• buy_creditsA

  VARRD — Statistically Validated Trading Edges + AI Research EngineA

  Buy credits for the edge library and AI research. Default $5 minimum. Free — no credits consumed to call this. TWO PAYMENT METHODS: card (default): Returns a Stripe Checkout link for your user to click and pay. After payment, call check_balance to confirm credits were added. crypto: USDC on Base. Fully autonomous — no human needed. Three steps: 1. buy_credits(payment_method='crypto') → returns deposit address + payment_intent_id 2. Send USDC to the deposit address (use your wallet tool) 3. buy_credits(payment_intent_id='pi_...') → confirms payment, credits added instantly If you have wallet access, this is the fastest path — fully machine-to-machine.

• buy_domain_cryptoA

  instadomainA

  Start the purchase flow for a domain using USDC crypto payment (x402 protocol). Autonomous two-step payment flow — no browser required: Step 1: Call this tool to reserve the domain and get a pay_url. Step 2: Pay the pay_url using your x402 wallet: - If you have Coinbase Payments MCP: call its x402 payment tool with the pay_url. - Otherwise: run `curl -L <pay_url>` — your x402-enabled HTTP client will handle the 402 handshake and USDC payment on Base automatically. After payment succeeds, call get_domain_status(order_id) to poll until registration is complete (usually under 60 seconds). The registrant contact details are required because the domain will be registered in the buyer's name (they become the legal owner). WHOIS privacy is enabled by default, so these details are not publicly visible. IMPORTANT: Before calling this tool, you MUST first call check_domain to get the price and confirm it with the user. Args: domain: The domain to purchase (e.g. "coolstartup.com"). first_name: Registrant's first name. last_name: Registrant's last name. email: Registrant's email address. address1: Registrant's street address. city: Registrant's city. state: Registrant's state or province. postal_code: Registrant's postal/zip code. country: 2-letter ISO country code (e.g. "US", "GB", "DE"). phone: Phone number in format +1.5551234567. org_name: Organization name (optional, leave empty for individuals). Returns: Dict with order_id, pay_url (full URL to pay via x402), price_usdc, price_cents, network, and USDC contract address.

• 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.

• brainkb_create_tokenA

  brainkbA

  Generate a Personal Access Token (PAT) for browser-free auth. Requires you to be logged in already (brainkb_login or brainkb_globus_login). The token is shown ONCE and never again — copy it and set it as BRAINKB_TOKEN in your MCP/skill config; then no login or browser is needed until it expires. `name`: a label so you can tell tokens apart (e.g. 'laptop'). `days`: lifetime (default 90, server-capped). Treat the returned token like a password.

• remove_backgroundA

  OpenClipA

  Remove the background from an already-uploaded image `file` (a hashid from create_upload), returning a transparent PNG. This is FREE and only needs an account, no subscription. To use a local file: call create_upload, PUT the bytes to the returned upload_url, then pass that `id` here as `file`. Do NOT call complete_upload (that starts the paid clip pipeline); this free tool reads the uploaded file directly. Processing is ASYNCHRONOUS: this returns a `tool_job` hashid and `status: "queued"`. Poll get_tool_job_status with that `tool_job` until it reports `completed`, then it returns the downloadable PNG URL. Free usage is rate-limited per day with a per-file size cap; a clear error explains how to lift a limit.

• audit_endpointA

  KnownFixA

  Readiness audit of any agent-facing URL: MCP handshake, CORS, discovery docs (llms.txt, mcp.json), and payment-offer behaviour. First call with url alone for the FREE grade and failing-check list. For the full findings and remediations, call get_offer with productType "audit" and productId "conformance-report", pay, then call audit_endpoint again with the same url plus paymentTx and paymentOffer. This tool both previews and redeems the paid report; no separate delivery tool is needed.

• search_storiesA

  my quant doesn’t speak english — editorial discoveryA

  Find published archive records by text when you do not know an exact story ID. All space-separated terms must match as case-insensitive substrings across IDs, titles, summaries, tags, products, beats, evidence status, contributions, or source labels/release IDs. Returns newest-first stories, normalized query, count, feed receipt, and release identity, preserving evidence clocks and limitations. No relevance ranking or pagination; zero matches returns an empty list. Public and read-only; no credentials. The feed is cached for up to 60 seconds; invalid queries or unavailable/invalid feeds return a tool error. Use get_story for an exact ID or latest_stories for an unfiltered overview.

  Nefesh — Real-Time Human State Awareness for AIA

  Start free API key authorization; no existing API key needed. Returns a verification_url. Ask the user to open that URL in their browser, enter their own email, then open the verification email and confirm access for their agent. This tool does not accept email addresses and does not send email. Do not choose, invent, or submit an email on the user's behalf. Poll check_api_key_status with the returned request_id at the supplied interval. Stop if the request expires. Never create new requests in a loop.

• check_textA

  WSC - Writing Style CheckerA

  Analyze text for writing style issues: weasel words, passive voice, duplicate words, long sentences, nominalizations, hedging, filler adverbs, and research-cited AI tells. Read-only and stateless — text is analyzed in memory on the hosted server and never stored. Returns a plain-text report with each issue's line and column, the matched text, surrounding context, and the reason for AI tells; texts over 100,000 characters return an error message. This hosted server has no filesystem access — the wsc-mcp npm package adds a check_file tool for local files. It only reports issues — to auto-remove duplicate words, follow up with fix_duplicates.

• get_balanceA

  UnphurlA

  Check your pipeline check credit balance. Shows credits remaining, total purchased, total used, and lifetime free lookups count. Credits are consumed only when unknown domains run through the full analysis pipeline. Known domains (Tranco Top 100K) and cached domains (previously analysed by any Unphurl customer) are always free. If credits_remaining is 0, you can still check known and cached domains for free. To check unknown domains, purchase more credits using the "purchase" tool.

• start_deep_reportA

  Moonlings — Local Business IntelligenceA

  Launch a full overnight-grade research report on a local business: an autonomous research crew maps the competitive landscape, reads the business's and rivals' web presence, and delivers a long-form graded report with structured findings and an action list. ASYNC: this tool returns a slug immediately; the report takes roughly 10-20 minutes. Poll check_report_status, then fetch with get_report_result. Price: $9.99, charged when the report launches; if the report fails, the charge is refunded automatically. Each call starts a NEW report — do not retry a call that already returned a slug.

• buy_connectA

  agentcardA

  Connect a merchant for shopping. For merchants that need a real login (e.g. DoorDash) this opens a secure hosted browser session and returns a URL the user opens to log in; after they finish, call buy_connect_status with the pending_id to confirm. Merchants that need no login (e.g. Agentcard Flights) come back ready immediately. Use this instead of buy_link_merchant for hosted-login merchants. This tool pairs only with buy_connect_status and only tracks logins it started itself; a login link handed out by the conversational `buy` tool has no pending_id and is verified inside that same buy conversation (the user replies there, e.g. "done — I logged in").

• 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.
