"Checking Domain Name Availability" matching MCP tools:

• 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.

• search_domainsA

  Orivox AI Website BuilderA

  Search real-time domain availability and prices (via Name.com). Pass a keyword for suggestions, or include ONE full domain name anywhere in the query ("orivox.ai", "www.orivox.ai", even inside a short phrase) to also get that exact domain availability-checked and returned as the FIRST result marked exact:true. Response markers: exact_domain = the exact answer is in the list; exact_check_unavailable = the exact check failed, the list is keyword suggestions only (relay the included note); NEITHER marker = no single domain was recognized (bare keyword, or two+ domains in one query) and NO exact check ran -- if the user asked about specific domains, use check_domain per domain. Returns suggestions as {domain, available, price, premium, renewal_price} sorted purchasable-first (exact match first when present), plus registrar_env ("production" or "sandbox"). ALWAYS mention two pricing traps when recommending: premium=true is an aftermarket domain (first-year price can be thousands, renewal differs), and renewal_price much higher than price is a first-year-discount cliff (e.g. $3.99 year one, $48.99/year after) -- quote both numbers. If the response carries sandbox=true, relay the included caveat to the user in their language and do not present results as real availability. This is a READ: searching never reserves, registers, or charges anything. STOP after presenting the results. Do NOT call get_domain_purchase_link in the same turn: that tool is the PAYMENT step, and the user is still choosing. Report the names, prices and renewal cliffs, then wait. Only once the user picks ONE domain and says they want to buy it does the purchase link belong in the conversation -- a payment link handed to someone who has not decided is clutter at best and pressure at worst. Searching more, or checking another name with check_domain, needs no link at all.

• check_domainA

  Orivox AI Website BuilderA

  Authoritative availability check for ONE exact domain (e.g. "is orivox.ai free?") -- use this, not search_domains, when the user names a specific domain. Returns {domain, available, price, renewal_price, premium, registrar_env}. premium=true means aftermarket pricing (quote it explicitly); a renewal_price far above price is a first-year-discount cliff -- always tell the user both numbers. This is a READ: it never reserves, registers, or charges anything.

• check_domainsA

  Porkbun (official)A

  Check up to 25 domains for availability and price in ONE call. Prefer this over calling `check_domain` in a loop whenever you have more than one name: Porkbun chunks availability checks per registry, so a batch is materially less work than the same names individually, and it draws on a separate budget of 200 domains per 60 seconds (counted per domain, not per call) rather than the single check's 10 per 10 seconds. **Read all three result lists — they mean different things.** `domains` is keyed by domain name and each value has the same shape as `check_domain`'s response. `invalid` holds entries that are not checkable at all (not a domain, unsupported TLD); one bad entry does NOT fail the call, so the other names still come back answered. `unresolved` holds domains the registry did not answer for — these are **neither available nor taken**, and reporting them as unavailable would be wrong. Retry those. Duplicates are removed before the budget is charged. More than 25 names returns BULK_CHECK_TOO_MANY and checks nothing, rather than silently truncating, so split longer lists yourself. Synchronous, no polling — 25 mixed TLDs answers in roughly three seconds. One exception to watch: a few registries accept only a few domains per command and .de accepts exactly one, so a batch heavy in those TLDs returns BULK_CHECK_TOO_SLOW without checking anything. Group .de names into their own small calls. RATE_LIMIT_EXCEEDED with `reason: SUSTAINED_BULK_CHECKING` means the account has been checking at scanning volume (hundreds of names an hour, few registrations) and is held to 50 names per 5 minutes for a day. Do not retry in a loop: check only names the user might actually buy, wait `retryAfter`, or tell the user support can raise the limit for a legitimate high-volume use.

