Knowmint

Overview

Knowmint is a Model Context Protocol server that connects AI agents to a knowledge marketplace built on Solana. It lets you discover, purchase, and retrieve human expertise directly through x402 payments, enabling your AI assistant to access specialized knowledge on demand as a native tool.

The server runs locally via the npm package @knowmint/mcp-server, communicating over stdio. You'll need to provide a KM_API_KEY environment variable to authenticate. The latest release is v0.1.4, published under the MIT license with source code available at Sou0327/knowmint on GitHub.

Knowmint appears in the AI & Agents category and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim your listing on mcp.site to verify ownership and keep the information up to date.
