# Freshness Validator

> Freshness Validator is an API and MCP service that scores how fresh an AI agent's context is and flags content that has changed at its source. Agents register public https source URLs, send the context they hold, and receive a freshness score (0-100), a stale flag (score below 70), flagged issues, and suggestions. Billing is per call from prepaid credits. Submitted context is scored in memory and not stored.
