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.
Fetch any public web page through managed proxies, with optional JS rendering and extraction rules.
Your agent needs the open web — searched by more than one engine, and read as clean markdown rather than raw HTML. **What you can ask for** • "Search this question with two providers and tell me where they disagree." • "Scrape these 40 URLs into markdown, in one batch." • "Crawl this documentation site and give me every page." • "Do deep research on this topic and cite the sources." • "Find the academic papers behind this claim." **How to use it** Point any MCP client at https://mcp.aisa.one/search/mcp and sign in with OAuth — there is no key to create or paste. 30 tools across several independent providers: Tavily and Exa search, answers, contents and agent runs; Firecrawl scrape, batch scrape, crawl, map and search; Perplexity Sonar, Sonar Pro, reasoning and deep research; Oxylabs AI search and LLM jobs; OpenAI and Anthropic web search; and scholarly search. **Why this rather than the source** Several independent indexes behind one account, because one engine's blind spot is not visible from inside it. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the page here, then ask the same agent who links to it or how much traffic it gets — 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/seo-serp/mcp for the Google results page itself, https://mcp.aisa.one/seo-serp-other-engines/mcp for Bing, Baidu and Naver.

Google is not the whole market. Your agent needs Bing, Yahoo, Baidu, Naver, Seznam and YouTube results — the engines that decide whether you exist in China, Korea, Japan or Central Europe. **What you can ask for** • "What ranks for this term on Baidu, and how different is it from Google?" • "Check Naver results for our Korean brand name." • "Compare Bing and Yahoo results for the same query." • "What comes up on YouTube search for this phrase in Japanese?" • "Take a screenshot of the results page as a user there sees it." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-serp-other-engines/mcp and sign in with OAuth — there is no key to create or paste. 34 tools: organic results from Bing, Yahoo, Baidu, Naver and Seznam in live, regular and raw-HTML forms, YouTube search, an AI summary of a result set, and a rendered screenshot. **Why this rather than the source** The engines that matter outside the US, with the same call shape as the Google ones. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Check the local engine here, then ask the same agent what the site's traffic or backlinks look like in that market — 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/seo-serp/mcp for Google itself. 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.
Your agent needs to crawl a site and say what is wrong with it — broken tags, duplicate content, pages nothing can index, resources that never load. **What you can ask for** • "Crawl this site and list every page with a duplicate title or missing description." • "Which pages are non-indexable, and why?" • "Run Lighthouse on these URLs and give me the failing audits." • "Show the internal link graph and the orphan pages." • "Give me this page's raw HTML and its microdata." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-onpage/mcp and sign in with OAuth — there is no key to create or paste. 20 tools: submit a crawl and read its summary, pages, resources, links and waterfall; duplicate content and duplicate tags; keyword density; non-indexable and uncrawlable resources; parsed content, raw HTML, microdata, screenshots and Lighthouse. **Why this rather than the source** A crawler you drive from the agent, with the audit results as structured data rather than a PDF. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the broken pages here, then ask the same agent what those pages used to rank for — 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/seo/mcp for all of it at once — rankings, keywords, backlinks, site health and AI-answer visibility across DataForSEO, Semrush and Ahrefs.

Your agent needs the Google results page as it actually renders — organic and paid, the AI overview, maps, images, news, jobs and the finance panel — not a scraped guess. **What you can ask for** • "What does the SERP for this keyword look like in Germany, on mobile?" • "Does this query trigger an AI overview, and what does it say?" • "Who is advertising against our brand name?" • "Find local results and the map pack for this phrase." • "Search Google by this image and tell me where else it appears." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-serp/mcp and sign in with OAuth — there is no key to create or paste. 38 tools across Google's surfaces: organic, ads and advertisers, AI mode, autocomplete, images, news, maps and local, events, jobs, datasets, scholar, finance quotes and markets, plus Semrush's organic and paid result sets. **Why this rather than the source** Location and language are parameters, so you can read the page a customer in another country sees. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Read the SERP here, then ask the same agent who links to the winner or how much traffic they get — 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/seo-serp-other-engines/mcp for Bing, Yahoo, Baidu, Naver, Seznam and YouTube. 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.
