Is toolweather live?

Yes — it answered the hub's last check (checked 4h ago). It answered 100% of checks over the last 30 days.

Is toolweather free to use?

Yes — the hub reached it with no key and no payment.

What tools does toolweather have?

18 tools: list_recent_api_changes, score_spend, check_mcp_server_health, find_alternative_mcp_servers, get_api_key, watch_server, list_watches, unwatch_server, ….

Is toolweather safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• check_model_deprecation open 4h ago

  Read whether one LLM model id is active, deprecated, or retired, plus its shutdown date and the provider's replacement. Use before hard-coding a model id, or when a call fails as model-not-found. Do not use it to see if the provider is down (check_api_status) or to list many retirements (list_recent_api_changes). Prefer model; id is only the legacy argument name. Returns summary, verdict, recommended_action (keep_using|plan_migration|switch_now|verify_with_provider), replacement, shutdown_date, evidence, and freshness. Upstream quota, then $0.003 via x402. Also callable as get_model.

• get_digest open 4h ago

  Read one daily digest of AI/dev API incidents, model retirements, pricing-page edits, and breaking MCP server changes. Use once a day instead of polling list_recent_api_changes. Do not use it for a live provider check (check_api_status) or a filtered change feed (list_recent_api_changes). Omit date for the latest issue. Returns that issue's summary and items. Free: no Toolweather quota and no webhook.

• get_quota open 4h ago

  Read how many free SpendGate scores this caller has left today. Use before a run of score_spend calls. Do not use it for the Toolweather health-check quota, for PayCheck's merchant-check cap (paycheck_get_quota), or to mint a key (spendgate_get_api_key or get_api_key). Does not consume a score and is not billed. Pass an sg_live_ key to read that key's cap; omit it only for the anonymous IP/session cap, which can reset on rotating egress. A tw_ key does not select this cap. Returns the remaining SpendGate count only.

• list_recent_api_changes unknown never probed

  List recent outages, deprecation-page edits, model retirements, and pricing-page edits across tracked AI and developer APIs. Use to see what changed in a window, or to explain a sudden integration error. Do not use it for one provider's live status (check_api_status) or for the once-a-day narrative (get_digest). Returns summary plus items with timestamps and source links. Upstream quota, then $0.01 via x402. Also callable as get_changes.

• score_spend unknown never probed

  Score one planned payment and return approve, ask_human, or block before any tool sends money. Use before a crypto transfer, gift card, subscription, or paid API call. Do not use it for uptime (check_mcp_server_health, check_api_status), to judge whether a host or wallet is trusted (check_merchant), or to read remaining free scores (get_quota). Does not transfer funds. Returns score 0-100, verdict (approve means pay, ask_human means stop and ask a person, block means do not pay), reasons, and recommended_action. Scoring is deterministic, so rewording purpose will not change the verdict. amount is USD, not token units. api_key, when set, is a SpendGate sg_live_ key, not a Toolweather tw_ key from get_api_key. Uses SpendGate's quota (100/day anonymous, 1,000/day with an sg_live_ key), then $0.001 via x402, not the Toolweather check quota.

• check_mcp_server_health unknown never probed

  Read whether one remote MCP server, and optionally one tool on it, is safe to call right now. Use before adding or calling that server, or after its calls fail or time out. Do not use it to search by capability (find_alternative_mcp_servers), to vet a list (batch_check_mcp_servers; stored verdicts only), or to subscribe to later outages (watch_server). A result older than 5 minutes, or fresh/bearer_token, runs one read-only initialize and spends a live-check credit (200/day, then the cache). Counts on the Toolweather quota (1,000/key or 50/day anonymous). Returns summary, verdict (safe|caution|unsafe|unknown), recommended_action (call_it|call_with_care|use_alternative|verify_yourself), reasons, latency_ms, auth, last_tool_change, checked_at, and freshness. Also callable as is_safe_to_call.

• find_alternative_mcp_servers unknown never probed

  Search the Toolweather index for healthy MCP servers by capability, or for a replacement for one broken server. Use when check_mcp_server_health is unsafe or unknown, or when you lack a capability. Do not use it to judge one server you already chose (check_mcp_server_health) or to subscribe to later outages (watch_server). Does not call those servers and does not spend a live-check credit; unsafe rows are dropped. Returns summary, checked_at, and alternatives[] with server, url, verdict, latency_ms, and matching_tools. Counts on the Toolweather daily quota. Also callable as suggest_alternatives.

