# Bareun MCP Server — Korean NLP & Spell/Grammar Checking[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](./LICENSE)[![smithery badge](https://smithery.ai/badge/gih2yun/bareunai)](https://smithery.ai/servers/gih2yun/bareunai)> **바른(Bareun)** is a Korean natural-language platform. This is its **MCP (Model> Context Protocol)** server — it lets any MCP-compatible AI tool (Claude, Cursor,> VS Code, Claude Desktop, ...) perform **Korean morphological analysis** and> **spell/grammar correction** by calling Bareun as a tool.Large language models still miss the subtle spacing, particle agreement, andconfusable-word rules of Korean. Plug Bareun in as an MCP tool and your agent canhand off analysis and proofreading to a dedicated Korean engine, then use theresult to produce more accurate Korean output.- **Hosted endpoint:** `https://api.bareun.ai/mcp`- **Transport:** Streamable HTTP (JSON-RPC 2.0) — no SSE, no extra port, no install- **Auth:** API key (`api-key` header or `Authorization: Bearer <key>`)- **Get an API key:** https://bareun.ai> The `/mcp` endpoint is available on the **spell-checker–included** build of Bareun> (the morphological-analysis-only build does not expose `/mcp`). The same endpoint> works on self-hosted/on-prem installs — just swap the host.---## What it looks like**Spelling & spacing — `correct_grammar`** (real output from `https://api.bareun.ai/mcp`):| | ||---|---|| **In** | 회의결과를 정리해서 내일까지 보내주시기 바람니다. || **Out** | 회의 결과를 정리해서 내일까지 보내 주시기 바랍니다. |Every fix comes back as a block, so an agent can explain the edit instead of silentlyrewriting the sentence:| Original | Corrected | Category | Rule ||---|---|---|---|| 회의결과를 | 회의 결과를 | `SPACING` | compound noun spacing || 보내주시기 | 보내 주시기 | `SPACING` | auxiliary-verb spacing || 바람니다. | 바랍니다. | `TYPO` | misspelling |**Morphological analysis — `analyze_syntax`** (`format: compact`):| | ||---|---|| **In** | 나는 학교에 간다. || **Out** | `나/NP 는/JX 학교/NNG 에/JKB 가/VV ᄂ다/EF ./SF` |**Homograph senses —
