SecondSign — step-up auth & governance for agentic processes. MCP harness that turns 2FA/step-up boundaries into human-verified, attested state transitions.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"secondsign-mcp-harness","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
