MCP server monitoring API (6h checks, 30 days). Same as POST /v1/watch, but the server is re-audited every 6 hours for 30 days. HMAC-SHA256 signed webhook on tools/list fingerprint or grade changes (and unreachable/recovered). Returns watch_id, the signing secret (shown once) and the baseline. Never charged for unreachable or blocked URLs or a full watch list. Search intents: mcp server monitoring, mcp uptime, mcp tool change alerts, mcp webhook alerts, watch mcp server, mcp drift monitor.
