# Twitter/X Character & TCO MCP for AI Agents MCP > Twitter/X Post Character & TCO Calculator helps you figure out exactly how much space your content takes up before you hit post. It handles the tricky stuff like how URLs get shortened to platform-specific links, how complex emojis count against your limit, and how images don't count at all. It is perfect for making sure your high-impact posts actually fit within the platform's constraints without you having to do the math manually. ## Overview - **Category:** productivity - **Price:** Free - **Endpoint:** https://edge.vinkius.com/undefined/mcp - **Tags:** twitter, x, character-count, url-shortener, emoji ## Description This MCP helps you manage the constant game of tetris that is writing for Twitter/X. You want to pack in the most information possible while keeping it readable, but the platform's character limits are notoriously finicky. A single link can eat up a huge chunk of your space, and some emojis count for way more than they look like they do on your screen. This tool takes the guesswork out of content planning by giving your AI client the ability to see the true cost of every character, link, and image you include. It handles the specific logic of platform-shortened link wrapping and multi-codepoint emoji weighting so you don't have to. It is a handy addition to the Vinkius catalog for anyone who needs to maintain a consistent brand voice while maximizing every available character. You get to focus on the messaging while the tool ensures the technical constraints of the platform are met perfectly every time. Instead of squinting at a character counter and wondering why your post got cut off, you can have your agent verify the exact footprint of a draft before it goes live. This is especially useful for high-volume accounts where a single character overage can ruin a scheduled campaign. ## Prompt Examples **Prompt:** ``` How much space is left in this tweet: 'Hello world! https://vinkius.com/blog/post'? ``` **Response:** ``` Based on the Twitter/X rules, here is your character breakdown: - **Current Text:** 12 characters - **URL Weight:** 23 characters (platform-shortened) - **Remaining Budget:** 257 characters You are well under the limit! ``` **Prompt:** ``` Calculate the character weight of: 'Check this out! 🚀' ``` **Response:** ``` Here is the weight for that post: - **Text:** 15 characters - **Emoji Weight:** 1 character (complex codepoint) - **Total Weight:** 16 characters ``` **Prompt:** ``` Summarize how much space I saved with links in: 'Link 1: https://vinkius.com/a Link 2: https://vinkius.com/b' ``` **Response:** ``` By using these links, you have optimized your character count: - **Original Space:** 92 characters - **Compressed Space:** 46 characters - **Total Saved:** 46 characters This gives you more room for your call to action. ``` ## Capabilities ### Calculate exact tweet length Get the real character count for any draft including hidden weights. ### Check URL compression See how much space you save when links are converted to platform-shortened versions. ### Analyze emoji weight Find out how many characters a complex emoji actually consumes. ### Verify media neutrality Confirm that images and videos are not counting against your character limit. ### Audit remaining budget See exactly how many characters you have left after adding content. ## Use Cases ### Verifying long URLs A social media manager wants to know if a long URL will break their tweet.

The agent verifies the total footprint of the draft. ## Benefits - Stop worrying about character limits by using calculate_post_metrics to get a definitive count of your draft before posting. - Maximize your message space by using summarize_url_compression to see exactly how much room you save with platform-shortened links. - Avoid hidden character costs from complex emojis by letting the MCP calculate their true weight automatically. - Plan complex multi-tweet threads with confidence by checking the exact footprint of each individual post. - Ensure your call to action always fits by checking your remaining budget before finalizing your social media copy. ## How It Works The bottom line is you get a precise character count for Twitter/X posts that accounts for all platform-specific rules. 1.
