Implement the AP2 Verifiable Digital Credentials (VDC) framework — tamper-evident, cryptographically signed credentials that form the trust foundation for agentic payments. Use when working with the overall VDC architecture, credential issuance, verification, and holder binding.
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
# AP2 Verifiable Digital Credentials (VDC) Framework ## Before writing code **Fetch live docs**: 1. Fetch `https://ap2-protocol.org/ap2/specification/` for the VDC framework specification 2. Fetch `https://ap2-protocol.org/overview/` for VDC conceptual overview 3. Web-search `site:github.com google-agentic-commerce AP2 src/ap2/types mandate` for VDC type definitions 4. Web-search `ap2 protocol verifiable digital credentials VDC` for community guides ## Conceptual Architecture ### What VDCs Are Verifiable Digital Credentials (VDCs) are **tamper-evident, portable, and cryptographically signed digital objects** that serve as the trust building blocks for AP2 transactions. They provide: - **Non-repudiation** — Signed credentials prove who authorized what - **Tamper evidence** — Any modification invalidates the signature - **Portability** — Credentials can be passed between agents and systems - **Selective disclosure** — Only necessary data is revealed to each party ### VDC Credential Format AP2 VDCs use the **SD-JWT with Key Binding (+kb)** format, enabling selective disclosure and cryptographic holder binding. …

How to install
mdr add orcaqubits/agentic-commerce-skills-plugins/ap2-vdc-framework@sha256:3c03422c686b1324The line at the top of this page pins the label git:20260914.08f85a3, 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.
