Bareun — Korean NLP & Spell/Grammar Checking
Wire Korean morphological analysis and spell/grammar checking into Claude Code or Cursor so agents proofread and structure Korean copy instead of guessing spacing and particles.
Overview
Bareun is an MCP server for the Grow phase that performs Korean morphological analysis and spell/grammar checking for AI coding agents.
What is this MCP server?
- Hosted Streamable HTTP MCP at https://api.bareun.ai/mcp—no local port or SSE setup
- Tools: analyze_syntax (morphological POS tagging) and spell/grammar correction via Bareun’s Korean engine
- Inputs include auto_split_sentence, auto_spacing, auto_jointing, and custom dictionary names
- API-key auth via api-key header or Authorization Bearer
- Spell-checker–included Bareun build required; morph-only builds do not expose /mcp
- Hosted MCP endpoint: https://api.bareun.ai/mcp
- Transport: Streamable HTTP, JSON-RPC 2.0 (no SSE)
- Documented tools include analyze_syntax and spell/grammar correction
What problem does it solve?
LLMs routinely break Korean spacing, particles, and easily confused words, which makes shipped copy look unprofessional even when the draft sounds fluent.
Who is it for?
Indie builders shipping Korean landing pages, docs, emails, or support content through Claude Code, Cursor, or Claude Desktop who want a dedicated Korean NLP backend.
Skip if: English-only products, teams that need non-Korean grammar tooling, or environments that cannot use outbound HTTPS to api.bareun.ai with an API key.
What do I get? / Deliverables
After you register the hosted MCP with a Bareun API key, agents can call analyze_syntax and proofreading tools and fold structured Korean linguistic results back into drafts and fixes.
- Tokenized/morpheme-level syntax analysis for Korean sentences
- Spell and grammar correction suggestions grounded in Bareun rules
- Agent-ready structured text you can loop into revised Korean copy
Recommended MCP Servers
Journey fit
Korean proofreading and linguistic structure land in Grow/Content when solo builders ship blogs, lifecycle emails, support macros, and localized product copy—not when they are still picking a niche. Content is where incorrect spacing, particle agreement, and confusable-word errors hurt credibility; Bareun tools target that output quality directly.
How it compares
Korean NLP MCP integration backed by Bareun’s engine—not a generic writing skill or English-only linter.
Common Questions / FAQ
Who is Bareun for?
Solo and indie builders using MCP agents to write or review Korean text who need morphological analysis and spell/grammar checks beyond what the model alone provides.
When should I use Bareun?
Use it while editing Korean marketing copy, documentation, UI strings, or customer-facing messages whenever spacing, morphology, or grammar must be validated before publish.
How do I add Bareun to my agent?
Obtain an API key at https://bareun.ai, add the remote MCP server URL https://api.bareun.ai/mcp in your client’s MCP settings, and send the key in the api-key header or Authorization Bearer as documented.
