How this service works
Toolweather suite: is this MCP server healthy and safe to call right now? 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. No subscription. See /v1/pricing.
Output
Returns a summary string and a results array where each entry contains the health verdict (up/down/degraded) and working alternative servers for each queried MCP server, as checked within the last 15 minutes.
Example use cases
Pre-flight check for agent tool stack
“Before my agent runs its next task, check if all these MCP servers are healthy and ready to use: 'sequential-thinking', 'memory', and 'fetch' — and if any are down, tell me what alternatives are available.”
Debugging a broken agent pipeline
“My agent pipeline is failing — can you batch-check the health of these MCP servers to see which ones are currently down: 'puppeteer', 'postgres', and 'slack'?”
Nightly health audit of MCP dependencies
“Run a health check on this list of MCP servers we depend on — 'filesystem', 'github', 'brave-search', 'everart', and 'google-maps' — and give me a summary of which are up, which are down, and any working alternatives for the broken ones.”
Technical details
Endpoint
POSThttps://toolweather.toolweather.workers.dev/x402/batch_check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check the health of multiple MCP servers in a single round-trip rather than querying them one at a time; it is specifically optimized for batch operations against the ~2,000 servers in the official MCP registry, checked every 15 minutes, and surfaces working alternatives automatically.
Side effects
- HTTP 402 when daily quota is exceeded (50 anonymous or 1,000 keyed calls/day) — requires x402 micropayment of $0.001 per check
- HTTP 403 from Cloudflare (error code 1010) when using default Python-urllib User-Agent — fix by sending any other User-Agent header
- Invalid or unrecognized server identifiers return unknown/not-found verdicts
- Empty servers array returns a validation error
