Publishes Markdown or HTML articles to your WeChat Official Account as drafts via a third-party relay API — no browser automation.

Automates publishing to 微信公众号 drafts. Uses an API key from wx.limyai.com (a third-party relay you authorize against your WeChat account) rather than wrangling cookies. Parses Markdown/HTML, auto-uploads images, saves as a draft for you to preview before hitting publish in the official backend.

Use Cases

Real-world ways to use wechat-article-publisher-skill

Publish a Markdown article to WeChat as a draft

👤 Bloggers who write in Markdown and also want to post to 公众号 ⏱ ~10 min beginner

When to use: You've written a post and want it as a WeChat draft without manual formatting.

Flow

Set the API key and pick the account

export WECHAT_API_KEY=... then ask Claude: 'publish my post.md to WeChat as a draft'.✓ Copied

→ Claude lists authorized accounts, you pick one
Review the draft in the WeChat backend

The skill confirms draft saved — open mp.weixin.qq.com and verify formatting.✓ Copied

→ Draft appears with images in place

Outcome: A polished draft you only need to review and click publish on.

Pitfalls

Markdown tables render poorly — Pre-convert tables to image or use simpler layouts — WeChat's renderer is limited
Images on external CDNs get blocked — Skill auto-uploads local images; be explicit about paths

Combine with: filesystem · superseo-skill

Tools

What this MCP exposes

Tool	Inputs	When to call	Cost
validate_key	WECHAT_API_KEY	First run each session	1 API call
upload_image	local image path	Per image in the article	1 API call per image
save_draft	title, body (md\|html), thumb_media_id, account_id	Final step	1 API call

Cost & Limits

What this costs to run

API quota: Depends on wx.limyai.com plan — typically free tier covers a handful of posts/day
Tokens per call: Small — skill drives an HTTP flow
Monetary: Free skill; relay API has its own pricing
Tip: Batch image uploads in one run to avoid repeated rate hits

Security

Permissions, secrets, blast radius

Minimum scopes: Draft write on your authorized WeChat Official Account

Credential storage: WECHAT_API_KEY in env var. Never paste into chat logs.

Data egress: Content + images go through wx.limyai.com -> WeChat. Trust is transitive on the relay.

Never grant: Publish (the skill is draft-only by design)

Third-party relay: treat wx.limyai.com as a semi-trusted intermediary. Don't send articles that must stay private pre-publish.
Always preview in the official WeChat backend before clicking publish.

Troubleshooting

Common errors and fixes

401 Unauthorized

WECHAT_API_KEY expired or not set. Re-issue at wx.limyai.com.

Verify: curl -H 'Authorization: Bearer $WECHAT_API_KEY' https://wx.limyai.com/health

Images not uploading

Check local paths are absolute and the process has read access

Verify: ls -l path/to/image

Formatting breaks in WeChat preview

Simplify Markdown (no nested lists, limit inline HTML) — WeChat's renderer is strict
