Cursor MCP in Codex
### Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.

```bash
codex mcp add composio --url https://connect.composio.dev/mcp
```

## What is the Cursor MCP server, and what's possible with it?

The Cursor MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Cursor account. It provides structured and secure access so your agent can perform Cursor operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CURSOR_GET_AGENT_CONVERSATION` | Get Agent Conversation | Tool to retrieve the conversation history for a specific cloud agent. Use when you need to view the messages exchanged between the user and the agent. Returns error with status 404 if the agent is not found or access is denied. |
| `CURSOR_GET_ME` | Get API Key Info | Tool to retrieve API key information including the key name, creation date, and owner email. Use when you need to verify API key details or validate authentication. |
| `CURSOR_LIST_AGENTS` | List Agents | Tool to retrieve a paginated list of all Cursor Cloud agents. Use when you need to view existing agents, their status, or iterate through agents with pagination. |
| `CURSOR_LIST_MODELS` | List Available Models | Tool to retrieve the list of available AI models in Cursor. Use when you need to discover which models are available for API requests. |
| `CURSOR_LIST_GITHUB_REPOSITORIES` | List GitHub Repositories | Tool to list GitHub repositories accessible to the authenticated user. Use when you need to retrieve all repositories the user has access to through their Cursor account. |

## Supported Triggers

## Creating MCP Server - Stand-alone vs Composio SDK

The Cursor MCP server provides comprehensive access to Cursor operations through Composio. Once connected, you can perform all major Cursor actions directly from Codex using natural language commands.

## Complete Code

None listed.

## Conclusion

### Conclusion
You've successfully integrated Cursor with Codex using Composio's MCP server. Now you can interact with Cursor directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
- Seamless integration across CLI, VS Code, and standalone app
- Natural language commands for Cursor operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Cursor operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Cursor MCP?

With a standalone Cursor MCP server, the agents and LLMs can only access a fixed set of Cursor tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Cursor and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Codex?

Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Cursor tools.

### Can I manage the permissions and scopes for Cursor while using Tool Router?

Yes, absolutely. You can configure which Cursor scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Cursor data and credentials are handled as safely as possible.
