AIsa Technologies & WhoisBOAuth

one.aisa

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.
