RegexForge

When you need a regex but don't want to wrestle with backtracking bugs or LLM hallucinations, this server synthesizes patterns from labeled examples using pure symbolic logic. It exposes a single regexforge_synth tool over MCP that takes your match and non-match cases and returns a deterministic regex drawn from a bank of 67 templates. The engine runs zero LLM inference at serve time, instead relying on proof matrices and backtracking audits. You get 50 free credits on signup, then it's $0.002 per synthesis call. Reach for it when you're building validation pipelines, data parsers, or any workflow where you need a provably correct pattern without the trial and error.
