Wenyan MCP

Wenyan MCP Server enables AI to automatically format and publish Markdown articles to WeChat Official Accounts (微信公众号). It bridges the gap between AI writing and platform publishing, eliminating the need for manual copy-pasting through third-party editors.

Core Features

• Bypass formatting tools: AI-generated Markdown converts directly to WeChat rich-text and uploads automatically
• Conversational styling: Tell the AI "switch to orange theme" and styling updates instantly
• Complete workflow in one window: From brainstorming topics to writing, formatting, and saving drafts—all within a single chat interface
• Multi-platform support: Publish to WeChat Official Accounts, Zhihu, Toutiao, and more
• Built-in themes: Multiple beautiful formatting themes with custom theme support
• Image handling: Automatically uploads local and remote images to WeChat media library
• Cover images: Supports local paths, URLs, and relative paths
• Image posts (小绿书): Publish image-only messages with up to 20 images
• Server mode: Deploy remotely to bypass IP whitelist restrictions and enable team collaboration
• Multi-account publishing: Manage multiple WeChat Official Accounts (requires server mode)

Tools

• Render Markdown: Convert and format articles with selected themes
• Theme management: List, register custom themes, and delete themes
• Publish drafts: Upload formatted articles directly to WeChat draft box
