Authenticated remote MCP server for publishing WeChat Official Account articles from Agents

About wechat-publisher-mcp

An MCP publishing service designed to run on a server with a stable public egress IP. It lets Codex and other MCP clients upload images, create WeChat Official Account drafts, and submit a draft for formal publication only after two independent confirmation gates.

v0.1.0 is ready to use. The complete image-rich draft workflow has been validated against a real subscription account.

- Supports one or more WeChat Official Accounts, selected through safe aliases - Uploads inline images to the WeChat CDN and cover images as permanent media - Creates, retrieves, and lists drafts with pagination - Submits drafts for formal publication and checks asynchronous publication status - Uses SQLite-backed idempotency records to prevent duplicate drafts or submissions after uncertain retries - Disables formal publication by default; both the server flag and explicit client confirmation are required - Exposes 9 MCP tools over Streamable HTTP with Bearer Token authentication - Includes the publish-wechat-remote Skill for image, draft, and publication workflows - Uses uv for Python environment management with the Aliyun PyPI mirror by default - Uses the DaoCloud mirror for the default Docker base image

Layer Choice --- --- Language Python 3.12+ MCP MCP Python SDK / Streamable HTTP HTTP Starlette + Uvicorn + HTTPX Configuration Pydantic Settings Idempotency store SQLite Package manager uv Deployment Docker Compose + Caddy / Nginx
