"Using Claude to Check the Current Weather Without an API Key" matching MCP tools:

• check_api_key_statusA

  Nefesh — Real-Time Human State Awareness for AIA

  Check a pending API key authorization using its request_id. Use request_id exactly as returned by request_api_key, never an email. Poll every 10 seconds. awaiting_user means the user must open the URL; pending means email verification is still required. ready returns the API key once only. Store it and include it in all subsequent HTTP calls. Stop on expired; ask the user before starting another authorization.

• delete_api_keyA

  governance-platformA

  Permanently delete one of the caller's API keys. DESTRUCTIVE — agents using the deleted key will receive auth errors immediately. The Blueprint a key was tied to (if any) is NOT affected; only the credential is revoked. To delete a Blueprint and all its keys, use delete_blueprint. The target key can be specified two ways: - As the full key string (gai_...). - As a key_id (SHA-256 hash from list_api_keys).

• get_my_productsA

  PartleA

  List products created by the authenticated user. Authenticated. OAuth (scope `products:read`) preferred; `api_key` fallback. Use when the user asks "what have I listed?" or before bulk operations like updating prices across multiple of their products. Distinct from `search_products`, which searches the public catalog without owner scoping. Read-only. Args: limit: Max results (1–200, default 50). api_key: Optional API key (`pk_*`, generate at /account). Used when there is no OAuth token, and also when the OAuth token lacks the required scope — an explicitly passed key overrides an ambient token that is scoped too narrowly. An invalid or revoked token still fails regardless. Omit when using OAuth. Returns: A list of products in the same shape as `search_products`. Returns ``[{"error": ...}]`` on auth failure.

• create_api_keyA

  Molt2MeetA

  Generate a new API key for your agent. The full plaintext key (m2m_...) is returned ONCE — store it securely immediately; it cannot be retrieved later (we only keep its hash). Use keyName to identify the key's purpose (e.g. 'production', 'staging'). Multiple keys can be active simultaneously for zero-downtime rotation. Requires: an existing API key from register_agent. Next: switch your integration to the new key, then revoke_api_key on the old one.

• get_api_keyA

  TunnelMind Data APIB

  Returns the tier, label, masked owner email, creation date, last-used timestamp, today's request count, and daily request limit for the API key used in this request. Useful for agents that need to monitor their own quota consumption. Use this tool when: - You want to check how many requests your key has used today. - You need to know your current tier or daily limit. - You want to confirm that your API key is active. Do NOT use this tool when: - You want to manage multiple keys — this endpoint only reflects the calling key. - You need tracker data — use the tracker endpoints instead. Inputs: - No body or query parameters. Auth is from the `Authorization: Bearer` header. Returns: - `tier`: free, supporter, pro, or enterprise. - `requests_today`: integer count from KV (best-effort; resets at UTC midnight). - `limit_per_day`: null for enterprise (unlimited). - `last_used`: ISO 8601 timestamp, may be null if never used. Cost: - Free. Does not count against the daily request limit. Latency: - Typical: <150ms, p99: <400ms.

• get_variable_relationshipsA

  hypathesisA

  Retrieve analyzed variable relationships for a completed paper. Only returns results when get_analysis_status reports status='Ready'. Without an API key (anonymous): returns the relationship list with source, target, and direction — but detailed reasoning is available only with an API key. Sign up at https://hypathesis.com to get one. Args: file_id: The file_id returned by the /upload endpoint. authorization: Optional. API key as 'Bearer hk_...' or 'hk_...'. session_token: Optional. The session_token returned by /upload for anonymous uploads. Returns: Authenticated: full details (source, target, directed, reason per relationship; name, measure per variable). Anonymous: gated (source, target, directed per relationship; name per variable; sign_up_url for full access).

• send_faxA

  SendThisFaxA

  Submit an uploaded PDF for faxing. Step 1 (before this tool): upload the PDF over plain HTTP multipart, using any HTTP client you have — shell, JavaScript fetch with FormData, Python, etc.: curl -F "file=@document.pdf" https://www.sendthisfax.com/api/upload fetch("https://www.sendthisfax.com/api/upload", {method: "POST", body: formDataWithFile}) The response contains fax_public_id and page_count. PDFs must be unencrypted, at most 50 MB and 1000 pages. Step 2: call this tool with the fax_public_id and the recipient fax number. Two modes: - With an API key (Authorization: Bearer stf_live_... on this MCP connection): the fax price is debited from the prepaid credit balance and sending starts immediately — no checkout, no browser. sender_email and billing_country are optional (they default to the key's records). Buy credits at https://www.sendthisfax.com/en/credits. - Without an API key: sender_email and billing_country are REQUIRED and the tool returns a checkout_url the USER must pay in a browser; the fax is sent automatically once paid. In both modes, poll get_fax_status until status reaches "delivered" or "failed" (failures after payment are auto-refunded). For integration testing, +19898989898 is the designated test recipient number.

• adopt_compute_instanceA

  BorealHostB

  Turn an instance you are ALREADY running into a persistent volume. Use this when you launched something, set it up, and then decided you want to keep it. Nothing reboots and no data moves — the machine you have becomes the volume, and you can detach it afterwards to stop paying for compute while keeping the machine. Beats creating a volume and rebuilding. Only instances launched with an ssh_public_key qualify. One launched with your own user_data carries only your key, and a key cannot be added to a machine we cannot already log into — check "managed_ssh" on the instance. Requires: API key with write scope, and an active subscription. Args: instance_id: A running lsw.* instance you own name: Label for the volume (defaults to the instance name) Returns: Volume dict with state "attached", wrapping that same instance. No snapshot exists yet — the first one is taken on detach or snapshot. Errors: CONFLICT: Not running, already a volume, BorealHost Metal, or launched without BorealHost management access

• namesniper_checkA

  NameSniperA

  All-in-one brand name check: domain availability across TLDs, username availability across the major social platforms, an optional 0-100 brand score, and USPTO trademark screening. Returns JSON with per-TLD and per-platform results (each with an availability verdict and 0-1 confidence), availability summaries, brandScore, and trademark risk. Use namesniper_check_domains or namesniper_check_social instead when only one dimension is needed. Free without an API key (rate-limited; trademark is skipped and Instagram/TikTok/X return best-effort HTTP confidence); a paid key unlocks verified accuracy on those platforms plus trademark screening.

