What Agent Watch monitors
Agent Watch continuously probes MCP registry endpoints and paid agent services (x402/MPP) for:
Liveness — MCP handshake + tool list✅
Latency — p50/p95 response time✅
Schema drift — tool-list hash changes between probes✅
Auth posture — RFC 9728 metadata presence✅
Price integrity — 402 challenge vs advertised pricePhase 1
Registry liveness census (live)

Why this matters
We run a full liveness census of the official MCP registry. An arXiv census found 47.9% of advertised x402 paid hosts dead. Our own registry census (below) confirms the pattern: roughly two-thirds of registry-declared MCP endpoints do not answer. No directory publishes liveness, latency, or price-integrity data. Agent Watch is the first continuous monitoring layer for the agent economy's infrastructure.
