Tool of io.github.mercuryx402/mercury-x402-mcp

declared in 1.0.0

Notarize any content (inline ?content= or a fetched ?url=) into a signed, offline-verifiable provenance receipt — sha256 contentHash + witnessed timestamp, attested by Mercury's pinned key. Deterministic, keyless, no LLM. The signed receipt is the product: it witnesses that these exact bytes existed in this exact form at this time (the one thing your own sha256() can't — a third-party witness). — $0.008/call
