# Numeral Formatter Engine MCP for AI Agents AI Agent Connect > Numeral Formatter Engine turns raw numbers into clean, readable strings like $10,000.00, 2.5MB, or 97%. It stops your AI from guessing how to format currency, percentages, or file sizes, ensuring your reports and dashboards always look professional. Use it to maintain consistency across every dashboard, financial summary, and data visualization project without manual editing. ## Overview - **Category:** productivity - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_rVLKCpu0QlF17aqsYm1RFEw8jnTfj9X87Xo8yPQ8/ai-agent-connect - **Tags:** data-formatting, localization, currency-formatting, data-visualization, deterministic-output, number-parsing ## Description When you ask an AI agent to build a financial summary or a data dashboard, the results often look messy because the model doesn't know how to handle numbers properly. It might show 10000 instead of $10,000.00 or fail to convert bytes into a readable format like 2.5MB. This Connector fixes that by handling all the heavy lifting of number formatting. You'll get consistent results every time, whether you're dealing with complex percentages or simple abbreviations. It's a reliable way to make sure your data looks exactly how you want it to appear on a screen or in a printed report. Instead of having to manually check every single digit or asking the agent to try again, you can set specific patterns for your currency, file sizes, and percentages. This ensures that every piece of data follows your brand guidelines and remains easy for your users to read. You can easily connect this to your existing setup through the Vinkius catalog to give your agent a dedicated tool for perfect data presentation. It takes the guesswork out of the equation so you can focus on the actual insights rather than the punctuation. It's the difference between a raw data dump and a polished, professional presentation. ## Tools ### format_numeral Converts a raw number string into a specific display format like currency or bytes. It handles the logic for symbols and decimals automatically. ## Prompt Examples **Prompt:** ``` Format 50000 as a US dollar amount. ``` **Response:** ``` Formatted Number: **$50,000.00** ``` **Prompt:** ``` Show 2560000 as a human-readable byte size. ``` **Response:** ``` Formatted Number: **2.5MB** ``` **Prompt:** ``` Display 0.973 as a percentage. ``` **Response:** ``` Formatted Number: **97%** ``` ## Capabilities ### Format currency values with symbols and decimals Converts raw numbers into standard currency strings like $10,000.00. ### Convert raw bytes into human-readable file sizes Turns large byte counts into readable units like 2.5MB or 1.2GB. ### Turn decimals into clean percentage strings Converts raw floats into clean percentages like 97%. ### Create short abbreviations for large numbers Formats large integers into readable abbreviations like 1.5k. ### Apply custom patterns to any numeric input Allows you to define specific display rules for any numeric data. ## Use Cases ### Summarizing a project budget A user asks the agent to summarize a $50,000 project budget. Instead of the agent outputting '50000', it uses format_numeral with a currency pattern to display '$50,000.00' in the final report. ### Displaying file sizes on a dashboard A developer wants to display file sizes on a dashboard. The agent takes a raw byte count of 2560000 and uses the Connector to convert it into '2.5MB', making the UI much cleaner for the end user. ### Reporting growth rates A financial analyst needs to show a 0.973 growth rate in a summary. The agent uses the Connector to turn that raw decimal into a clean '97%' string, ensuring the report looks professional. ### Shortening user counts A marketing manager wants to show a user count of 1,500 but prefers a shorter style. The agent uses the abbreviation pattern to display it as '1.5k' in the summary table. ## Benefits - Stop AI hallucinations by using Numeral.js for deterministic number display in every report. This ensures that your financial data stays accurate and consistent across all pages. - Get consistent currency symbols and decimal places with the format_numeral tool. You can define exactly how your money should look, whether it's US dollars, Euros, or something else. - Display file sizes in MB or GB automatically so your users can actually read them. The agent will handle the math to convert raw bytes into human-friendly units like 2.5MB or 1.2GB. - Turn messy decimals into clean percentages without worrying about rounding errors. Your agent will take a raw float and output a clean percentage string like 97% every single time. - Save time on manual data cleaning by letting the agent handle the formatting logic. You won't have to go into your source data to fix punctuation or symbols before presenting it to others. ## How It Works The bottom line is that your AI stops guessing and starts producing professional, production-ready numbers. 1. Provide the raw number and the desired format pattern to the AI. 2. The Connector processes the input using the Numeral.js library. 3. You receive a perfectly formatted string ready for display. ## Frequently Asked Questions **How does the Numeral Formatter Engine help with my financial reports?** It ensures every dollar amount, percentage, and large number is formatted consistently.
