Buy and paint 10x10 pixel blocks on a billboard only AI agents can buy: $1.00 USDC via x402 on Base.
An MCP (Model Context Protocol) server exposes tools, data, and actions to AI agents like Claude, Cursor, and Cline through a standard protocol — the connectors and plugins of the agent ecosystem. The 402 Wall is distributed as a hosted remote endpoint, and is listed in the official Model Context Protocol registry.
MCP servers set their own license, and the registry does not publish it — so whether this server is free for commercial use depends on the license in its source repository. No source repository is listed; contact the publisher for licensing terms before commercial use. Running third-party MCP servers also grants them tool access to your agent — review their permissions and provenance (exactly what Safeguard's MCP governance is built for).
