# Crontap

> Crontap is a hosted scheduler for developers and operators: it runs recurring HTTP requests to any API, webhook, or cloud function you control. Describe schedules in plain English or standard cron, attach headers and JSON bodies, set per-schedule timezones, and get alerts when a run fails, times out, or returns an error.

Crontap is part of the [Apihustle](https://apihustle.com/) suite. The web app is used to create and manage schedules; most programmatic access uses the public REST API at `https://api.crontap.com/` with `ApiKey` and `ClientId` request headers (credentials come from the logged-in account).

- Automatic retries with exponential backoff on failed runs; Pro, Ultra, and legacy Pro can tune the per-schedule policy.

## API & developer reference

- [Crontap public API (OpenAPI / Swagger UI)](https://api.crontap.com/docs/): Interactive reference—base URL `api.crontap.com`, auth via `ApiKey` and `ClientId` headers.
- Agent-critical API routes: `GET /v1/account` for caps and usage; `POST /v1/schedule/preview` for plain-English cron previews; explicit schedule pause/resume routes; cursor-paginated schedule history; heartbeat pings and monitor probes.
- Resource management routes: schedules, heartbeats, and uptime monitors are available over authenticated `GET`, `POST`, `PUT`, and `DELETE` endpoints under `/v1`.
- [API documentation portal](https://docs.crontap.com/): Product-linked docs URL (content may be hosted on a third-party doc platform; prefer the Swagger UI above for the live HTTP contract).
- [Crontap on GitHub](https://github.com/crontap/crontap): Source and issue reporting for the product.

## MCP for AI agents

Crontap's production remote MCP server is `https://mcp.crontap.com/mcp`. It lets supported AI clients create and inspect HTTP schedules, uptime monitors, and heartbeats. The client initiates tool calls; Crontap MCP does not wake an agent or schedule a recurring chat prompt.

- [Crontap MCP landing page and guide hub](https://crontap.com/mcp)
<!-- MCP_CLIENT_SETUP_AUTOGEN_BEGIN -->
- Cursor: add `{"mcpServers":{"crontap":{"url":"https://mcp.crontap.com/mcp"}}}` to `~/.cursor/mcp.json`.
- Claude: Open Customize, then Connectors. Choose "+", then Add custom connector. Enter https://mcp.crontap.com/mcp as the remote MCP server URL.
- Claude Code: run `claude mcp add --transport http crontap https://mcp.crontap.com/mcp`.
- ChatGPT: Open Settings, then Security and login, and enable Developer mode. Open ChatGPT Plugins, then choose the plus button to create an app. Enter https://mcp.crontap.com/mcp as the MCP Server URL.
- Codex CLI: run `codex mcp add crontap --url https://mcp.crontap.com/mcp`, then `codex mcp login crontap`.
- VS Code: add `{"servers":{"crontap":{"type":"http","url":"https://mcp.crontap.com/mcp"}}}` to `.vscode/mcp.json`.
- Devin Local: run `devin mcp add crontap https://mcp.crontap.com/mcp`, then `devin mcp login crontap`.
- Gemini CLI: run `gemini mcp add --transport http crontap https://mcp.crontap.com/mcp`.
<!-- MCP_CLIENT_SETUP_AUTOGEN_END -->

Other compatible clients can use their documented remote Streamable HTTP MCP
setup with `https://mcp.crontap.com/mcp`, then complete OAuth. This is generic
compatibility guidance, not a verified client entry.
