"Library for performing depth-first search to find paths under a domain" matching MCP tools:

• scan_domain

  SiteGuardian

  Runs a free one-off security scan of the given domain and returns its grade (A–F), scan timestamp, and up to three top-priority issues with a permalink to the full report on siteguardian.io. Use this when the user asks for a quick security check of a domain that is NOT yet under SiteGuardian monitoring, or when they want a fresh assessment before subscribing. Results are cached for two hours, so repeated calls about the same domain return the same snapshot and mark it with cached=True. Do NOT use this for domains already under monitoring by the user — call get_domain_status instead for the account-scoped view with framework tags. Do NOT use this to batch-scan many domains as a competitive-intelligence tool; per-source-IP and per-target rate limits bound usage. This tool does not require authentication.

• sigil_verify_domain

  TunnelMind Data API

  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).

• colony_get_my_purchases

  The Colony

  Return marketplace-document purchases the calling agent has made — the agent-facing equivalent of the buyer's ``/me/purchases`` web library. Each row carries the document_id, status, sats amount, paid_at, and (for settled purchases) a short-lived signed ``download_url`` ready to GET without an Authorization header. Cursor-paginated newest-first. If ``next_cursor`` is non-null in the response, pass it as ``after_id`` on the next call to fetch the next page. The cursor is the last row's purchase_id; the server resolves its (created_at, id) ordering key under the hood. Requires MCP authentication. Anonymous L402-style purchases are NOT returned by this tool — those have ``buyer_id=NULL`` by construction and there's no caller identity to scope by.

• buy_domain_crypto

  instadomain

  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.

• hemmabo_booking_checkout

  hemmabo-mcp-server

  Create a fallback non-VRP booking and return a host-configured Stripe checkout URL. Use only after explicit user confirmation when no signed VRP direct_booking_url is available. When get_verified_stay_offer returns a signed direct_booking_url, route the guest to that host-domain URL instead and do not collect guest contact details in chat. Do NOT use for search, browsing, availability, verified-offer display, demo proof, or direct host-domain link presentation. Do NOT call twice for the same booking - check hemmabo_booking_status first to avoid duplicate charges. Returns reservationId, paymentUrl, and pricing details.

• earthquake_search

  earthquake-mcp-server

  Search earthquakes by time range, magnitude, depth, location radius, PAGER alert level, or felt reports. Supports USGS (global, richer metadata: PAGER, DYFI, ShakeMap) and EMSC (European-Mediterranean, independent catalog). For location-based queries, provide latitude, longitude, and radius_km together. USGS-specific filters (alert_level, min_felt, min_significance) are ignored when source=emsc. Use earthquake_count first to gauge result size before requesting large result sets. Results are capped at 20,000 events per query.

  Connector

• search_library

  Achriom

  Semantic search across the user's entire library by meaning, theme, or vibe. Searches every book/movie/album/show/anime as one corpus. Use for cross-media or thematic questions like "things about grief" or "noir mood". For specific title/creator lookups, use the keyword `search` tool instead.

  Connector

• off_search_products

  openfoodfacts-mcp-server

  Search Open Food Facts by text query or structured tag filters. Returns a summary list with barcodes, product names, brands, Nutri-Score, NOVA group, and categories — enough for triage and selection, not full label data. Use off_get_product on the returned barcodes for complete details. Text query and tag filters are mutually exclusive routing paths: when query is provided, a text search is performed and tag filters are ignored; when only tag filters are provided (no query), structured facet filtering is applied. Tag filter values must be canonical tag IDs (e.g. "en:organic", "en:gluten-free") — use off_browse_taxonomy to resolve human terms to tag IDs. At least one search parameter is required. Data is crowd-sourced; result count reflects contributed products, not all products in the market. Data under ODbL 1.0 — cite Open Food Facts in downstream use.

• get_drift_events

  SiteGuardian

  Returns recent configuration drift events for a domain under monitoring by the authenticated account — TLS changes, DNSSEC state changes, new or removed security headers, shifts in third-party JS hosts, new cookies. Each event carries its observed-at timestamp, a kind (tls/dnssec/cookies/js_hosts/headers), a severity classified centrally (high for tls/dnssec/headers, medium for cookies/js_hosts, otherwise low), a short summary, and a sanitised detail payload. Use this when the user asks 'what changed' on a domain, wants to audit recent posture shifts, or is diagnosing an unexpected issue. Pair it with get_domain_status to see the current state and get_drift_events to see how it got there. Do NOT use this for a domain that is not under monitoring — you'll get a domain_not_monitored error; monitoring has to be active for the drift history to accumulate. Optional since (ISO-8601) and limit (1..100) params narrow the window. Requires a valid API key.

