What it solves

Wenyan MCP Server allows AI assistants (like Claude Desktop) to directly format and publish Markdown content to WeChat Official Accounts. It eliminates the need for manual copy-pasting between AI chat windows and third-party formatting tools, creating a seamless loop from content ideation to draft storage.

How it works

It implements the Model Context Protocol (MCP), providing a set of tools that an AI client can call to render Markdown into WeChat-compatible rich text, manage layout themes, and upload articles (including local and remote images) to the WeChat draft box. It can operate in two modes:

• Local Mode (Stdio): Directly calls the WeChat API from the local machine.
• Server Mode: Acts as a client that sends requests to a remote Wenyan Server to bypass IP whitelist restrictions and support team collaboration.

Who it’s for

Content creators and AI-assisted writers who publish to WeChat Official Accounts and want to automate their layout and publishing workflow using AI agents.

Highlights

• Direct Publishing: Converts Markdown to rich text and uploads directly to the WeChat draft box.
• Conversational Layout: Change themes and styles via natural language commands to the AI.
• Image Handling: Automatically uploads local, relative, or network images to the WeChat asset library.
• Theme Management: Includes built-in themes and supports registering custom CSS-based themes.
• Multi-Account Support: Ability to publish to multiple accounts when using Server Mode.
• Image-based Posts: Supports publishing "Little Green Book" style image-based messages.
