What is the Regex Toolkit MCP Server?
Parsing unstructured text to find contact information is a classic LLM vulnerability. AI models often "guess" email boundaries or invent fake phone numbers when summarizing text. The Regex Toolkit MCP enforces strict mathematical patterns to guarantee 100% extraction and validation accuracy.
The Superpowers
- Flawless Extraction: Pull every single valid Email, URL, or Phone number from a giant block of text instantly into a clean JSON array.
- Zero-Trust Validation: Ensure that user inputs are structurally perfect before passing them to external databases or CRMs.
- PII Redaction Engine: Instantly mask sensitive client data (
[EMAIL_REDACTED]) before generating public reports or passing context to unsecure layers. - Privacy First (Local): Your data never leaves your infrastructure. The regex engine compiles and executes entirely locally.
Built-in capabilities (3)
Extracts all unique emails, URLs, or phone numbers from a large body of text
Redacts sensitive PII (emails, phones, URLs) from a text blob by replacing them with [REDACTED] tags
Validates if a single string perfectly matches an email, URL, or phone format
Why Claude Code?
Claude Code registers Regex Toolkit as an MCP server in a single terminal command. Once connected, Claude Code discovers all 3 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Regex Toolkit data drives decisions without human intervention.
- —
Single-command setup:
claude mcp addregisters the server instantly. no config files to edit or applications to restart - —
Terminal-native workflow means MCP tools integrate seamlessly into shell scripts, CI/CD pipelines, and automated DevOps tasks
- —
Claude Code runs headlessly, enabling unattended batch processing using Regex Toolkit tools in cron jobs or deployment scripts
- —
Built by the same team that created the MCP protocol, ensuring first-class compatibility and the fastest adoption of new protocol features

Why teams choose Vinkius for Regex Toolkit in Claude Code
The Regex Toolkit MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 3 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Claude Code only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Regex Toolkit for Claude Code
Every tool call from Claude Code to the Regex Toolkit MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Why use this instead of asking the AI to find the emails?
Because LLMs predict text probabilistically. They might miss emails embedded in weird characters (like contact@company.com. with a trailing dot) or hallucinate non-existent addresses. Regex provides mathematical certainty.
Does the PII masking send data to the cloud?
Never. The mask_sensitive_data tool runs exclusively on your local Javascript engine (V8). It acts as a local firewall, ensuring sensitive strings are redacted before any external processing happens.
What format of phone numbers are supported?
The regex captures international formats with country codes (e.g., +1, +55), optional parentheses for area codes, and spacing/hyphens commonly used globally.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