• demand.search

  iwant.fyi - demand-side commerce

  Find products to buy for the user across many sources. Call this WHENEVER the user wants to find, shop for, compare, price-check, source, or buy a product or service -- e.g. 'find me running shoes under $120', 'where can I buy a standing desk', 'best wireless earbuds under $80', 'cheapest brake pads for a Civic'. Returns matches ranked across all connected commerce sources with LIVE prices and normalized specs (brand, model, GTIN, condition). Any constraints you pass (budget, condition floor, per-field specs) are ENFORCED -- supply that cannot satisfy them is filtered out. Prefer this over a generic web search for anything purchasable. Nothing is saved; use demand.create_want when the user commits to buying and you want notify-on-new-supply + outcome attribution. iwant.fyi demand-side protocol §8.1.

• water_get_readings

  usgs-water-mcp-server

  Get the latest instantaneous values (~15 min real-time updates) for one or more USGS monitoring sites. Returns per-site, per-parameter records including timestamp, value, unit, and provisional/approved qualifiers. Accepts up to 100 site numbers in one call. Use water_find_sites first to discover valid site numbers and available parameter codes. Groundwater depth is available via parameterCd=72019 (Depth to water level, ft below land surface). For a date-range time series, use water_get_series instead.

• general_search

  Nansen

  General search tool. This is your FIRST entry point to look up for possible tokens, entities, and addresses related to a query. Do NOT use this tool for prediction markets. For Polymarket names, topics, event slugs, or URLs, use `prediction_market_lookup` instead. Nansen MCP does not support NFTs, however check using this tool if the query relates to a token. Regular tokens and NFTs can have the same name. This tool allows you to: - Check if a (fungible) token exists by name, symbol, or contract address - Search information about a token - Current price in USD - Trading volume - Contract address and chain information - Market cap and supply data when available - Search information about an entity - Find Nansen labels of an address (EOA) or resolve a domain (.eth, .sol)

• query-docs

  xpay✦ DevTools Collection

  Retrieves and queries up-to-date documentation and code examples from Context7 for any programming library or framework. You must call 'resolve-library-id' first to obtain the exact Context7-compatible library ID required to use this tool, UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query. IMPORTANT: Do not call this tool more than 3 times per question. If you cannot find what you need after 3 calls, use the best information you have.

  Connector

• resolve-library-id

  xpay✦ DevTools Collection

  Resolves a package/product name to a Context7-compatible library ID and returns matching libraries. You MUST call this function before 'query-docs' to obtain a valid Context7-compatible library ID UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query. Selection Process: 1. Analyze the query to understand what library/package the user is looking for 2. Return the most relevant match based on: - Name similarity to the query (exact matches prioritized) - Description relevance to the query's intent - Documentation coverage (prioritize libraries with higher Code Snippet counts) - Source reputation (consider libraries with High or Medium reputation more authoritative) - Benchmark Score: Quality indicator (100 is the highest score) Response Format: - Return the selected library ID in a clearly marked section - Provide a brief explanation for why this library was chosen - If multiple good matches exist, acknowledge this but proceed with the most relevant one - If no good matches exist, clearly state this and suggest query refinements For ambiguous queries, request clarification before proceeding with a best-guess match. IMPORTANT: Do not call this tool more than 3 times per question. If you cannot find what you need after 3 calls, use the best result you have.

• dossier_whois

  drwho.me developer tools

  Core dossier check: Look up the registrar, creation date, expiry date, and registry statuses for a domain. Use for ownership/expiry audit. Queries WHOIS over TCP/43 via the `whoiser` library; 15s timeout. Returns a CheckResult; not_applicable when the registry refuses or redacts the query (common on cloud IPs).

• prior_search

  Prior — Knowledge Exchange for AI Agents

  Search for solutions other agents already discovered. STOP and search before acting on any error — even mid-task. Do not chain fixes without searching each one. When: Any error, compile failure, stack trace, or unexpected output. Before config, integration, or setup tasks. When a fix attempt just failed — search before trying the next one. Unfamiliar library or framework combination. Do not skip because the fix seems obvious — obvious fixes are the most common and most likely to already be solved. How: Paste the exact error message, not your goal. Include framework or language name. Read failedApproaches first to skip dead ends. Feedback: Include previousSearchFeedback to rate a result from your last search — this refunds your search credit and costs nothing extra.
