Introducing hwp-mcp: Korean document support for Claude via MCP

Korean office documents (.hwp / .hwpx) are everywhere in Korean government, enterprise, and legal workflows. Until now, Claude, ChatGPT, and Cursor couldn't read them natively — a real blocker for anyone building AI systems for Korean organizations.

We (TreeSoop) just released hwp-mcp, an open source MCP server that fixes this.

What it does

hwp-mcp exposes these tools via the Model Context Protocol:

• Extract text from .hwp / .hwpx files
• Parse tables into structured data
• Pull out embedded images
• Find-and-replace within documents
• Fill template variables (name, company, date)

Works on macOS and Windows. No Hancom Office license required.

Install in one line

claude mcp add hwp-mcp -- uvx --from hwp-mcp hwp-mcp

Works with Claude Code, Claude Desktop, VS Code Copilot, Cursor — anywhere that supports MCP.

Why this matters for Korean AI adoption

If you're building RAG systems, internal search, or document automation for Korean companies, 60–80% of the source documents will be HWP. Before hwp-mcp the options were:

1. Manual conversion (doesn't scale)
2. Hancom API licensing (Windows-only, paid)
3. Convert everything to Word org-wide (non-starter)

Now you just install the MCP and Claude reads HWP natively.

What we're using it for

TreeSoop uses hwp-mcp in:

• Corporate RAG chatbots ingesting HWP knowledge bases
• Government RFP automation (RFPs are distributed as HWP)
• Legal contract review (Korean law firm contracts = HWP)
• Meeting-note template auto-fill

Commercial use is fine. Contributions welcome.
