FAQ from Regex Engine MCP - Test, Explain & Build Regex Patterns

Do I need to install anything?

No. This runs on Cloudflare Workers. Add the URL to your AI client’s MCP config and you are ready. No dependencies, no API keys, no setup.

Which regex flavor does it use?

JavaScript regex (ECMAScript). This covers 99% of what web developers and general programmers need, including named capture groups, lookaheads, and all standard flags (g, i, m, s, u).
