Agent-first e-signature MCP server with **offline PAdES signing** and hash-chained audit. The same 19 tools / 4 prompts / 12 resources are reachable via stdio (`npx @drbaher/sign-cli mcp serve`) for local agents and over HTTP for remote ones. **Architectural claim:** an LLM agent can drive every step of a contract workflow except the actual signing gesture, which stays gated behind a human via per-signer approval tokens (TTL-bounded, scoped to one email, single-use).

Pre-sign safety checks (`--require-hash`, `--require-title`, `--require-signer-email`) throw structured errors *before* any state mutation — so an agent that computed a hash earlier can refuse to sign if the document was swapped mid-flight. **Highlights:** - Fully-offline PAdES signer (real PKCS#7, self-issued X.509) - Hash-chained audit log with append-only DB triggers + RFC 3161 timestamping - Read-only mode (`--read-only true`) returns `FORBIDDEN_READ_ONLY` for mutating tools - Multi-provider routing (local / Dropbox
