Mcp Document Converter

io.github.xt765Published by GitHub account xt765v0.2.2Updated Oct 24, 2026

Convert PDF, DOCX, HTML, Markdown, and Text for AI assistant context injection.

Overview

AI-generated overview

A local MCP server that converts documents between Markdown, HTML, DOCX, PDF and plain text so an assistant can read or produce them.

What you can do
Convert a document from one format to another, choosing source and output paths, target format, CSS, template and metadata options, with source format auto-detected from the extension when not given. Query format support: list supported formats, show the full conversion matrix, check whether a given source-to-target pair is possible, and get details on a single format. Outputs can include syntax highlighting, custom CSS styling and preserved title, author and creation metadata.
When to use it
Useful when an assistant needs to turn a PDF, Word file, HTML page or Markdown note into another format for context injection, or to produce a styled HTML or PDF from Markdown. Add it when document format conversion is a recurring part of the workflow.
Requirements
Runs as a local process on the user's machine, installed from PyPI (pip install mcp-document-converter) or launched with uvx; the README also shows running from a Git repository. Python and the listed dependencies, including WeasyPrint for PDF output, are needed. No authentication, API keys or headers are declared. Optional environment variables MCP_CONVERTER_LOG_LEVEL and MCP_CONVERTER_TEMP_DIR control logging and the temp directory.
Before you install
It reads files from paths the assistant supplies and writes converted output files, so point it only at directories you are comfortable exposing and check where output lands. PDF rendering relies on WeasyPrint and its system libraries. No credentials are requested, but converted documents are processed locally and may be passed into the assistant's context.

Installation

In SourceWeft

  1. Open Mcp Document Converter in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Core Components

  1. DocumentIR (Intermediate Representation): Unified abstraction for all documents, containing document tree, metadata, assets, etc.
  2. BaseParser (Parser Base Class): Defines the parser interface, parses various formats into DocumentIR
  3. BaseRenderer (Renderer Base Class): Defines the renderer interface, renders DocumentIR into various formats
  4. ConverterRegistry (Registry): Manages all parsers and renderers, provides format lookup and auto-matching
  5. DocumentConverter (Conversion Engine): Coordinates parsers and renderers to complete document conversion