• propline_create_free_api_keyA

  PropLine — Sports Betting Odds & Prop ResolutionA

  Create a free personal PropLine API key for the user and EMAIL it to them. Use this when the user wants their own key — e.g. they hit a shared-demo-key rate limit, a paid field came back redacted, or they ask how to get a key. Only call it with an email address the user explicitly gave you for this purpose in this conversation; never guess, reuse one from elsewhere, or sign up a third party. The key is never returned here — it goes to that inbox, with instructions to reconnect this assistant using it. Free tier: 1,000 requests/day, no card. If the address already has a key, the key is re-sent (at most once a day).

• create_billing_checkoutA

  Algenta MCP ServerA

  Create a Stripe Checkout session for the active organization and return its hosted checkout URL. The user completes the purchase in the browser; nothing is charged by this call itself. Requires an owner API key. plan defaults to developer; an unsupported plan fails with invalid_plan. Use get_billing_info to check the current plan and create_billing_portal to manage an existing subscription.

• get_wedding_informationA

  The Hill KinabaluA

  Retrieve The Hill Kinabalu’s official public wedding venue and 2026/2027 package information, including capacity, event sizes, starting package prices, key inclusions, add-ons without prices, payment structures, and enquiry links. Use this when someone asks about weddings, wedding packages, the event venue, guest capacity, package pricing, or how to enquire. This tool does not check date availability or submit an enquiry.

• discovery_loginA

  DiscoA

  Get a new API key for an existing Disco account. Sends a 6-digit verification code to the email address. Call discovery_login_verify with the code to receive a new API key. Use this when you need an API key for an account that already exists (e.g. the key was lost or this is a new agent session). Returns 404 if no account exists with this email — use discovery_signup instead. Args: email: Email address of the existing account.

• revoke_api_keyA

  Molt2MeetA

  Permanently deactivate an API key by its database ID. Requests using the revoked key are rejected immediately. Use this after rotating to a new key via create_api_key. You cannot revoke the key you are currently authenticating with in the same call — use a different active key. Requires: API key from register_agent.

• health_checkA

  TunnelMind Data APIB

  Returns a minimal status object confirming the API is alive. Use this to verify connectivity before chaining other calls, or as a liveness check in a workflow. Use this tool when: - You need to verify the API is reachable before starting a multi-step investigation. - A prior call failed with a 503 or 504 and you want to confirm the service recovered. - You are debugging connectivity from a new environment. Do NOT use this tool when: - You want actual tracker data — use `get_domain` or `search` instead. - You want to check a specific domain — this returns nothing domain-specific. Inputs: - None. Returns: - `ok`: always true if the API is up. - `ts`: ISO 8601 timestamp of the server's current time. Cost: - Free. No API key required. Not rate-limited. Latency: - Typical: <50ms, p99: <200ms.

• revoke_api_keyA

  TunnelMind Data APIB

  Permanently deactivates the API key used to make this request. This action is irreversible. After revocation, the key will return 401 on all subsequent calls. Use this tool when: - You want to rotate your API key (revoke old, then provision a new one). - You believe your key has been compromised. Do NOT use this tool when: - You want to check quota — use `get_api_key` instead. - You intend to keep using the API — this is permanent. Inputs: - No body or query parameters. Auth is from the `Authorization: Bearer` header. Returns: - `revoked`: true. - `note`: confirmation that the key is permanently revoked. Cost: - Free. Does not count against the daily request limit. Latency: - Typical: <150ms, p99: <400ms.

• cancel_spot_orderA

  CoinRithm Agent TradingA

  Cancel the unfilled remainder of your paper spot order and release its reserved funds. Requires trade:spot scope; get orderId from list_open_orders. Does not reverse filled trades. Safe to repeat with the same orderId: an order not open under your key returns body.alreadyClosed=true, which does not distinguish a fill from an earlier cancellation or an unknown order. Use get_my_trades to check fills. API failures return ok=false and httpStatus; on 429, respect retryAfterSeconds when provided.

  vivideoA

  Check whether a Vivideo API key is present on this request. Call this FIRST. Returns { configured: boolean }.

• register_accountA

  HPSILab Quant FinanceA

  Register a free hpsilab account for yourself, with no human involvement, and receive an API key immediately. Call this when the user has no API key yet and asks to sign up from here, or when a refusal's `next_actions` names register_account and the user agrees. This is the only tool that works without an API key. You do not need a password, a wallet, or a web browser. The account is bound to you server-side, so calls you make after this are metered as your account even though you cannot change your own Authorization header. The account is created unverified, with only a capped evaluation allowance and no trial Credits, until the email address is confirmed; confirming it grants the one-time 100-Credit Registered Trial (14 days). Ask the human you are working with to click the link in the email that will arrive. Calling again from the same caller returns the same account with a fresh key; an address that belongs to another account is refused. A valid user email address is required. Do not call this tool with an empty or fabricated email address. If the user's email is unavailable, ask the user to provide it before calling register_account. Args: email: The real user email address that will receive verification.
