What is the Luhn CC Validator MCP Server?
LLMs cannot perform complex algorithmic validation like the Luhn check. This results in agents trying to process fake or mistyped credit card numbers, burning API limits and triggering anti-fraud systems. This MCP adds pure, zero-latency validation to the edge.
The Superpowers
- Pre-Flight Validation: Instantly block mathematically invalid credit card numbers before making costly Stripe/Adyen API calls.
- Brand Detection: Accurately identifies Visa, Mastercard, AMEX, and Discover purely based on mathematical prefixes.
Built-in capabilities (1)
Pass the card number string and receive validation status plus card brand detection (Visa, Mastercard, Amex). Validates credit card numbers using the mathematical Luhn algorithm and detects the card brand
Why VS Code Copilot?
GitHub Copilot Agent mode brings Luhn CC Validator data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 1 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

How Vinkius secures
Luhn CC Validator for VS Code Copilot
Every tool call from VS Code Copilot to the Luhn CC Validator MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Does it process payments?
No, it purely validates the mathematical checksum of the number. It does not contact any bank.
Is it secure?
Yes, 100% local evaluation inside the edge worker memory. No network requests are made.
What brands are supported?
Visa, Mastercard, American Express, and Discover are instantly identified.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