• sigil_verify_domainA

  TunnelMind Data APIB

  Confirms a publisher controls a domain by checking for a DNS TXT record the owner publishes under `_tunnelmind.{domain}`. A DNS record can only be set by whoever controls the zone, so its presence proves control — a stronger signal than ads.txt, which is just a file anything in the request path can serve. Use this tool when: - You want proof a publisher actually owns the domain it claims. - You are distinguishing publishers who have opted into Sigil verification. Inputs: - `domain` (query, required): Publisher domain. `www.` and scheme stripped. Returns: - `verified`: true (record found), false (absent), or null (DNS lookup failed). - `expected`: the exact TXT record the owner must publish to verify. - `found_records`: TXT values currently present at `_tunnelmind.{domain}`. - `checked_at`: ISO 8601 timestamp of the live DNS lookup. Cost: - Counts as one request against the daily rate limit. Latency: - Typical: <300ms (one DNS-over-HTTPS lookup).

• search_titlesA

  ottasiaA

  Search OTTASIA's catalog for movies or TV shows by name. Returns multiple candidates with year, type, brief overview, and country-aware OTTASIA link. Use this when a user asks 'find me X' or when a query is ambiguous (e.g. 'joker', 'the office') and you need to clarify which title they meant before checking availability. Use where_to_watch instead when the user has already named a specific title and country and just wants the streaming providers.

  Domain RDAP MCPA

  Check whether a domain name is registered, using real-time RDAP data (the IETF-standardized successor to WHOIS). Use for "is domain-x.com available/registered", "who is domain-x.com registered with", or "when does domain-x.com expire" style questions. `domain` is a bare domain like "example.com" -- no protocol prefix, no path, no spaces. If the domain is NOT registered, returns `{"domain": ..., "registered": false}` -- this is a normal, meaningful answer (the domain is available), not an error. If the domain IS registered, returns `{"domain", "registered": true, "status", "registered_date", "expiration_date", "last_changed_date", "registrar"}`. `status` is a list of RDAP status codes (e.g. "active", "client transfer prohibited"). Dates are ISO 8601. `registrar` is the registrar's name, or null if the registry redacts it for privacy. For obviously malformed input (not a domain -- e.g. missing a dot, has spaces, or includes a protocol like "https://"), returns a clean `{"error": ...}` instead of calling the API.

• leads_get_personA

  Manifold MCPA

  The full record of one person: real name, title, company, location, LinkedIn, employment history and education. No email. Use when: filling in a search row by id, "who is the head of growth at acme.com", checking a person's current role before outreach. Not for: the email, use leads_get_email (the paid reveal). Many people at once, use leads_search_people. Returns: Record. id, first_name, last_name, headline, title, title_start, seniority, company, company_domain, company_id, company_linkedin_url, company_employees, company_industry, location, linkedin_url, has_email, summary, employment_history[] (company, title, start, end, current; newest first), education[] (school, degree, field, start, end), skills[], languages[]. Dates are YYYY-MM. null or empty = the provider does not hold it; looked up by name and domain, the history is the current role only and education, skills and languages are empty. NoData when nobody matches. Give id, or first_name + last_name + domain, or linkedin_url. Cost: 9 credits by id or linkedin_url, 3 by name and domain, 1 on NoData. Cached 30 days. Example: {"first_name": "Jordan", "last_name": "Blake", "domain": "northstaranalytics.io"}

• leads_get_domain_emailsA

  Manifold MCPA

  Email addresses known for a website's domain, with name, role, confidence and where each was seen. The contact-finding tool for link outreach. Use when: "find someone to email at these sites about a backlink", "who runs content at example.com", "get contacts for the referring domains of X". Not for: one named person, use leads_get_email. People by title across many companies, use leads_search_people. Checking an address works, use leads_get_email_status. Choosing which sites to contact, use seo_get_referring_domains, seo_get_backlinks, seo_get_domain_ratings. Returns: List, highest confidence first. rows[]: domain, email, first_name, last_name, position, department, seniority, decision_maker, type (personal | generic), confidence (0 to 100), verification_status, sources[] (url, last_seen_at; empty = inferred from the domain's pattern), linkedin_url, twitter, phone. domains[]: domain, pattern (the address format, for example {first}.{last}), organization, accept_all (true = the server takes any address, so no address there can be proven), webmail, disposable, linked_domains[], rows_available. errors[] lists domains that failed. Addresses come back unverified for the most part; verify the shortlist with leads_get_email_status, not the whole list. Cost: 1 credit per domain + 30 per domain that returns addresses, whatever the limit. Default one domain with 30 addresses = 31 credits. Cached 30 days. Example: {"domains": ["example.com"], "department": ["marketing", "communication"], "type": "all"}

