# LinkedIn Hook Truncation Analyzer MCP for AI Agents MCP > LinkedIn Hook Truncation Analyzer helps you figure out if your LinkedIn posts will get cut off before people can read them. It checks character counts and pixel widths for different devices, identifies your hook style, and gives you a score on how likely it is to stop someone from scrolling. ## Overview - **Category:** social-media - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_mvJI1qh2xMBKY7wH0SIUuItUznm91tZ8OOfOSSTZ/mcp - **Tags:** linkedin, copywriting, engagement, truncation, hook-analysis ## Description You're putting hours into a LinkedIn post only for the most important part to get buried behind a "See more" button. This tool fixes that by giving your AI client the data it needs to judge your copy before you hit publish. It looks at how text actually wraps on a phone screen versus a desktop, so you know exactly where that cutoff happens. It also categorizes your opening lines, whether they're stats, questions, or lists, to make sure you're hitting the right notes for your audience. Instead of guessing if a hook is punchy enough, you get a score based on the rhythm and punctuation of your writing. It's a way to move from "I think this looks good" to "I know this works." You can find this and thousands of other tools in the Vinkius catalog to keep your content strategy sharp. ## Tools ### analyze_truncation_metrics Tells you if your hook will be visible on specific devices and calculates formatting density. This helps you avoid hidden content. ### evaluate_scroll_stopper_score Gives you a numerical score for how well your hook grabs attention based on rhythm. Use it to quantify your copy's impact. ### identify_hook_classification Categorizes your opening line into types like Question, Statistic, or Listicle. This helps you diversify your content style. ## Prompt Examples **Prompt:** ``` Will this hook get cut off on a phone? 'Stop wasting time on manual outreach. It is killing your productivity and costing you thousands in lost revenue every single month.' ``` **Response:** ``` The post exceeds the 150-character mobile limit. **Visible text:** 'Stop wasting time on manual outreach. It is killing your productivity and costing you thousands in lost...' **Status:** Truncated **Recommendation:** Shorten the opening by about 20 characters to ensure the full hook is visible. ``` **Prompt:** ``` What kind of hook is this: 'Did you know that 85% of LinkedIn users scroll past posts without reading the first line?' ``` **Response:** ``` This is a **Statistic** hook. **Analysis:** * **Type:** Statistic * **Confidence:** High * **Reason:** The hook leads with a specific numerical data point (85%) to establish authority and grab attention. ``` **Prompt:** ``` Is this hook punchy enough? 'I used to hate cold calling. Then I found a system that changed everything.' ``` **Response:** ``` Here is the engagement potential for that hook: **Scroll-Stopper Score:** 78/100 **Breakdown:** * **Rhythm:** Good. The use of short sentence fragments creates a nice pace. * **Punctuation Variance:** High. The period placement helps with readability. * **Impact:** Strong, but could be improved by adding a specific result. ``` ## Capabilities ### Check mobile and desktop visibility limits See exactly where your text will break on different devices. ### Identify the specific type of hook used Categorize your opening lines into styles like stats or lists. ### Get a score on scroll-stopping potential Receive a numerical rating for your hook's engagement power. ### Measure character and pixel density Get precise data on how much content fits in the initial view. ### Detect punctuation patterns in hooks Analyze the rhythm and variance of your punctuation. ## Use Cases ### Mobile Optimization Check A creator wants to know if their 200-character hook is too long for an iPhone. They ask the agent to check visibility and get a specific character count. ### A/B Testing Hook Styles A marketer wants to compare two different hook styles, like a Question versus a Statistic, for the same post to see which scores higher. ### Batch Content Audit An agency is drafting 30 posts at once and needs to verify every single one for truncation using analyze_truncation_metrics. ### Style Variation Audit A brand wants to see if their recent posts are too repetitive in terms of hook types and uses identify_hook_classification to check. ## Benefits - Stop guessing about mobile cutoffs.
