The Regex Tester Explainer MCP connects your AI agent to a powerful diagnostic engine. Use execute_regex_test to verify matches and capture groups, check_syntax_validity to ensure compatibility with PCRE, ECMAScript, or POSIX, detect_complexity_risk to identify catastrophic backtracking, and deconstruct_pattern_logic to receive a plain-English breakdown of any pattern.

check_syntax_validity

Validates the syntax of a regex pattern

deconstruct_pattern_logic

Decomposes a regex pattern into its constituent tokens

detect_complexity_risk

Analyzes a regex pattern for catastrophic backtracking risks

execute_regex_test

Tests a regex pattern against multiple sample strings

Does the regex `^\d+$` match the string '12345' in ECMAScript flavor?

Yes, the pattern `^\d+$` matches '12345' because it consists entirely of digits from start to end.

Check if this regex is valid for PCRE: `(?<name>\w+)`

The syntax for `(?<name>\w+)` is valid in the PCRE flavor.

Explain what this regex does: `[a-z]+`

The pattern `[a-z]+` matches one or more lowercase letters from a to z.

The server supports PCRE, ECMAScript (JavaScript), and POSIX standards.

Ada Lovelace Algorithmic Prover MCP

1 tools Official

Your AI said 'process the data' and called it an algorithm. That is not an algorithm — that is a wish. No step sequence, no edge cases, no scope limits. Ada Lovelace wrote the first published algorithm — Note G, 1843 — specifying every operation: V4 = V4 × V5, V6 = V6 − V4. This tool forces step sequencing, abstraction extraction, edge case analysis, operation decomposition, and honest scope bounding.
