Swiss company-register intelligence: new GmbHs by canton, shared addresses, UID history, SHAB text
Rattlesnakes By Mail is a public record of dated, sourced claims about AI crawlers and AI agents, including GPTBot, ClaudeBot, PerplexityBot, Googlebot, and Applebot. Each claim carries a verbatim quote from vendor documentation, a publication date, and an evidence URL. Five MCP tools cover crawler lookup, user agent identification, change history since a given date, free-text question matching against published claims, and token-gated correction notes.
Your agent needs the link graph — who points at a competitor, what anchor text they use, what was won or lost last month, and which sites link to all of your rivals but not to you. **What you can ask for** • "Who links to my competitor and not to me?" • "What anchors point at this domain, and how spammy are the sources?" • "Which links did this site win and lose in the last 30 days?" • "Compare the referring domains of these five competitors." • "Summarise the backlink profile of these 100 domains in bulk." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-backlinks/mcp and sign in with OAuth — there is no key to create or paste. 27 tools: backlinks and referring domains, anchors, new and lost links over time, domain and page intersections, referring networks, spam scores, bulk summaries for many domains at once, plus Semrush's own backlink and indexed-page sets. **Why this rather than the source** Two independent link indexes behind one account — coverage differs, and the gap is usually the interesting part. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the link gap here, then ask the same agent who runs those sites and how to reach them — 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.
