Bareun (바른) — Korean NLP & Spell Checking

Bareun (바른) is a Korean natural-language engine. This MCP server lets any MCP-compatible client hand Korean text to a dedicated Korean engine instead of guessing: analyze_syntax (morphological analysis with 47 POS tags and beta homograph sense disambiguation), analyze_syntax_raw (raw model output, no post-processing), tokenize, correct_grammar (spelling and spacing correction with per-edit blocks and rule categories), and list_pos_tags. Resources expose the POS tag table, server info, and the custom dictionaries registered for your key. Hosted at https://api.bareun.ai/mcp over Streamable HTTP — nothing to install. Authenticate with an api-key header (get a free key at https://bareun.ai). The same endpoint ships with self-hosted/on-prem Bareun installs.
