Toolweather

Read stored health verdicts for up to 25 MCP servers you already intend to call. Use at startup to vet that list. 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 ($0.01). Returns summary, checked_at, and results[] with the same verdict fields as a single check. Unknown names come back verdict unknown.

Read whether one tracked AI or developer API provider is operational, degraded, or down. Use before calling that provider, or right after 5xx, 429, or timeouts. 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.

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.

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.

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.

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.

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.

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.

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 the AI and developer API providers Upstream tracks, each with state (operational, degraded, or outage) and checked_at. Use to choose a provider id before check_api_status. Do not use it as an MCP health check (check_mcp_server_health), as the change feed (list_recent_api_changes), as a spend score (score_spend), or as a merchant check (check_merchant). No arguments. Returns the catalog only. Does not probe providers or use the Toolweather check quota. Free.

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.

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.

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.

Read how many free PayCheck merchant checks this caller has left today. Use before a run of check_merchant calls, or after an HTTP 402. Do not use it for SpendGate's free-score cap (get_quota), the Toolweather health-check quota, or to mint a key (paycheck_get_api_key, spendgate_get_api_key, or get_api_key). 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.

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.

Mint one new SpendGate API key (sg_live_…) for score_spend and get_quota. 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 for health checks and watches (get_api_key returns tw_…). No required arguments. Each call creates a different secret. Returns that secret once. Not billed, and not drawn from the Toolweather quota. label is an optional stored note, not an auth secret.

Delete one webhook subscription for this Toolweather API key and drop its pending deliveries. Use to stop alerts or to free a watch slot. Do not use it to change a webhook URL (delete, then watch_server) or to check health (check_mcp_server_health). Pass id from list_watches, not a server name. Repeating the same id deletes nothing further and returns watch not found. Returns {deleted: id}. Requires get_api_key first. Does not contact the MCP server and does not spend check quota.

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.
