Signet MCP Tools
Exposes Signet's cryptographic signing primitives as MCP tools so Claude can sign, verify, and hash content directly in a conversation. You get Ed25519 signature generation and verification, SHA-256 content hashing, and identity management without leaving the chat interface. Reach for this when you want Claude to create tamper-evident receipts for data it generates, verify signed payloads inline, or prove content integrity through cryptographic operations rather than just logging output. Part of the larger Signet audit framework for AI agent actions, but works standalone for any workflow where you need verifiable proof of what was said or done. Ships as @signet-auth/mcp-tools over stdio.
