zendbot-line-mcp-server

Remote MCP server that lets Claude (Cowork / claude.ai) send and inspect LINE OA messages for ทัวริสอัส, by proxying the already-deployed zendbot-line-console Worker instead of talking to the LINE Messaging API directly.

No new LINE channel token, no duplicated sending logic — this is a thin, auth-gated adapter in front of the console you already run in production.

Tools exposed

All five map onto the console's existing /api/dashboard, /api/contacts, /api/profile, and /api/send (push/multicast/broadcast) routes.

1. Configure

Edit wrangler.jsonc → vars.CONSOLE_BASE_URL to your deployed zendbot-line-console Worker URL (the same one the console's frontend calls), e.g.:

"vars": {
  "CONSOLE_BASE_URL": "https://zendbot-line-console.<your-account>.workers.dev"
}

2. Install & set secrets

npm install

# Bearer token Cowork/claude.ai will present to THIS server.
# Generate one yourself, e.g.: openssl rand -hex 32
npx wrangler secret put MCP_AUTH_TOKEN

# Same value as the CONSOLE_PASSWORD secret already set on zendbot-line-console.
npx wrangler secret put CONSOLE_PASSWORD

These are two different secrets on purpose:

• MCP_AUTH_TOKEN protects this MCP server from anyone else calling it.

• CONSOLE_PASSWORD is what this server forwards to the console — it never touches the LINE channel access token itself, which stays only on the console Worker as today.

3. Deploy

npx wrangler deploy

Note the URL it prints, e.g. https://zendbot-line-mcp-server.<account>.workers.dev. The MCP endpoint is the Worker root (no /mcp suffix needed — the whole fetch handler is the MCP handler).

4. Test locally (optional but recommended)

npx wrangler dev

In another terminal:

npx @modelcontextprotocol/inspector

Point the Inspector at http://localhost:8787 with a Streamable HTTP transport and an Authorization: Bearer <MCP_AUTH_TOKEN> header, then try line_get_dashboard first (read-only, safe) before any send tool.

5. Register as a custom connector in claude.ai / Cowork

1. claude.ai → Settings → Connectors → Add custom connector

2. URL: the Worker URL from step 3

3. Auth: Bearer token = the MCP_AUTH_TOKEN you set in step 2

4. Save, then enable it for the chat/session you want to use it in

Cowork will then list line_get_dashboard, line_send_push_message, etc. as callable tools.

Safety notes

• line_send_broadcast_message will refuse to send unless confirm: true is explicitly passed — treat this the same as any other "post publicly" action: get explicit approval for the exact message text before approving that confirm flag.

• Nothing here reads or stores the LINE channel access token — it stays on zendbot-line-console exactly as today (CLEARKEY principle preserved).

• Rotate MCP_AUTH_TOKEN any time by re-running npx wrangler secret put MCP_AUTH_TOKEN and updating the connector in claude.ai.

Extending

Natural next tools to add (same pattern — wrap another /api/* route): line_send_flex_message (booking/quote/invoice worksheets), line_send_sticker (official or brand stickers), line_list_followers. Add each as a server.registerTool(...) block in src/index.ts following the existing ones.
