Viridis MCP Security Preflight

A human read this entry. That is the one thing true of everything on the list. Beyond that: the endpoint answered an x402 request when we knocked it, on the date shown. That date is the claim — not a word, a date. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."

Deterministic static preflight for caller-supplied MCP manifests that checks endpoint and authentication declarations, closed tool schemas, approval-policy conflicts, and prompt-injection indicators, returning an input-redacted signed receipt after x402 USDC settlement on Base.
