Unlike a manifest diff
mcp_vendor_due_diligence
One decision-ready due-diligence dossier before an agent adopts or pays an MCP vendor: live MCP metadata and tool-risk preflight, DNS/CAA/certificate evidence, plus optional SEC material-filing evidence for a public company. Does not execute vendor tools or certify safety. ($0.10 USDC on Base)
