Get a research grade Tranco popularity rank and trend for any company domain.
An MCP server that returns a research grade Tranco popularity rank and trend for any company domain. It wraps the Mamba Labs Website Traffic Rank Estimator actor on Apify and returns a Clay-ready flat JSON row to any MCP client.
Give it a company domain and it returns that domain's position on the public Tranco list, the date of that position, a band from top_1k through beyond_1m, and whether the domain has been rising, falling or stable over roughly forty daily observations. One flat row per company.
These are ranks, not traffic. A Tranco rank does not convert to visits, sessions or a monthly number, and this tool will never return a visit count. A lower rank number is better, so the trend is given in words rather than as a signed number. Most B2B domains are not on the list at all and return not_found, which is normal rather than disqualifying. Cloudflare Radar and Chrome UX Report are available as extra sources with your own free keys, and a source you did not supply a key for reports skipped rather than not_found, because nobody looked.
All of the lookup runs on Apify. This package is a thin client that calls the actor and hands back the result unchanged.
You need Node.js 18 or newer and an Apify account with an API token.
Add this to your Claude Desktop config:
{
"mcpServers": {
"mamba-website-traffic-rank-estimator": {
"command": "npx",
"args": ["-y", "@mambalabsdev/mcp-website-traffic-rank-estimator"],
"env": {
"APIFY_TOKEN": "your-apify-token"
}
}
}
}
Get your token at https://console.apify.com/account/integrations, paste it in, and restart Claude Desktop. The estimate_website_traffic_rank tool will be available.
company_domain (optional): bare company domain, for example stripe.com. This is the lookup key and the join key for every other actor in the fleet.company_name (optional): carried through to the output row for joining. Rank lookup is keyed on the domain alone, so the name does not change the answer.sources (optional): which rank sources to query. One of tranco, tranco_radar, tranco_crux or all. Tranco is free and needs no key. Cloudflare Radar and Chrome UX Report each need your own free key, and a source you did not supply a key for reports skipped rather than not found.includeTrend (optional): when true (the default) the rank history Tranco already returns is used to say whether the domain is rising, falling or stable. It costs nothing extra, because the history arrives in the same response.minRank (optional): one of none, 1000, 10000, 100000 or 1000000. It sets rank_meets_threshold on the row, so you can filter a list to established sites without writing the comparison yourself. It never drops a row and never changes the rank returned.cloudflareApiToken (optional): your own Cloudflare API token, free to create at dash.cloudflare.com. Used only when sources includes Radar.cruxApiKey (optional): your own Google API key with the Chrome UX Report API enabled, free at console.cloud.google.com. Used only when sources includes CrUX.skipCache (optional): when false (the default) a successful lookup is cached for seven days and reused. Set true to force a fresh fetch.The tool returns the actor's flat JSON row for the company, with 20 snake_case fields and no nested objects. tranco_rank comes with tranco_rank_date, because a rank without a date has no shelf life. rank_band gives an honest band rather than false precision, rank_trend is a word, and radar_status and crux_status say whether those sources ran. See the Apify Store page for the full output schema.

This server is one of the Mamba Labs GTM Suite MCP servers. Every actor in the suite takes a domain or a company and returns one flat row, so they stack in the same Clay table without reshaping anything. The actor behind this server is the Website Traffic Rank Estimator, immutable Apify actor ID GnOFUzlNVIoXgeJjH.
