One live capture, your best organic position, no rank-tracker subscription and no credits. ## TL;DR ToolPiper captures the live results page in your own Chrome and reports where a domain sits for a query, or null when it does not appear. It is a point sample with no stored history, which is the honest shape of a single check. Checking one rank should not require a monthly subscription and a seat. Most of the time the question is small: I changed a title last week, did it move? Rank trackers answer that by scheduling captures and storing history, which is genuinely more than a single check gives you. What follows is the single check, done well, on your own machine. ## What a rank check is, and what it is not A rank check captures a results page once and reports where a domain appears. That is a point sample. It is not a trend, it is not an average across locations, and it is not evidence on its own that a change worked. Start with what this does not do. There is no search volume here, no keyword difficulty, no cost per click, no backlink index, no domain overview, no stored rank history and no site crawler. If you need any of those, a vendor backed suite such as OpenSEO has them and ToolPiper does not. OpenSEO is open source under MIT with nine agent skills, and its data is metered through DataForSEO on every keyword, SERP and backlink call. Verified 2026-08-28. ## How ToolPiper does it `serp_rank_check` captures the SERP once through the same browser path as a full capture, then reports each requested domain's best organic position, or null when it does not appear in the top results. You can pass a bare host or a full URL; both are normalised, and www is stripped, before matching. Because it reads your own Chrome rather than a vendor feed, there is nothing to meter. The cost of the fiftieth check is the cost of the first. ## What you need macOS 26 or later on Apple Silicon, Google Chrome installed, ToolPiper, and an MCP client if you want your agent to run the check rather than you. ## Limits worth knowing before you start ToolPiper needs macOS 26 or later on Apple Silicon, and the SERP capture drives Google Chrome over the DevTools Protocol, so Chrome has to be installed. One capture is a sample, not a measurement: AI Overview presence rotates by session, location and personalisation, so a single run tells you what happened once, in your browser, from where you are sitting. Search Console tools sit behind Google OAuth on your own account. ## Try it Download ToolPiper and check one query you care about, then check it again after your next title change.

The roundup covers SERP capture, keyword discovery, rank checks, Search Console and listening in one place._ ## Steps ### 1. Install ToolPiper Download the signed DMG from [modelpiper.com/download](/download) and launch it. Chrome must be installed, because the capture drives it over the DevTools Protocol. ### 2. Name the query and the domains Ask for the check in plain language: "where does modelpiper.com rank for macos mcp server?" You can pass several domains at once to see your position and a competitor's from the same capture, which removes the session-to-session variation between two separate checks. ### 3. Read null as null A domain that does not appear in the captured results returns null, not a large number. That distinction matters: null means "not in the top results of this capture," which is different from a measured position of 90. ### 4. Re-check after a change, and treat both as samples Capture before you edit a title, then again after it is indexed. Two point samples are a weak signal on their own, so look for a move large enough to survive the rotation you would see by capturing twice on the same day. ## FAQ ### Does it store rank history? No. Each call is one capture with no stored series. A scheduled tracker with history is exactly what a vendor backed suite gives you and this does not. ### Why did my position change between two checks minutes apart? Results rotate by session, location and personalisation. That is a property of live search, not a fault in the capture, and it is the reason one sample is not a measurement. ### Can I check Bing as well as Google? Yes. The capture supports both. The AI Overview is a Google surface, so that part of the result is Google only. ### Does it check ranks for keywords I do not already know? No, this tool takes a query you name. To find queries, expand a seed with autocomplete, or read what you already rank for in Search Console.
