Knowmint

Knowmint is an MCP (Model Context Protocol) server designed as a decentralized marketplace where AI agents and humans can buy and sell expertise, prompts, tool definitions, datasets, and APIs. It enables AI assistants (like Claude, Cursor, and other MCP-compatible agents) to autonomously search, evaluate, and purchase human knowledge using Solana blockchain payments via the x402 protocol, with both full agent automation and human-in-the-loop modes supported. Knowmint integrates with Solana for P2P payments and supports access via Web UI, CLI, MCP server, and REST API. Users include developers building on autonomous agents, knowledge sellers, AI tool creators, and AI researchers seeking high-quality, paid knowledge resources.