• get_api_key unknown never probed

  Mint one new Toolweather API key (tw_…) for health checks and watches on this server (1,000 calls/day, 3 watches). Use it once per install, then send that key as the X-API-Key header. Do not call it every turn, and do not use it when you need a SpendGate key (spendgate_get_api_key returns sg_live_…) or a PayCheck key (paycheck_get_api_key returns pc_live_…). Takes no arguments; the caller network is the limit. Each call creates a different secret. Returns api_key once, plus daily_limit and watches_limit; later calls cannot fetch it again. A few new keys per network per day, then reuse an existing key. Health checks also work with no key at 50 calls/day.

• watch_server unknown never probed

  Create one HTTPS webhook subscription for an indexed MCP server's verdict, auth requirement, or breaking tool-list change. Use instead of polling check_mcp_server_health. Do not use it to read health now (check_mcp_server_health) or to list subscriptions (list_watches). Requires a Toolweather key from get_api_key. The same server and webhook_url do not create a second watch; a different URL does. Three watches are free; each extra watch is $0.05 for 30 days via x402. Returns id and a one-time secret for the signature header. Toolweather later POSTs alerts to the webhook_url you supply. Does not spend the daily check quota.

• list_watches unknown never probed

  List webhook subscriptions stored for the Toolweather API key on this request, including delivery health. Use to copy a watch id before unwatch_server, or to see failures. Do not use it to learn if a server is up (check_mcp_server_health) or to create a subscription (watch_server). No arguments and no quota charge. The key is the X-API-Key header; anonymous callers are rejected. Returns watches[] (id, server, webhook_url, active, disabled_reason, last_known, consecutive_failures, last_delivery) and free_tier. Does not reveal webhook secrets and does not probe servers.

Do not use it for a live handshake or auth detail (check_mcp_server_health) or to discover servers by capability (find_alternative_mcp_servers). Does not contact the remotes and never spends a live-check credit. Each name still counts as one Toolweather quota call; over quota the batch is one x402 charge ($0.10). Returns summary, checked_at, and results[] with the same verdict fields as a single check. Unknown names come back verdict unknown.

Do not use it for an MCP server (check_mcp_server_health) or a model id (check_model_deprecation); ids come from list_providers, not URLs. Does not invoke the provider's API. Returns summary, verdict, recommended_action, open incidents, affected components, checked_at, and freshness (about every 4 minutes). Uses Upstream's quota, then $0.003 via x402, not the Toolweather check quota. Also callable as get_status.

• check_merchant unknown never probed

  Decide whether an autonomous agent should pay one merchant, host, or wallet, and return trusted, unknown, suspicious, or block. Use immediately before a payment, a checkout redirect, or a transfer to a new 0x address. Do not use it to send money, to score a dollar amount (score_spend), or to read remaining checks (paycheck_get_quota). Does not sign transactions or hold wallet keys. target is a bare domain, an https URL, or a 0x address with 40 hex characters. amount_usd and category are ignored, so changing them does not change the verdict. trusted is only the published allowlist of known AI and developer APIs on https port 443. A new or random domain is never trusted. A wallet is never trusted. If the URL contains an embedded 0x address, this scores the host only; pass the bare address to score the wallet. api_key, when set, is a PayCheck pc_live_ key, not a Toolweather tw_ key from get_api_key and not a SpendGate sg_live_ key. Uses PayCheck's quota (100/day anonymous or an anon: bundle client, 1,000/day with a pc_live_ key or a hex Toolweather bundle client), then $0.001 via x402, not the Toolweather check quota. The same target for the same caller is idempotent for 60 seconds and does not consume a second check.

Does not consume a check and is not billed. Pass a pc_live_ key to read that key's cap. A tw_ key does not select this cap. A hex x-tw-bundle-client (Toolweather key hash) is the 1,000/day tier; an anon: bundle client stays at 100/day. Returns subject_kind, limit, used, remaining, and resets_at for PayCheck only.

• paycheck_get_api_key unknown never probed

  Mint one new PayCheck API key (pc_live_…) for check_merchant and paycheck_get_quota. The key raises the merchant-check allowance from 100 to 1,000 per UTC day. Use it once, then pass the secret as api_key on those tools. Do not call it every turn, and do not use it when you need a Toolweather key (get_api_key returns tw_…) or a SpendGate key (spendgate_get_api_key returns sg_live_…). No arguments. Each call creates a different secret, returned once. Not billed, and not drawn from the Toolweather quota. Limited to 10 new keys per caller IP per UTC day.
