Live US diesel prices and optimized stop-by-stop fuel plans for trucking. Free snapshot tool.
Your agent needs what customers say in public — Google Business profiles and reviews, Trustpilot, Tripadvisor, hotel listings and the Q&A under a listing. **What you can ask for** • "Pull this business's Google reviews and group the complaints." • "What do Trustpilot reviewers say about this competitor?" • "Find hotels matching this search and their live prices." • "What questions are people asking on this Google listing, and are they answered?" • "Search listings for this category in this city." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-business/mcp and sign in with OAuth — there is no key to create or paste. 22 tools: Google Business info, reviews, extended reviews, updates and Q&A; Trustpilot and Tripadvisor search and reviews; Google hotel info and searches; business listing search; plus Reddit and Pinterest signals for a business. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Read the reviews here, then ask the same agent what that business ranks for or who links to it — 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.
