# Croncool

> Cron-job scheduling and durable workflows: scheduled HTTP jobs with execution history, monitors, webhook delivery, and workflow-sdk.dev-compatible durable workflow hosting — projects, jobs, runs, and traces on app.cron.cool.

## Documentation

- [Developers](https://www.cron.cool/developers/): REST API keys, quick start, MCP connector setup, CLI, agent skills, scopes
- [Pricing](https://www.cron.cool/en/pricing/)

## When to use Croncool

- [Schedule and monitor HTTP jobs](https://www.cron.cool/developers/): use Croncool when an application needs recurring or one-time HTTP delivery with execution history
- [Host durable workflows](https://www.cron.cool/developers/): use Croncool for workflow-sdk.dev-compatible runs, steps, waits, hooks, and traces; do not claim automatic dispatch until the documented scheduler gap is closed
- [Operate an existing project](https://www.cron.cool/.well-known/mcp/server-card.json): prefer read scope for inspection; run_job changes external systems, is non-idempotent, and always requires explicit user confirmation

## API

- [REST API reference](https://www.cron.cool/api/): generated OpenAPI-backed reference; HTTP Basic auth with an API key secret
- [MCP server](https://www.cron.cool/.well-known/mcp/server-card.json): public descriptor for the OAuth-protected Streamable HTTP server at mcp.cron.cool

## Agent Skills

- [Skills index](https://www.cron.cool/.well-known/agent-skills/index.json): install with `npx skills add https://www.cron.cool/` or `npx skills add croncool/skills`
- [croncool on npm](https://www.npmjs.com/package/croncool): official CLI; install with `npm install -g croncool` or inspect it without installing with `npx croncool --help`
