Implementation Reference

• word_document_server/tools/footnote_tools.py:99-156 (handler)

  Core implementation of the add_endnote_to_document tool. This async function handles document validation, adds a superscript dagger symbol as endnote reference to the specified paragraph, creates an 'Endnotes' section if needed, appends the endnote text, and saves the document.

  async def add_endnote_to_document(filename: str, paragraph_index: int, endnote_text: str) -> str:

• word_document_server/main.py:323-326 (registration)

  MCP tool registration for 'add_endnote_to_document' using the @mcp.tool() decorator. This sync wrapper delegates execution to the async implementation in footnote_tools.

  @mcp.tool()
  def add_endnote_to_document(filename: str, paragraph_index: int, endnote_text: str):
      """Add an endnote to a specific paragraph in a Word document."""
      return footnote_tools.add_endnote_to_document(filename, paragraph_index, endnote_text)

• word_document_server/tools/__init__.py:34-37 (helper)

  Re-export of add_endnote_to_document from footnote_tools.py, making it available when importing from the tools package.

  from word_document_server.tools.footnote_tools import (
      add_footnote_to_document, add_endnote_to_document,
      convert_footnotes_to_endnotes_in_document, customize_footnote_style
  )
