ProofX - Content Protection for Creators

A cryptographic signing tool for establishing proof of ownership and authenticity over digital content. You'd reach for this when you need to verify who created something, timestamp content creation, or build a chain of custody for files, documents, or data. The implementation uses public key cryptography to generate verifiable signatures that can prove a piece of content existed at a specific time and came from a specific source. Useful for protecting intellectual property, creating tamper-evident audit trails, or building trust systems where attribution matters. The streamable HTTP transport makes it accessible from any Claude environment without local setup.