• domainsA

  SuprsonicA

  Find domain names and the extensions that fit a business. Returns, by mode, name ideas with prices, extensions that fit with reasons, one name across extensions, availability for a list of domains, prices per extension, or the extension catalog. Use to name a business or check domains before buying one; it never registers or buys a domain. For facts about a domain that is already live use site-intel. mode decides which fields apply: company_name and description for the suggest modes, query for search-extensions, domains for check-availability, tlds for pricing. Cost: suggest-names 5 credits, suggest-extensions 3 credits, search-extensions 2 credits, check-availability 1 credit, pricing 1 credit, tlds 1 credit, charged only when a call succeeds.

• check_domainA

  Porkbun (official)A

  Check whether a single domain is available for registration and what it costs. Returns availability (`avail: yes|no`), registration price, renewal price, transfer price, and (for premium domains) extended pricing details. Pricing is in USD. An internationalized name (IDN) also returns `idnLanguages`, the languages its registry accepts; `register_domain` needs one of them as `idn_language`. For a domain already in the user's account the result has `inYourAccount: true`: the top-level `price` is still the registration price, and the renewal price is `additional.renewal.price` (use that, or a `renew_domain` dry run, before renewing). For a domain registered to someone else it adds `aftermarketSearch`: the name may be for sale, so call `search_aftermarket` before telling the user it is unavailable. Use this BEFORE register_domain to confirm cost — Porkbun rejects registrations whose `cost_cents` doesn't match the current quote. **Checking more than one name? Use `check_domains` instead** — it takes up to 25 in a single call and draws on a separate, more generous budget (200 domains/minute against 10 checks/10s here), because Porkbun chunks checks per registry and a batch costs less than the same names one at a time.

• hemmabo_check_availabilityA

  HemmaBo Host Booking EngineA

  Use this tool to answer "is it free these dates?" for one known propertyId — a yes/no with conflict details, no signed price. For the final quoted price and booking link, use vrp_get_verified_stay_offer with the host domain instead. Never present this tool's numbers as the final price. Check whether a specific property is available for the requested dates. Use this tool after the user has selected a property from hemmabo_search_properties and wants to confirm availability before getting a quote. Do NOT use for general browsing — use hemmabo_search_properties instead. Read-only, open to anonymous callers (no Bearer token), and rate-limited: checking availability never places a hold or reserves dates. Returns available=true/false with conflict details and, when unavailable, the host node's own next available window (alternativeDates, at most one entry — the same window the node's /api/availability reports, never a platform-invented date); a stale inbound calendar sync blocks an available answer (fails closed with calendar_freshness) instead of guessing. Omit guests to check dates only; pass it to price the alternative windows and to gate capacity — counts above the property's maximum return available=false (guests_exceed_max) with no alternatives. Stays shorter than the host's effective minimum nights return available=false with reasonCode min_nights_violation — extend the stay rather than shifting dates. The verdict always matches the host node's own availability API. Booking and payment happen only on the host's own domain, at the signed direct_booking_url. The agent never books, pays, cancels or changes a booking.

