TEST DRIVE SASPIEN
This tool implements SASP — the Secure Agent Skills Protocol — Saspien's open protocol for authenticated provenance of agent skills. v0 covers domain-anchored provenance, manifest discovery, and content-digest verification. Signing, freshness, and revocation are arriving as the protocol rolls out.
Enter a domain, a SASP manifest URL, or an https URL and Saspien Verifier will run a live set of checks against it — real DNS resolution, a real fetch, real content-digest verification, and real manifest consistency checks. Nothing here is mocked or simulated.
Saspien Verifier — v0 (preview). This v0 checks:
WEBMCP EXPERIMENT, SASP PROVENANCE & LIMITATIONS › - Input validation (https only, no private or internal hosts)
- DNS resolution via DNS-over-HTTPS, including DNSSEC status
- SASP manifest discovery (manifest.json) and per-skill entry validation
- Content-digest (SHA-256) verification of same-origin skill artifacts
- Presence of strict-transport-security and content-security-policy headers
- Freshness and revocation status, where published
Signature, freshness and revocation pending publisher adoption.
