hwpx-mcp-server 2.0.1

Model Context Protocol server for local HWPX document automation.

hwpx-mcp-server

Stateless MCP server for reading and editing HWPX documents with python-hwpx.

What Changed in v2

• Stateless tool design: every tool receives filename (or source_filename) and works in one call.
• No session/handle IDs in default workflow.
• Token-safe text responses with max_chars limits.
• LLM-friendly tool names (get_document_text, find_text, search_and_replace, batch_replace).
• Advanced XML/pipeline tools are opt-in with HWPX_MCP_ADVANCED=1.

Install

uvx hwpx-mcp-server

Requirements:

• Python 3.10+
• python-hwpx >= 1.9

MCP Client Config

Example (claude_desktop_config.json):

{
  "mcpServers": {
    "hwpx": {
      "command": "uvx",
      "args": ["hwpx-mcp-server"]
    }
  }
}

Core Tool Surface

Document

• create_document(filename, title?, author?)
• get_document_info(filename)
• get_document_text(filename, max_chars?)
• get_document_outline(filename)
• list_available_documents(directory?)
• copy_document(source_filename, destination_filename?)

Content

• add_heading(filename, text, level?)
• add_paragraph(filename, text, style?)
• insert_paragraph(filename, paragraph_index, text, style?)
• delete_paragraph(filename, paragraph_index)
• add_table(filename, rows, cols, data?)
• get_table_text(filename, table_index?)
• set_table_cell_text(filename, table_index, row, col, text)
• add_page_break(filename)
• add_memo(filename, paragraph_index, text)
• remove_memo(filename, paragraph_index)

Search / Replace

• find_text(filename, text_to_find, match_case?, max_results?)
• search_and_replace(filename, find_text, replace_text)
• batch_replace(filename, replacements)

batch_replace runs in order and saves once after all replacements.

Formatting

• format_text(filename, paragraph_index, start_pos, end_pos, ...)
• create_custom_style(filename, style_name, ...)
• list_styles(filename)
• format_table(filename, table_index, has_header_row?)
• merge_table_cells(filename, table_index, start_row, start_col, end_row, end_col)
• split_table_cell(filename, table_index, row, col)

Advanced Mode (Opt-in)

Set HWPX_MCP_ADVANCED=1 to enable advanced/debug tools:

• package_parts
• package_get_xml
• package_get_text
• object_find_by_tag
• object_find_by_attr
• plan_edit
• preview_edit
• apply_edit
• validate_structure
• lint_text_conventions

These tools are hidden by default.
