# Attest > A bank asks a vendor a security control question. The vendor answers and attaches > evidence its own agent produced. Two gates decide whether that evidence supports > the answer before it is recorded. - MCP endpoint: https://attest-tprm.zubairzafar480.workers.dev/mcp (attest_list_vendors, attest_list_controls, attest_assess) - Agent card: https://attest-tprm.zubairzafar480.workers.dev/.well-known/ai-agent.json - REST: https://attest-tprm.zubairzafar480.workers.dev/api/vendors, /api/controls, /api/run?vendor= - Source: https://github.com/zubair480/attest The severity counter counts blocking findings. The relevance judge asks whether the evidence can answer the control at all. Neither overrides the other: a disagreement returns ESCALATED and records nothing, because that is the case a person should read. Try ACC-01 against both vendors. The counter refuses one and clears the other on evidence that answers neither.
