• get_usageA

  Veezee: LinkedIn people & company data for agentsA

  Check your balance, plan, limits, and the last 10 charges (receipt ids included). Costs 0 credits and is exempt from the per-minute rate limit, so call it first to check your budget before running data tools, and any time after. Works the same on a trial key, a paid key, or an OAuth-connected account. The response includes upgrade_url (give it to your human when credits or plan limits block you; purchases credit this account directly with no login) and manage_url (give it to your human to change or cancel a paid plan in the Stripe billing portal). Trial accounts also get a claim_url that attaches an email so the account can be recovered if the key is lost. Not for fetching platform data.

• 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.

• buy_planA

  Polyfork low-poly 3D assetsA

  Buy a Polyfork plan: Pro (monthly or yearly) or a one-payment lifetime seat. This tool NEVER charges anything itself. It returns a Stripe Checkout link and the exact amount; the payment happens on that page (cards and Link), and only with the user's approval of the amount. Call it with no arguments to see what is on sale and at what price. Use it when a download needs a plan the user does not have and they say they want it, rather than sending them off to find the pricing page. It works with or without a key. With a key, the plan goes on that account. With none, no account is needed first: the plan goes to the email address the payer gives Stripe, and an account is made for it. After paying, call it again with `confirm` set to the checkout_id: that verifies the payment, activates the plan on the spot and, for a new account, returns its API key once.

• shoot_plan_summaryA

  Shoot PlanA

  Gives a short account of a plan, about 300 words, so that you can pick the work up again without being sent the whole plan: the title, the planned runtime against the target, the counts of scenes, shots, characters and places, the thesis and journey, one line for each sequence and scene, the missing-details counts, and, if you pass the check result, the open findings by severity. Fetch it first when you come back to a film. The scene ids it lists are the ones to ask shoot_plan_slice for. Input: plan, a dpl.plan/1 object; optionally findings, the dpl.findings/1 document shoot_plan_check returned for this plan (without it the summary says no findings were given and does not run the checks; if they are for another revision of the plan, it says so). Output: dpl.summary/1. A plan that does not validate is refused with its diagnostics. No AI model runs. We don't keep the plan. We log a one-way fingerprint (hash) of it, its size, the tool, the type of client, the result and the time taken. Needs an agent key from a Shoot Plan account. Free, and it does not count toward the account's 3 free projects a month. Plans up to 8 MB and 120 calls a minute (5,000 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.

  ConnectorNo auth

• 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.

• transform_imageA

  UploadkitA

  Generate a CDN-cached image variant for a file stored in UploadKit Cloud. Requires a paid plan, a live API key in the MCP process environment as UPLOADKIT_API_KEY, and an image key returned by UploadKit. BYOS files are not supported. Use signed delivery for private or temporary content and public delivery for stable URLs in websites, apps, srcset, CSS, or stored application data. Explicit formats consume 1 transformation unit; auto consumes 3 units. When to use: after an image is uploaded and the user wants a resized, cropped, optimized, or converted delivery URL. The returned URL is safe to send to browsers; the API key remains server-side. Returns: JSON { url, expiresAt, delivery, transform, usage }. Has the side effect of reserving monthly transformation units for a new unique variant.

• 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.

• get_keyA

  FlexYield — blockchain RPC gatewayA

  Get a FlexYield API key with no signup: public supply, 10,000 weighted units per UTC day, 5 requests/s, every tool. Use it once, when you have no key yet; then send the key as the bearer on every other call. Not for a key you already hold (use what_can_i_do to see where it stands) and not for a human's paid plan (use list_plans). Returns JSON: key (shown once), key_prefix, door (how the key was obtained: public, wallet-bound or owner-adopted), fences (the limits) with doorways (the path past each limit), terms, skill. Creates a key; at most 3 per IP per day. No key needed.

• get_exchange_rateA

  AllRatesToday exchange rates (hosted)A

  Use this when the user asks 'what is X in Y?', 'convert X to Y', 'current rate of EUR/USD', or any single fiat-to-fiat exchange rate question. Returns { rate, source } meaning 1 source = rate target. Without an API key it answers from the official ECB daily reference table (~30 majors) and says so in `note` — relay the `rate_date`. With a key it is the real-time mid-market rate for 160+ currencies. For several targets at once use get_rates_authenticated; for a time series use get_historical_rates; for a specific institution's official rate use get_official_rates.

