Overview

AI-generated overview

Lets an assistant parse, validate, and explain cron expressions and compute their next scheduled run times.

What you can do
Exposes three tools: explain_cron turns a cron expression into human-readable English, validate_cron checks syntax and returns a detailed field-by-field analysis, and next_cron_runs calculates the next N run times for an expression. It is a small, focused utility for working with cron schedules without leaving the editor or chat.
When to use it
Useful when writing or reviewing cron schedules and you want a plain-language explanation, a syntax check, or a preview of upcoming run times. Worth adding if you regularly edit crontabs, CI schedules, or job configs and want quick verification.
Requirements
Runs locally as a stdio process, typically launched with npx cron-forge-mcp; Node.js and npm are needed. No accounts, API keys, environment variables, or headers are declared. Desktop-only; not available as a web executable.
Before you install
The tools only parse, explain, and compute schedules; they do not install or modify crontabs. The README's build-from-source section clones a public repository and runs npm install and npm start, which executes third-party code on your machine. No credentials are requested.

Installation

In SourceWeft

  1. Open Cron Forge Mcp 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.