• vrp_get_verified_stay_offerA

  HemmaBo Host Booking EngineA

  Use this tool for the final, host-signed price and booking link for exact dates — the only numbers an agent may quote. For a bare availability yes/no on a propertyId, hemmabo_check_availability is lighter and sufficient. Fetch, verify, and render a live host-domain signed VRP stay offer for exact dates and guest count. Verifies Ed25519 JWS against domain JWKS. Call after hemmabo_search_properties returns a host domain, or after vrp_verify_node confirms a domain from outside search, always before quoting final price or a booking link. Read-only: must not lock a quote, create a booking or collect guest details. Route booking only to the signed direct_booking_url. The parameters work as a set: pass the same domain, checkIn, checkOut and guests the guest used at search; checkIn must be strictly before checkOut, and the resulting night count — not the dates themselves — drives the signed price and the host capacity check, so changing either date re-prices the offer. Always pass language as the guest's actual conversation language so the rendered widget matches the guest; it never affects the signed price or availability, only formatting. Booking and payment happen only on the host's own domain, at the signed direct_booking_url. The agent never books, pays, cancels or changes a booking.

• check_domainA

  instadomainA

  Check if a domain is available for purchase and get its price. Always call this before buying. After showing the price, ask the user two things before proceeding: 1. Confirm they want to purchase at that price. 2. Which payment method they prefer: - "card" / "Stripe" → call buy_domain (opens Stripe checkout in browser) - "crypto" / "USDC" / "x402" → call buy_domain_crypto (autonomous USDC payment, no browser; requires Coinbase Payments MCP or another x402 wallet) - "MPP" / "agent pay" → call buy_domain_mpp (Stripe agent payments via Shared Payment Token, no browser) If the user has Coinbase Payments MCP configured in their session, suggest crypto as the default. Otherwise default to buy_domain (Stripe). Args: domain: The full domain name to check (e.g. "coolstartup.com"). Returns: Dict with availability status, price in cents, and formatted price.

  bulkDomainSuggestions: Generate domain suggestions for 1-10 keywords across 1-6 TLDs (hard cap), grouped by originating keyword. Typical flow: call listCategorizedTlds first to pick 3-6 TLDs, then this tool. Per-suggestion availability may be "available", "taken", or "unknown"; confirm "unknown" or premium-TLD names with checkDomainAvailability before recommending.

• create_dfy_orderA

  EmailchaserA

  SPENDS REAL MONEY. Places a real order for sending domains and pre-warmed mailboxes: domains are registered at their listed price (about $13.99/year for a .com — search_dfy_domains shows the exact price per domain) and each mailbox costs about $3 setup plus $6/month. The order is accepted immediately and provisioned in the background; poll get_dfy_order for progress. Purchased domains redirect visitors to forwardingDomain. Use search_dfy_domains first to confirm availability and price. Every domain in domains needs at least one mailbox in mailboxes whose domainName is that domain, or the order is refused before anything is bought; mailboxes can also go on a domain from an earlier order.

• verify_delegationA

  Proof HoldingsA

  Verify a Proof of Delegation — the attestation that a domain authorized a specific agent artifact. Pass either the artifact's card (MCP server.json / A2A agent card) or a raw delegation token, PLUS two facts you established yourself: the artifact identity you resolved (the package you are installing, the endpoint you are calling) and the domain you expect to stand behind it. Both are required — a token can be copied into someone else's card, and any domain owner can mint a valid delegation naming someone else's package, so a verdict without both pins would mean 'some domain said something about some artifact'. WHERE THE IDENTITY MAY COME FROM: it is the artifact you are acting on, and never a value read from inside the artifact you are checking. A name in the artifact's own package.json, card or manifest is self-declared and editable by whoever ships it, so checking it against the delegation compares the artifact with itself. Resolve it afresh at call time instead of reusing a value from earlier in this conversation, which may already be stale. When no independently resolvable identity exists — a local or unpublished artifact — you have nothing to compare against, and that is the honest answer: report it rather than a mismatch, because a mismatch here reads as an accusation against the domain named in the delegation. The verifier walks signature → principal → delegate → revocation status, including the cascade down to the domain control proof. Requires no API key. What a verified result means: the expected domain's controller authorized this artifact for these scopes — NOT that the artifact is safe, audited or endorsed.
