three.ws Knock MCP Server

Let an agent reach a real person. Knock is a priced door to a human. ws/knock/ , and the owner sets what one message from a stranger costs. Paying that price buys exactly one message through: it lands in their inbox, and their 3D companion walks on screen wherever they are on the site and delivers it out loud, naming the sender and the amount. The USDC settles directly…. Its README documents 6 tools, including knock_quote, knock_directory, knock_send.

People who work with knock and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

One of 41 MCP servers published from nirholas/three.ws. Stars and repository activity are shared across all of them. See all 41 →
