MCP support
The hosted MCP server exposes tools to list, inspect, create, update, organize, activate, and delete cronjobs. It connects to the user's cronjob.de account using OAuth 2.1 with PKCE.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

What the service does
cronjob.de calls a URL you provide on a schedule you set, from once a year to every minute. The script behind that URL runs on your own server — cronjob.de never executes code of yours. It records the response, keeps a call log and emails you when a call fails. It exists for websites on shared hosting with no cron of their own, or with intervals that are too coarse.
Tools
| Tool | Does | Annotation |
|---|---|---|
list_jobs | List your cronjobs | readOnlyHint |
get_job | Show one cronjob in full | readOnlyHint |
list_job_history | Read the call log | readOnlyHint |
list_folders | List folders | readOnlyHint |
create_job | Create a cronjob | write |
update_job | Change a cronjob | write |
set_job_active | Enable or disable | write |
move_job | Move to another folder | write |
create_folder | Create a folder | write |
delete_job | Delete a cronjob | destructiveHint |
Every tool carries a title and the applicable readOnlyHint or
destructiveHint, so your client can answer read-only questions without
prompting and check before deleting. delete_job additionally requires naming
the job, so deletion cannot happen by accident.
Schedules can be given in plain language — "every second Tuesday at 6:45" — crontab syntax is optional.
Security
- OAuth 2.1 with PKCE. You approve access in your browser, in your own session; no password ever reaches the assistant.
- Access tokens last one hour. Refresh tokens last 30 days and rotate on every use; reusing one revokes the entire chain.
- Only hashes are stored. Reading the database would not let anyone sign in.
- Every call is written to an audit log in your account, so you can see what the assistant did and revoke access at any time.
Privacy Policy
https://www.cronjob.de/datenschutz
All processing takes place in the EU, on servers in Nuremberg, Falkenstein and Helsinki. The contracting party is a German company. A data processing agreement under Article 28 GDPR is available for cronjobs that handle personal data.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
