## Introduction

Cowork is Anthropic's AI agent for knowledge work. Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks.
This guide walks you through the easiest and most secure way to connect your Cronly account to Cowork via Composio Connect, enabling it to list failed cron jobs today, check SSL certificates expiring soon, summarize active Cronly server alerts, and more such actions on your behalf without compromising your account security.

## Also integrate Cronly with

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

## Connect Cronly to Claude Cowork

### Connecting Cronly to Claude Cowork
1. Open Customize
In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.
2. Add the Composio MCP server
Click Add custom connector and paste in the Composio MCP server URL:

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

## What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.
With Composio Connect, Cowork can securely access apps like Cronly through MCP without you sharing account credentials directly with the agent.

## 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. |

## Supported Triggers

## 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 Claude Cowork?

Yes, you can. Claude Cowork 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.
