This MCP server provides a powerful interface for precise text manipulation and pattern matching. By using tools like execute_regex and extract_substring_indices, AI agents can perform complex string operations such as identifying capture groups, finding exact character offsets, and detecting specific patterns within large datasets. It is particularly useful for parsing structured logs, extracting metadata from unstructured text, or validating route patterns with match_route. The server also includes specialized logic to detect 'islands' of content using the detect_islands tool, making it an essential bridge for any agent requiring deterministic regex-based data extraction.

See how to talk to your AI agent using Regex Execution and Group Extractor.

Use `execute_regex` to find all email addresses in this text: 'Contact us at support@vinkius.com or admin@example.org'.

[{"match": "support@vinkius.com", "start": 24, "end": 43}, {"match": "admin@example.org", "start": 47, "end": 65}]

Extract the indices of the word 'hello' in 'hello world, hello again'.

[{"start": 0, "end": 5}, {"start": 13, "end": 18}]

Check if the path '/api/users/123' matches the pattern '/api/:id'.

{"params": {"id": "users/123"}}

You can run any valid regular expression against a target string to retrieve an array of matches, including capture groups and their exact start and end character positions.
