List all WeChat (Weixin) bot accounts that have been logged in via QR code. Returns each account id, base URL, and whether it has a valid token.

Start an interactive WeChat login. A QR code is printed to the server's STDERR/terminal; scan it with the WeChat mobile app and confirm. Blocks until login completes or times out. For first-time setup it is usually easier to run npm run login in a real terminal. Returns the connected account id on success.

Remove a logged-in WeChat account: deletes its stored credentials, sync buffer, and cached context tokens. Provide the accountId from wechat_list_accounts.

Send a WeChat message to a user. Provide to (the recipient WeChat id, e.g. 'xxxx@im.wechat'), and text and/or media. media may be a local file path (absolute recommended) or a remote http(s) URL — images, videos, and other files are auto-detected by extension. If multiple accounts are logged in, pass accountId. The per-recipient context token (cached from inbound messages) is attached automatically when available. Outbound text is markdown-filtered by default (WeChat-unsupported syntax such as H5/H6 headings, CJK italics, and inline images is stripped; code blocks, tables, and bold are kept).

Poll for new inbound WeChat messages (one long-poll cycle). Returns messages received since the last poll; the server tracks a per-account sync cursor so repeated calls do not return duplicates. Media (images/voice/files/video) is downloaded and decrypted to local temp files by default, with the path returned in MediaPath. If multiple accounts are logged in, pass accountId.

Continuously poll until at least one inbound message arrives, an error occurs, or the listen window elapses. Unlike wechat_receive (a single poll cycle that often returns empty immediately), this re-polls back-to-back across the whole window — the correct way to wait for a message. Returns as soon as a message is received, with pollCycles and timedOut for diagnostics. Media is downloaded + decrypted to local temp files by default. If multiple accounts are logged in, pass accountId.

Show (or cancel) the '正在输入…' typing indicator to a WeChat user. Useful before a slow reply so the user sees the bot is working. The required typing ticket is resolved automatically. If multiple accounts are logged in, pass accountId.
