18 tools, verified live

Pulled straight from the server with tools/list on 2026-10-17.
check_mcp_server_healthread-only

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/beare

find_alternative_mcp_serversread-only

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

get_api_key

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

watch_server

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.

list_watchesread-only

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[]

unwatch_servercan modify

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}. Requir

batch_check_mcp_serversread-only

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

check_api_statusread-only

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, af

check_model_deprecationread-only

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, recommen

list_recent_api_changesread-only

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 $0.0

list_providersread-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.

get_digestread-only

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 webh

score_spendread-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

get_quotaread-only

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

spendgate_get_api_key

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 Toolweat

check_merchant

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 bar

paycheck_get_quotaread-only

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

paycheck_get_api_key

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.
