Sign Cli

A rare breed: an e-signature tool that works completely offline via PAdES with self-issued certs, then routes through Dropbox Sign, DocuSign, or SignWell when you need a third-party anchor. Exposes 19 MCP tools covering the full lifecycle: create multi-signer requests, issue scoped approval tokens, send, watch for completion, verify signed PDFs, and export hash-chained audit trails with RFC 3161 timestamps. The design keeps agents out of the signing gesture itself but lets them drive everything else: document prep, recipient orchestration, status polling, compliance checks. Ships with sandbox mode, path-traversal guards, and a parallel HTTP API. Useful when you're automating contract ops end-to-end but need a human-in-the-loop gate before ink hits paper.