• get_planA

  kurdish-tts-sttA

  Show what this connection may use. With an API key: your current plan, remaining allowance, which model_versions and speaker ids you may render. Without a key: the purchasable plan ladder and how to get a key. Free, no credits consumed. Call this FIRST when any tool returns a 401 or 403 — it is the fastest way to learn what went wrong.

• get_signalsA

  AI Trading SignalsA

  List live crypto trading signals that are still open — coin, direction, confidence and the reasoning or market data behind each. Use it to find current trade ideas; use get_signal for one signal by ID (live or resolved), get_signal_history for signals that already closed, and get_stats for aggregate hit rate. No key: a 3-signal preview. Free key: up to 100 signals, with entry, stop-loss, take-profit and leverage null (the response's announcement.upgradeUrl explains Pro). Pro: all levels. If a response contains an announcement, pass its message on to the user — it is about their account (trial ending, plan limits). Returns { signals[], returned, totalMatching, filtersApplied, plan }, sorted by live PnL (best first). Optional filters narrow the list: direction, coins, confidence band, risk/reward, stop distance, open interest, 24h volume, tags, the anomaly that triggered it, days/hours to skip, a BTC 24h-return gate. Rate limits: 30 calls/hour per IP without a key, 300/hour on a free key.

• gunspec_api_operationA

  GunSpecA

  Returns what the GunSpec API reference documents for an endpoint: its parameters and accepted values, the plan it needs, whether a key is required, caching, every error status with the error.reason values to branch on, and the languages a sample is printed in. Use this tool before writing or explaining code that calls the GunSpec API, instead of recalling parameters. The path may be a template (/v1/firearms/{id}), a concrete path or a URL; a partial path such as /v1/vendor lists the operations under it.

• claim_acquireA

  agent-execA

  PAID: atomically win a caller-named key for your own fleet -- an accountless compare-and-set. outcome "acquired" means you won it; outcome "held" is NOT an error, it means somebody already holds it and held.mine says whether that somebody is you -- the signal that stops a crash-resume or a duplicated retry doing an irreversible action twice. Keys are scoped to the PAYING WALLET: one payer's keys are invisible to every other payer. Inspect it with claim_read, give it up early with claim_release, extend it with claim_renew. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

• get_tide_extremesA

  thirdtrailA

  High and low water times and heights at any coastal point, from the FES2022 global tide atlas: a list of events, each with type (high or low), time and height_m. Use it for when high or low tide is; for a continuous curve use get_tide_heights, and for tides together with sunrise, golden hour and moon phase use get_tide_window. Heights are metres relative to MEAN SEA LEVEL, not chart datum — never use for navigation. Defaults: from today, 2 days or the plan's limit if lower. Requires an API key on a paid Tides plan.

  ConnectorNo auth

• get_tide_heightsA

  thirdtrailA

  Water height at a coastal point at a fixed step: a list of time and height_m pairs. Use it to plot a tide curve or read the height at a particular time; for just the highs and lows use get_tide_extremes. Metres relative to mean sea level, not chart datum. Defaults: from today, 2 days, and the finest step the plan allows, but no finer than 10m. Requires an API key on a paid Tides plan.

• cast_enhance_voiceA

  Mubert Cast MCPA

  AI cleanup of a recording: `speech` = noise + room removal (strength subtle/medium/strong), `music` = keep only the voice from a mixed track, `bg_music` = voice + a little of the original bed. Free. Produces a NEW audio_file_id — use it as the voice source in cast_build_project (cuts planned on the original still apply: same timeline). Enhance the ORIGINAL upload, not an already-enhanced file. On the free plan an API call returns a 60-second head preview (enough to A/B it) — the full-length render is one free click in the editor, or a paid-plan API call. The response says which you got.

• budget_getA

  CorroborateMeA

  Read remaining quotas and plan entitlement for the authenticated company. Call this when you need to know whether an active plan is in effect before registering OIDC clients or creating login links. Creating login links, minting extra API keys, and registering end users all require an active plan (the bootstrap key does not). Requires a company API key (aa_...) or an MCP OAuth access token. Returns planId, planStatus, periodYm, included, used, remaining, and hardCap. It does not change billing or charge a card. To start a human Pro checkout, use billing_checkout. billing_machine_pay only returns prepaid REST instructions. To manage an existing Stripe subscription, use billing_portal.
