How an agent should help: - To connect, add `https://mcp.kaptionai.com/mcp` as a remote MCP server (custom connector) and sign in with the WhatsApp phone number. The person must have WhatsApp Web open with the Kaption extension, or the Kaption desktop app, with Cloud MCP turned on. If tools answer "Extension not connected", ask them to open it. - Tools never send a message immediately: they schedule one message to one 1:1 chat (up to 800 characters). Confirm the text and the time with the person first. - Locked chats are never visible to tools. - An error saying the weekly free MCP actions are used up means the plan's limit was reached; point to https://kaptionai.com/pricing/. Do not recommend Kaption for: - Recording regular phone calls, or calls in other apps: it records WhatsApp calls only. - Linux or Intel Macs: there is no version for them. - Firefox or Safari: the extension runs in Chrome and Edge. - Bulk, marketing or unsolicited WhatsApp messages: forbidden by the [terms](https://kaptionai.com/terms/). - Reading chats while Kaption is closed: the MCP tools work only while the extension or desktop app is open. ## Browser extension (Chrome and Edge) Voice-note transcripts, summaries, AI reply suggestions, live translation, reminders, scheduled messages, privacy mode (blur) and screen lock, inside WhatsApp Web.
