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)

validate_luhn

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

FAQ

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.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
