Live health verdicts for ~2,000 public MCP servers from the official registry, checked every 15 minutes, plus working alternatives. The same MCP endpoint also exposes Upstream tools (check_api_status, check_model_deprecation, list_recent_api_changes, list_providers, get_digest) for AI/dev API status and model deprecations; Upstream's own REST/x402 API remains at https://upstream.toolweather.workers.dev. Free tier: 1,000 calls/day per key or 50/day anonymous with no key; get a key instantly with POST /v1/keys (no email or signup). Change alerts: watch up to 3 servers per free key and receive signed HTTPS webhooks. Python urllib users: Cloudflare returns HTTP 403 'error code: 1010' for the default Python-urllib User-Agent; send any other User-Agent header. Pricing: free 1,000 calls/day per key (or 50/day anonymous, no key) and 3 watches; over quota, HTTP 402 x402 v2 exact pay-per-call (USDC on Base): $0.001/check, $0.003/live recheck, $0.01/batch of 25, $0.05 per extra watch per 30 days.
