## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Cronly MCP or direct API to monitor cron job failures, check SSL certificate expiry, review server alerts, and inspect crontab backups through natural language.

## Summary

Cronly is an operations monitoring service for cron jobs, SSL certificates, servers, and crontab backups.
It helps teams catch failures and expiry risks early with clear operational alerts.

## Categories

- developer tools & devops

## Toolkit Details

- Tools: 10

## Images

- Logo: https://logos.composio.dev/api/cronly

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for Cronly.
  - Setup:
    - Configure Api Key credentials for Cronly.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

- List failed cron jobs today
- Check SSL certificates expiring soon
- Summarize active Cronly server alerts

## 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. |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK, the OpenAI provider, and the OpenAI SDK
```python
pip install composio composio_openai openai
```

```typescript
npm install @composio/core @composio/openai openai
```

#### Path 1, Step 2: Create a Composio session

Initialize Composio with the OpenAI Responses provider and create a session scoped to Cronly
```python
import json
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
client = OpenAI()

session = composio.create(user_id="your-user-id", toolkits=["cronly"])
tools = session.tools()
```

```typescript
import OpenAI from "openai";
import { Composio } from "@composio/core";
import { OpenAIResponsesProvider } from "@composio/openai";

const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();

const session = await composio.create("your-user-id", { toolkits: ["cronly"] });
const tools = await session.tools();
```

#### Path 1, Step 3: Run Cronly tools with your agent

Send a request, execute the Cronly tool calls through the session, and print the final answer
```python
response = client.responses.create(
    model="gpt-5.6-sol",
    tools=tools,
    input=[{"role": "user", "content": "List Cronly cron jobs that failed in the last 24 hours and summarize the alerts"}],
)

while True:
    tool_calls = [o for o in response.output if o.type == "function_call"]
    if not tool_calls:
        break
    results = composio.provider.handle_tool_calls(response=response, session=session)
    response = client.responses.create(
        model="gpt-5.6-sol",
        tools=tools,
        previous_response_id=response.id,
        input=[
            {"type": "function_call_output", "call_id": call.call_id, "output": json.dumps(results[i])}
            for i, call in enumerate(tool_calls)
        ],
    )

print(response.output_text)
```

```typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "List Cronly cron jobs that failed in the last 24 hours and summarize the alerts" }],
});

while (response.output.some((o) => o.type === "function_call")) {
  const outputs = await composio.provider.handleToolCalls(session, response.output);
  response = await client.responses.create({
    model: "gpt-5.6-sol",
    tools,
    previous_response_id: response.id,
    input: outputs,
  });
}

console.log(response.output_text);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK and your agent framework
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai
```

#### Path 2, Step 2: Create a session with MCP enabled

Create a session scoped to Cronly and read its MCP URL and headers
```python
from composio import Composio

composio = Composio()
session = composio.create(user_id="your-user-id", toolkits=["cronly"], mcp=True)
```

```typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["cronly"],
  mcp: true,
});
```

#### Path 2, Step 3: Connect your agent to the MCP server

Pass the session's MCP URL and headers to your agent and run a Cronly request
```python
import asyncio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions, AssistantMessage, TextBlock

options = ClaudeAgentOptions(
    mcp_servers={
        "composio": {
            "type": "http",
            "url": session.mcp.url,
            "headers": session.mcp.headers,
        }
    },
    system_prompt="You are a helpful assistant with access to Cronly tools.",
    tools=[],
    allowed_tools=["mcp__composio__*"],
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query("List Cronly cron jobs that failed in the last 24 hours and summarize the alerts")
        async for message in client.receive_response():
            if isinstance(message, AssistantMessage):
                for block in message.content:
                    if isinstance(block, TextBlock):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";

const client = await createMCPClient({
  transport: { type: "http", url: mcp.url, headers: mcp.headers },
});

const { text } = await generateText({
  model: openai("gpt-5.6-sol"),
  tools: await client.tools(),
  prompt: "List Cronly cron jobs that failed in the last 24 hours and summarize the alerts",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();
```

## Why Use Composio?

### 1. AI Native Cronly Integration

- Supports both Cronly MCP and direct API based integrations
- Structured, LLM-friendly schemas for reliable cron, SSL, server, and backup monitoring workflows
- Rich coverage for reading, querying, and acting on Cronly operational alert data

### 2. Managed Auth

- Secure API key handling without hard-coding Cronly credentials in your agent code
- Central place to manage, scope, and revoke Cronly access
- Per user and per environment credentials, so staging and production stay cleanly separated

### 3. Agent Optimized Design

- Tools are tuned using real error and success rates to improve reliability over time
- Clear Cronly tool schemas help agents pick the right action for failed jobs, expiring certs, and server alerts
- Comprehensive execution logs so you always know what ran, when, and on whose behalf

### 4. Enterprise Grade Security

- Fine-grained RBAC so you control which agents and users can access Cronly
- Scoped, least privilege access to Cronly monitoring resources
- Full audit trail of agent actions to support incident review and compliance
