Your agent needs to know how big a website really is — traffic, where it comes from, who else the audience visits, what they pay for ads, and which rivals take the same demand. **What you can ask for** • "How much traffic does this domain get, and how has it trended?" • "Where does that traffic come from — search, referral, social, paid?" • "Who else does this audience visit, and where do we overlap?" • "What keywords send them traffic, and which landing pages receive it?" • "What do they spend on ads, and on which networks?" **How to use it** Point any MCP client at https://mcp.aisa.one/similarweb/mcp and sign in with OAuth — there is no key to create or paste. 23 tools: traffic snapshot, trend and engagement, ranking and top sites, marketing channels and referrals, keywords and landing pages, popular pages and subdomains, demographics, audience interest and overlap, deduplicated audience, ad networks, PPC spend, technologies, similar sites and SERP players. **Why this rather than the source** A competitor's numbers without asking them, and without a seat in an enterprise dashboard. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Size the competitor here, then ask the same agent who links to them or who to contact there — 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 to turn the finding into contacts; https://mcp.aisa.one/seo/mcp for the ranking side.
