WhenLabs When MCP server

WhenLabs When is a small toolkit that plugs six developer checks into your AI assistant. Once it is connected, you can ask your AI to look over your project and it will run the checks for you. It is handy for developers and anyone who keeps a coding project tidy but does not want to run each tool by hand.

What this MCP server does

You ask your AI something like whether your project has any port conflicts. The AI passes that request to this helper, which runs the matching WhenLabs check on your files. The check looks at your project, finds issues, and sends the result back. The AI then explains what it found in plain words. You can also ask for a single summary that rolls up all five scanners at once.

What you can do with it

• Detect your project stack and refresh AI context files
• Check for port conflicts before starting a dev server
• Validate your .env file against a schema
• Spot documentation that has drifted away from the code
• Scan dependency licenses and compare them to a policy
• Time a coding task and record how long it took
• Get one combined report across all five scanners

Try asking your AI

• “Check my project for port conflicts before I start the dev server”
• “Validate my .env file and tell me what is missing”
• “Scan my dependencies for license problems”
• “Give me a full health report on this project”

What it gives back to you

You get answers in the chat, usually as a short list or a summary. For example, a port check may list which ports are already in use, and a license scan may name the packages that break your policy. The .env check tells you which variables are missing or wrong. The timing tools record how long a task took so you can see it later.
