Api Key

Cronfree Time Scheduler is an API-based scheduler for recurring webhook calls. Use it to create and remove timezone-aware schedules without running cron.

2 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Cronfree Time Scheduler account to Claude via Composio Connect, enabling it to create weekday webhook for daily reports, remove outdated billing reminder schedule, schedule timezone-aware monthly cleanup webhook, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Cronfree Time Scheduler account

Back in Claude, ask it to connect to Cronfree Time Scheduler or give it any Cronfree Time Scheduler-related task.

For example, ask Claude to:

  • "Create weekday webhook for daily reports"
  • "Remove outdated billing reminder schedule"
  • "Schedule timezone-aware monthly cleanup webhook"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Cronfree Time Scheduler account is ready to use.

What is the Cronfree Time Scheduler Claude Connector, and what's possible with it?

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

Troubleshooting

1. Why does Claude not use the Composio connector for Cronfree Time Scheduler?

The connector can show as connected, but Claude must use it in each Cronfree Time Scheduler conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Cronfree Time Scheduler again.

2. Why does Claude show an MCP server error before Cronfree Time Scheduler connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Cronfree Time Scheduler.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Cronfree Time Scheduler.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Cronfree Time Scheduler authorization link not work?

The Composio connector is one server. Your Cronfree Time Scheduler account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Cronfree Time Scheduler connection.
  • Composio creates a fresh Cronfree Time Scheduler authorization link.
  • Open that link in your browser and finish the Cronfree Time Scheduler sign-in.

4. Why do Cronfree Time Scheduler actions fail after they worked before?

The Cronfree Time Scheduler connection can expire or lose permission.

  • Ask Claude to inspect the Cronfree Time Scheduler connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Cronfree Time Scheduler account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Cronfree Time Scheduler.
  • If the action still fails with a permission error, check that the connected account has that permission in Cronfree Time Scheduler itself.

5. How do I switch to a different Cronfree Time Scheduler account?

Claude can manage the Cronfree Time Scheduler connection for you.

  • Ask Claude to disconnect or delete the current Cronfree Time Scheduler account.
  • Ask Claude to connect Cronfree Time Scheduler again.
  • Open the new Composio authorization link for Cronfree Time Scheduler.
  • Sign in with the other Cronfree Time Scheduler account in the browser.
  • After the account connects, ask Claude to retry the Cronfree Time Scheduler task.

6. Why is my Cronfree Time Scheduler connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Cronfree Time Scheduler connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Cronfree Time Scheduler tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Cronfree Time Scheduler.

FAQ

Frequently asked questions

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

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 Cronfree Time Scheduler tools.

Yes, absolutely. You can configure which Cronfree Time Scheduler 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.

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 Cronfree Time Scheduler data and credentials are handled as safely as possible.
