Install Kaption’s remote MCP server in Cursor or VS Code with one click, or paste it into mcp.json. Your editor’s agent can then read chats, find contacts and schedule follow-ups.
MCP server address
https://mcp.kaptionai.com/mcpmcp.json
{
"mcpServers": {
"whatsapp": {
"url": "https://mcp.kaptionai.com/mcp"
}
}
}Pull the exact wording of a bug report a client sent on WhatsApp, or schedule a “deployed, please check” message when you ship, without leaving the editor.
Open WhatsApp Web in Chrome or Edge with the Kaption extension, then AI Assistants (MCP) › Cloud Bridge › Enable. In the Kaption desktop app, switch on Cloud MCP in Settings. Keep it open while the assistant works: the tools only reach WhatsApp while Kaption runs.
Click Add to Cursor (or Add to VS Code) below. Or add the server to ~/.cursor/mcp.json for every project, or .cursor/mcp.json for one project.
The app opens Kaption’s sign-in page. Enter your phone number, type the 6-digit code Kaption sends you on WhatsApp, and choose how long the connection lasts: while you use it (it ends after 90 days without use), 1 year, or until you disconnect it.
In the agent chat, ask about your WhatsApp. Cursor uses OAuth with dynamic registration, so there is no key to paste.
MCP server address

}Prefer the connection on your computer? Use the local server: npx -y @kaptionai/mcp-extension@latest (Node.js 18 or newer). The JSON for it is on the MCP page.
Windsurf, Zed and any client that supports remote MCP with OAuth use the same address.
Search and read chats, summarize conversations, look up contacts and groups, manage labels, notes and reminders, and schedule a message after you confirm it.
No message is sent immediately. The assistant can schedule one message to one 1:1 chat, up to 800 characters, and it should confirm the text and the time with you first. Locked chats are never visible to it.
No. The relay at mcp.kaptionai.com checks your sign-in and passes each request to Kaption on your computer, which runs it against your WhatsApp and sends back only the answer.
Kaption is closed, or Cloud MCP is off. Open WhatsApp Web with the Kaption extension, or the desktop app, and turn the connection on.
Turn on Cloud MCP in Kaption and click Add to Cursor.
