GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Your agent needs to know what a site is built on and who owns it — or to find every site running a given technology. **What you can ask for** • "What is this site built on — CMS, analytics, payments, CDN?" • "Find every domain running Shopify in Germany." • "Who owns this domain, and when does it expire?" • "How many sites use this technology, and is that growing?" • "Find domains whose HTML contains this snippet." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-domains/mcp and sign in with OAuth — there is no key to create or paste. 12 tools: technology detection for one domain, domains by technology, domains by HTML term, technology stats and aggregations, plus whois overview and its filters. **Why this rather than the source** Prospecting by tech stack and ownership lookup in the same call shape. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the stack here, then ask the same agent for that company's traffic and the people to contact — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/sales/mcp turns a technology list into a contactable pipeline. https://mcp.aisa.one/seo/mcp for all of it at once — rankings, keywords, backlinks, site health and AI-answer visibility across DataForSEO, Semrush and Ahrefs.
Domain availability search, WHOIS lookup, TLD pricing and registry rules from name.ai. Read-only.
Claim a working subdomain in one call — A, CNAME and TXT records. No domain to buy, no account.
Free anonymous website, DNS, email and TLS checks, plus monitor read and opt-in write access.
Audits a sample of HTTP request URLs against explicit, documented cache-key standardization rules...
Buy and manage residential, mobile and datacenter proxies in 170+ countries, prepaid per GB
{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"whoami","arguments":{}}} free no key
Free owned-agent uptime monitoring, DNS domain proof, signed alerts and opt-in endpoint checks.
Calculates IPv4 subnet information from an IP address and CIDR prefix or dotted decimal subnet mask
If-None-Match star-or-etag, value discarded
DNS, WHOIS/RDAP, DMARC/SPF, LEI, sitemap, web extract, VAT, QR. Paid per call in USDC, no signup.
IPv4 or IPv6, address discarded
Scan the open TCP ports of your own public IP. Fast (32) or deep (65535). No key, no signup.
What's My IP Address: caller's public IP, ASN, geo, timezone, user-agent, headers, TLS info.
SIP/VoIP/telecom grounding for AI agents: vendor docs, RFCs, STIR/SHAKEN, traces, configs.
Site crawl + tech stack + DNS + SSL + WHOIS — five web-intel layers in one MCP.
Domain registration for AI agents via Stripe or x402 crypto with Cloudflare DNS.
The internet's largest queryable infrastructure graph — 7.39 billion nodes, 39 billion edges, 5.6 million threat-intelligence relationships. Pivot from any IP, domain, or ASN across DNS, BGP, WHOIS, GeoIP, and threat intel in a single Cypher query. Most threat-intel and OSINT APIs are point lookups: you ask about one indicator, you get one record. Investigations don't work that way — you start from one suspicious domain and need to trace its hosting, its sibling domains, its registrar, its email
Internet identity for AI agents: register or broker domains, email, DNS - pay by card or USDC.
Live demo of Frisian-MCP, a Django/DRF package that exposes ViewSets as MCP tools through grouped dispatchers — ~1,800 endpoints collapsed into ~16 tools, with DRF permission classes enforced in-process before ORM access. Connect to try the dispatcher pattern against a realistic network-automation surface.
