This MCP server provides a structured way to understand regular expressions. Using parse_regex, you can transform any pattern into an Abstract Syntax Tree (AST). The explain_token tool breaks down individual nodes like quantifiers and lookarounds, while audit_regex identifies critical risks such as catastrophic backtracking or missing anchors.

Explain what `^([a-z]+)$` does.

This regex matches a string consisting only of lowercase letters from start to end.

Is `(a+)+` dangerous?

Yes, this pattern contains nested quantifiers that pose a high risk of catastrophic backtracking.

Parse the regex `\d{3}-\d{2}`.

The pattern consists of three digits, followed by a hyphen, and then two digits.

Use the `audit_regex` tool to scan for backtracking risks and syntax errors.
