MCP Ultimate 2.2.1 — MCP server for LINE Official Account" width="720">

LINE OA MCP Ultimate

Operate your LINE Official Account from any AI agent — through natural language.

🛠️ Fixed in 2.2.1: run the MCP on your own server and point any AI agent at one URL — it now holds up through real sessions and full broadcasts (no more instant "Internal server error" in HTTP mode), and hosted pictures now cache properly, so thousands of customers opening your broadcast at once barely touch your machine. Thanks to a production field report by Norapat Limpagan! 🙏

🖼️ New in 2.2: attach a picture, say "send this as a Rich Message" — and it appears in your customers' chats. No hosting. No image resizing. No setup.

What is this?

line-oa-mcp-ultimate is a Model Context Protocol server that lets AI agents drive your LINE Official Account through natural conversation — no code, no API knowledge required.

Manage one OA or many — a single account needs just one env var, while agencies can register every client OA in one config file and switch between them with a single command (see Configuration).

It works with Claude Cowork, Claude Code, Cursor, Codex, ChatGPT desktop, OpenClaw, Hermes, or any MCP-compatible host.

Why use it?

LINE OA Manager works well — but it's a web UI you have to log into, click through, and operate manually. With this MCP server, the same operations become natural-language requests in your AI host of choice:

Instead of clicking through LINE OA Manager...	Just say...
Open broadcast composer → pick audience → write text → preview → schedule	"Send a Mother's Day promo to my Bangkok-based 25-44 female audience"
Resize the artwork to 5 sizes → find somewhere to host it → upload → paste URLs into a Rich Message	"ส่งรูปนี้เป็น Rich Message หาลูกค้าทุกคน" (attach the picture — that's the whole job)
Navigate Insight → Delivery → pick date range → screenshot	"Summarize last week's performance"
Open Audience → create from upload → upload CSV → wait	"Create an audience from this CSV: customers_last_month.csv"
Open Rich Menu → design tabs → upload images → set as default	"Build a Mother's Day rich menu and set it as default"
Open Coupon → check usage tab → cross-reference clicks	"How many people redeemed my Mother's Day coupon?"

The MCP server takes care of LINE Messaging API calls, pre-flight validation, quota safety, quiet-hour warnings, and Thai-localized templates. You stay in your AI host and operate your OA the way you think about it — by intent.
