Find All Matches

Extracts all pattern matches from text using regex, returning positions and captured groups. Use via MCP in Cursor or Windsurf, or call GET /v1/regex/find-all directly. Perfect for parsing logs, extracting emails, or finding repeated structures. Returns deterministic results with match indices and group captures.

FAQ

How do I find all email addresses in a text block?

Use pattern `[\w.-]+@[\w.-]+\.[a-zA-Z]{2,}` with your text. Returns array of matches with positions and the full email strings.

What's returned when using find-all in MCP tools like Claude Code?

JSON array with each match containing the matched text, start/end positions, and any captured groups from parentheses in your regex.

Can I extract multiple capture groups from each match?

Yes, use parentheses in your pattern. Each match returns an array of captured groups plus the full match text.

Does find-all work with multiline text and complex patterns?

Absolutely. Supports all standard regex flags including multiline, case-insensitive, and global matching across large text blocks.

How is this different from a simple regex search?

Returns ALL matches with precise positioning data, not just the first match. Essential for parsing structured data or counting occurrences.
