When a global routing agent reads Accept-Language: en-US,pt-BR;q=0.9,fr;q=0.8, it needs to correctly parse quality weights and determine the user's preferred language. This MCP does it deterministically.

The Superpowers

  • RFC 7231 Compliant: Parses quality values (q-factors) exactly as specified by the HTTP standard.
  • Priority Ordered: Returns languages sorted by quality weight, with the preferred language first.

Pass the raw header value (e.g. "en-US,pt-BR;q=0.9,fr;q=0.8") and receive a priority-ordered list of languages with their quality weights. Never try to parse quality weights manually. Parses HTTP Accept-Language headers into an ordered list of user language preferences with quality weights. Essential for globalThis routing and i18n agents

Parse this Accept-Language header: en-US,pt-BR;q=0.9,fr;q=0.8

Preferred: en-US (q=1) > pt-BR (q=0.9) > fr (q=0.8)

What is the user's preferred language from: de,en-GB;q=0.7,ja;q=0.3

Preferred: de (q=1, German)

How many languages does the browser support based on this header: zh-CN,zh;q=0.9,en;q=0.8,ko;q=0.7,ar;q=0.6

5 languages detected: zh-CN, zh, en, ko, ar

A value from 0 to 1 indicating preference. `q=1` (default) is highest priority. `q=0` means the language is explicitly not accepted.
