AI Proofreads Your Official Documents — Without Sending Them Anywhere

GongMun Doctor MCP — 100% local Korean official document proofreading & generation. Free and open source.

📅 April 2026 ✍️ 22B Labs ⏱ 5 min read

Anyone who writes Korean official documents, business reports, or inter-department correspondence knows this problem. After drafting, you want to double-check spelling and formal style — but generic spell-checkers don't know Korean official document conventions. Asking a colleague every time isn't ideal either.

GongMun Doctor MCP connects to Claude or Codex to automate proofreading and document generation. Say "proofread this document" and three correction layers apply automatically: spelling, grammar, and official document style. It's built for anyone who writes in Korean official document format — government staff, public institution employees, corporate teams, administrative professionals, and beginners.

"Korean official documents have their own grammar rules.
GongMun Doctor corrects what generic spell-checkers miss.
Just connect to Claude or Codex and talk."

📌 Note — When proofreading, document content is sent to the connected AI service (Claude, Codex, etc.). For sensitive documents, check the privacy policy of the AI service you use.

correction layers

3-Layer Correction Rules

This is different from a general spell-checker. Korean official documents have their own grammar. Three layers apply in sequence.

L1 · SPELLING

Spacing & Spelling

General + official document compound word rules

"시행알림" → "시행 알림"

L2 · GRAMMAR

Particle Errors

Official docs prohibit dual-particle notation

"을/를" → "을"

L3 · OFFICIAL STYLE

Administrative Manual

Corrections per official document style guide

"관련하여," → "관련하여"

faq

FAQ

Q: The server starts but document correction doesn't work.

Actual .hwpx correction requires the python-hwpx runtime. Run: pip install "python-hwpx>=2.8.0"

Q: Do documents get sent to an AI server?

No. In default mode, documents never leave your PC. All corrections run locally. Cloud LLM analysis is an opt-in extension.

Q: Does it support .hwp (older format)?

Yes, both .hwpx and .hwp are supported.

Q: Claude Desktop connection doesn't work.

Primary support targets are Codex and Claude Code. Claude Desktop works via manual stdio — see examples/claude_desktop_config.json.
