What is the Numeral Formatter Engine MCP Server?
When an AI Agent builds a dashboard summary or writes a financial report, it shouldn't guess how to format 10000 as $10,000.00 or 2560000 as 2.5MB. LLMs frequently hallucinate locale-specific separators, currency symbols, and decimal precision.
The Superpowers
- Pixel-Perfect Formatting: Uses Numeral.js (6M+ weekly downloads) for strict, deterministic number display.
- Every Format Covered: Currencies (
$0,0.00), bytes (0.0b), percentages (0%), abbreviations (0.0a), and custom patterns.
Built-in capabilities (1)
Pass the raw number as a string and the Numeral.js format pattern (e.g. "$0,0.00" for currency, "0.0b" for bytes, "0%" for percentage, "0.0a" for abbreviations). Formats raw numbers into perfect display strings: currencies ($10,000.00), bytes (2.5MB), percentages (97%), or abbreviations (1.5k). Powered by Numeral.js
