Wraps CertNode's cryptographic signing API to generate verifiable provenance receipts for AI outputs at generation time. Each signature includes three-layer timestamps (internal, RFC 3161 TSA, optional Bitcoin anchor) and produces a receipt ID verifiable by anyone without an account. Targets EU AI Act Article 50 compliance and FRE 902 self-authenticating digital evidence standards. Reach for this when you need court-grade or regulator-grade proof of what your AI actually generated, particularly for customer disputes, eDiscovery, or procurement gates that ask how you audit AI. The MCP integration adds signAIOutput to Claude Desktop and other MCP clients. Works across any model, but if you only use Claude and never expect to change, you might wait for Anthropic's native signing if they ship it.
