402registry

Overview

402registry is a Model Context Protocol server that lets you check whether AI crawlers can see your site. It offers free registry lookups with a pricing model denominated in x402, where verification checks are paid in USDC on the Base blockchain. Any MCP-compatible AI assistant can call 402registry's tools directly, letting the model decide when to use them during conversations or agent runs.

402registry runs as a remote hosted server. Simply point your MCP client to https://402registry.com/mcp to connect with no local installation needed. The current release is v1.0.0, and the server requires no authentication to get started.

402registry is listed in the Web Scraping category on mcp.site and integrates with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and others. If you maintain 402registry at 402registry.com, you can claim this listing to verify ownership, earn the Verified badge, and keep details up to date.
