## Research notes
Added 2026-08-25 in the coverage sweep. 21 tools across three groups: Web Metrics (16 tools covering traffic, referrals, similar sites, demographics, technology detection), Search Metrics (2 tools for SERP and keyword click trends), App Metrics (3 tools for install penetration, store rankings, app details). IMPORTANT COST MECHANIC, and the sharpest practical warning in this file: MCP calls consume the same data credits as regular API calls, and consumption varies with query complexity, so an agent looping over an account list can burn a credit budget fast with no natural stopping point. api_gate is enterprise-only despite a naming quirk worth explaining: the developer docs say MCP requires a subscription on the "API-only, Business, or Enterprise" plans with API access enabled, but Similarweb's corporate pricing page publishes no prices at all, splits into self-service "Entrepreneurs" packages versus sales-contact "Businesses and Enterprises," and its FAQ states plainly that "API is available as part of our customized packages for Businesses." So the "API-only" plan has no published price and no self-serve path. BEWARE the Apify "Similarweb scraper" MCP servers in search results; those are third-party scrapers, one explicitly marked DEPRECATED, and are not Similarweb.
