## Introduction

### How to connect Cronly MCP with ChatGPT Work
[ChatGPT Work](https://openai.com/chatgpt-work/) is an agent inside ChatGPT built for your most ambitious work. It takes action across your apps and files, stays with a project for hours, and turns a goal into finished materials like sheets, slides, and docs - not just answers.
In this guide, I will explain the easiest and most secure way to connect your Cronly account to ChatGPT Work via Composio Connect, so it can list failed cron jobs today, check ssl certificates expiring soon, summarize active cronly server alerts through natural language commands without ever putting your account credentials at risk.

- [Hermes](https://composio.dev/toolkits/cronly/framework/hermes-agent)

## TL;DR

### Why use Composio over default connectors?
- Apps with read and write access. Default connectors mostly can read your data. Composio's Cronly integration lets ChatGPT Work take actions like creating drafts, sending updates, labeling records, and more.
- 1,000+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
- One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
- Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
- Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

## Connect Cronly to ChatGPT Work

### Prerequisites
- A ChatGPT account with access to ChatGPT Work (rolling out across Pro, Enterprise, Edu, Plus, and Business plans). We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), which is available on every plan.
- Access to the Cronly workspace you want to connect.
- [Composio MCP](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt).
Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.
### Step-by-step: Connect Cronly to ChatGPT Work
### 1. Open the MCP settings
In ChatGPT Work, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab.
### 2. Add the server
Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL:

```bash
https://connect.composio.dev/mcp
```

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

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CRONLY_CREATE_CERTIFICATE` | Create Certificate Monitor | Create an SSL/TLS certificate-expiry monitor for a hostname and port. |
| `CRONLY_CREATE_MONITOR` | Create Monitor | Create a cron-job heartbeat monitor and return its ID and sensitive pulse token. |
| `CRONLY_CREATE_PROJECT` | Create Project | Create a project for organizing Cronly monitors and certificate checks. |
| `CRONLY_DELETE_CERTIFICATE` | Delete Certificate Monitor | Permanently delete an SSL/TLS certificate monitor by numeric ID. |
| `CRONLY_DELETE_MONITOR` | Delete Monitor | Permanently delete a cron-job monitor by numeric ID. |
| `CRONLY_DELETE_PROJECT` | Delete Project | Permanently delete a Cronly project by numeric ID. |
| `CRONLY_GET_COMPANY` | Get Company | Return safe organization, timezone, and subscription-summary fields for the connected Cronly account without exposing billing or integration secrets. |
| `CRONLY_GET_RESOURCE` | Get Resource | Get one monitor, project, certificate, user, server, or backup by its resource identity. |
| `CRONLY_LIST_RESOURCES` | List Resources | List notifications, monitors, projects, certificates, users, servers, or backups. Notifications return one page with a continuation cursor; other resource types return their complete arrays. |
| `CRONLY_PULSE_MONITOR` | Pulse Monitor | Record a successful heartbeat for a monitor using its sensitive pulse token. This changes monitor run state even though Cronly exposes it as GET. |

## Frequently Asked Questions

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

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

### Can I use Tool Router MCP with ChatGPT Work?

Yes, you can. ChatGPT Work 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 Cronly tools.

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

Yes, absolutely. You can configure which Cronly 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 Cronly data and credentials are handled as safely as possible.
