Real-time Google Flights fares for agents. Three things people do with this server. Scan for deals: one call takes a date range and a list of destination airports, expands every combination server side, and returns each fare with Google's own low, typical or high verdict. Put live search in your app: flat JSON with a bookable link on every result, and round trips priced as paired legs. Run a 24/7 AI travel agent: add the server, sign in with Google, and schedule it. No ads, no sponsored content. You bring your own RapidAPI key, so every search is billed to your plan and never to anyone else's. Add https://flights.flightpowers.com/mcp , click Sign in, sign in with Google, and paste your RapidAPI key once on the page that opens. Scripts and clients without a sign-in button send the key as x-rapidapi-key on the same URL.

Works anonymously with no signup, or sign in for permanent docs under your own handle.

Your agent needs marketplace data — what a product costs on Amazon and Google Shopping, who the sellers are, what reviewers actually complain about. **What you can ask for** • "What is this ASIN's price history, rating and seller list?" • "Who else sells this product, and at what price?" • "Pull the reviews for this product and group the complaints." • "What comes up on Google Shopping for this query in the UK?" • "Compare these products across both marketplaces." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-merchant/mcp and sign in with OAuth — there is no key to create or paste. 22 tools: Amazon products, ASIN detail and sellers; Google Shopping products, product info, sellers and reviews; live and queued forms, with raw HTML where you need it. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Price the product here, then ask the same agent what the brand's site traffic or ad spend looks like — 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.
