Compatible with every major AI agent and IDE
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 Cline?
Cline operates autonomously inside VS Code. it reads your codebase, plans a strategy, and executes multi-step tasks including Regex Toolkit tool calls without waiting for prompts between steps. Connect 3 tools through Vinkius and Cline can fetch data, generate code, and commit changes in a single autonomous run.

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 does Cline connect to MCP servers?
Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.
Can Cline run MCP tools without approval?
By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.
Does Cline support multiple MCP servers at once?
Yes. Configure as many servers as needed. Cline can use tools from different servers within the same autonomous task execution.
