Integrate SanctifAI Trust Proof-of-Human attestations. Use when an app needs cryptographic proof a human performed a task or human-in-the-loop verification.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SanctifAI Trust — Proof of Human SanctifAI Trust turns a unit of human work into a verifiable **Proof of Human**: the person confirms presence with WebAuthn (Touch ID / Windows Hello / passkey), and you get a privacy-preserving participation plus a public certificate URL (and optional on-chain seal). Raw task data never leaves the client — only `0x`+SHA-256 commitments are sent. Use this when you need to **prove a human did something** (approved a wire, reviewed content, signed off a release, completed a gig) and receive `participation_id` + `certificate_url`. **Base API:** `https://trust.sanctifai.com`. Three equal surfaces, same outcome: 1. **Embedded** — Proof of Human inside the customer's own app (`/api/presence/*`, API key on their backend). No package install. 2. **Chrome extension** — SanctifAI Chrome extension + hosted `sanctifai-presence.js` (worker-bound identity). No package install. 3. **Chat bridge** — attestations minted for an AI agent via the hosted bridge at `https://bridge.trust.sanctifai.com`. Local Trust on `localhost` is the docs site, not the production API. ## Choose a surface …

How to install
mdr add sanctifai/skills/sanctifai-trust-proof-of-human@sha256:8e69f3309f5a8707The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
