DOCX MCP for Claude Cowork and Codex

legalrabbit-docx-mcp enables your Claude Cowork and Codex to read and manipulate DOCX files locally.

Our MCP uses 2-5x fewer tokens than the Anthropic's docx skill, is faster, and is more reliable. There are 2 reasons:

1. Our MCP supports a bidirectional transformation of HTML <-> DOCX. AI will write HTML, not DOCX. It is well known that AI is excellent and efficient at processing HTML!
2. Our MCP supports "surgical editing". AI can specify which paragraph/table/row to edit without editing the entire doc. This saves a lot of tokens compared to the traditional docx skill that unzips a docx file and edits document.xml directly.

You can use our DOCX plugin together with Claude for Legal to enable a more seamless experience of working with a docx file!
