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."

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
"compound-word spacing example" -> "space the official notice term"
L2 · GRAMMAR
Particle Errors
Official docs prohibit dual-particle notation
"dual-particle placeholder" -> "single-particle form"
L3 · OFFICIAL STYLE
Administrative Manual
Corrections per official document style guide
"remove the trailing comma" -> "official-document form"

Getting Started

⚠️ Python 3.12 or 3.13 recommended — Python 3.14 may have lxml build issues.
# 1. Clone git clone https://github.com/sinmb79/GongMun-Doctor-MCP.git cd GongMun-Doctor-MCP # 2. Install dependencies python -m pip install "mcp[cli]>=1.0,<2" python -m pip install -e . --no-deps # 3. Install HWPX runtime (for actual document correction) python -m pip install "python-hwpx>=2.8.0"
💡 Connect via Codex (simplest)

codex mcp add gongmun-doctor -- python -m gongmun_doctor.mcp.server

💡 Connect via Claude Code

claude mcp add --transport stdio gongmun-doctor -- python -m gongmun_doctor.mcp.server
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.

GitHub's VS Code BYOK move matters more than it looks

-
Bring-your-own-key support can look like a small settings change until you view it through procurement, governance, and model volatility. GitHub's new BYOK option for Copilot Business and Enterprise users in VS Code signals a larger shift in developer tooling. Teams increasingly want the convenience of an integrated AI surface without surrendering model choice, billing control, or policy flexibility to a single vendor path. Three Things to Know GitHub now lets organizations use their own model-provider keys inside VS Code Chat and agent workflows, including built-in and custom agents. That matters because enterprise teams want portability across providers, cleaner cost accounting, and the option to use local or regional models. Viewed alongside GitHub's recent interaction-data policy update, BYOK also reads as a trust feature for organizations that care deeply about data boundaries.
