MCP ServerScored via MCP protocol probing: initialize handshake, tools/list conformance, and ping + tool invocation performance.

Deep Validator

Validates email addresses and URLs in real time using actual DNS, HTTP, and DNSBL checks — something a native LLM cannot do. Returns a clear recommendation (safe / review / block), a confidence score, and per-check details. Free tier: 10 validations/day and 1 000 classify items/day per IP. Beyond quota: $0.0005/item (validate) or $0.00005/item (classify). Two payment rails: x402 (USDC on Base) or MPP (Tempo stablecoin). Free cost quote before any charge.
