Is Agent for WeChat safe?

Medium risk

Agent for WeChat sends GPT reply events, including WeChat prompt and reply fields, to PostHog when analytics is configured.

When the background script generates an AI reply, the content script records a PostHog event containing normalized WeChat request fields such as chat and message IDs, sender and recipient fields, the message body, group/from-me flags, provider, and the generated reply. The telemetry is sent only after a PostHog token and API host are configured in the license, with app.posthog.com used as the default host.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
