Look up MDN web docs and browser compatibility with AI

Answers web platform questions from current MDN documentation and browser compatibility data, reporting sources and what it could not confirm.

Use it when

  • You need to know what a web API, CSS property or HTML element does
  • You want to check whether a feature is supported in a given browser
  • You are unsure of an exact feature name and need to search MDN

Tools it uses

  • get-doc
  • search
  • get-compat
Example

Does the dialog element support the closedby attribute in Safari?

I checked the MDN page for the dialog element and its compatibility record. The closedby attribute is listed with partial support in Safari, so I would not rely on it without a fallback. Sources: the dialog element page and its compatibility data. Not established: the exact Safari version where support began, since the compatibility record I read did not give it.

How MDN skills work

  1. Connect MDN

    The MDN MCP server gives the agent its tools.

  2. Ask in plain words

    “Does the dialog element support the closedby attribute in Safari?” Each SKILL.md says when it applies, so only the one that fits is loaded.

  3. Approve any change

    The agent calls the tools in order, checks its work, and shows you any change before it makes it.

How to install MDN skills

In RevampKey the skills install themselves when you connect MDN. In other tools each skill is one folder with a SKILL.md file, and you also need the MDN MCP server connected there.

MDN skills FAQ

What is a MDN agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each MDN skill describes one job, which MDN tools to use in which order, what to check first and when to stop and ask you.

Do the MDN skills change anything on their own?

1 of the 1 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in MDN.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect MDN; elsewhere you copy the folders into your project or skills directory.

Do I need the MDN MCP server too?

Yes. The skills tell the agent how to do the work; the MDN MCP server gives it the tools to do it. The MDN MCP setup guide covers every client.
