What is the Phone Validator Engine MCP Server?
LLMs often accept chaotic phone number inputs or try to format them incorrectly before sending to Twilio or Zenvia. This MCP brings Google's libphonenumber-js to the Edge.
The Superpowers
- E.164 Strict Format: Cleans and formats chaotic inputs into mathematically perfect E.164 strings.
- Country Validation: Validates the exact country code and identifies fake numbers immediately.
Built-in capabilities (1)
Pass the raw phone string and optionally a country code. The engine uses libphonenumber to validate structure, detect carrier type, and format to E.164 standard. Validates and formats a phone number deterministically to E.164 standard using Google libphonenumber-js

Frequently asked questions
Does it support Brazilian numbers?
Yes, perfectly handles the 9-digit rule.
Can it extract the country?
Yes, it returns the Alpha-2 country code.
Is it local?
Yes, 100% local regex/metadata evaluation.
How does Windsurf discover MCP tools?
Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.
Can Cascade chain multiple MCP tool calls?
Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.
Does Windsurf support multiple MCP servers?
Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
