DialectOS Spanish Dialects MCP server

DialectOS is a helper for Spanish translation that understands that Spanish is not one single language. It can turn your text into Mexican, Argentinian, Colombian, Puerto Rican Spanish and about twenty other regional versions, and it can check an existing translation for mistakes. It is handy if you write docs, app text, or support replies for Spanish-speaking customers in different countries.

What this MCP server does

You ask your AI something like translate this paragraph into Mexican Spanish. Your AI passes that request to the DialectOS helper. The helper sends the text to a translation model you have set up, using DialectOS rules for the dialect you picked, and keeps your formatting like tables, links, and code blocks in place. Then it checks the result for problems like meaning that drifted or formality that does not match. You get the finished translation back in your chat, along with any warnings.
