Overview

AI-generated overview

A local MCP server for parsing, validating and explaining cron expressions, and for generating schedules.

What you can do
Parse cron expressions into their component fields and meanings, with human-readable explanations of when a schedule fires, plus validation of expressions and help generating schedules.
When to use it
Useful when writing or reviewing cron jobs, checking whether an expression means what you intended, or turning a plain-language schedule into a cron expression.
Requirements
Runs as a local stdio process, started with npx from the npm package cron-forge-mcp; needs Node.js and network access to fetch the package. No accounts, API keys or environment variables are declared.
Before you install
The README describes a large multi-server collection, so confirm you are installing the cron package specifically. The server only parses and validates expressions; it does not install or run the jobs, so verify schedules in the target system.

Installation

In SourceWeft

  1. Open Cron in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
