402registry
by @Georgi Kalchev
GitHubRemote MCP server (Streamable HTTP, no account, no API key) for 402registry, which checks whether AI agents and AI crawlers can actually see a website: a plain HTTP fetch with no JavaScript, the way GPTBot, ClaudeBot, PerplexityBot and OAI-SearchBot fetch pages. Every finding quotes what the fetch returned, with a fix. Tools: lookup_site (free), get_pricing (each product with its price and the exact x402 v2 payment requirements), get_docs (the machine guide as JSON) and get_service_status. A check costs $0.01, paid per request over x402 in USDC on Base.
Install
claude mcp add --transport http 402registry https://402registry.com/mcpHosted server
https://402registry.com/mcpThis server runs hosted, so there is no local process to install. The command above adds it to Claude Code, and the client configs below connect Claude Desktop, Cursor, and VS Code straight to the hosted endpoint. Any sign-in the server needs happens when you first connect.
Install with your client
claude mcp add --transport http 402registry https://402registry.com/mcp
Run this in a terminal to add the server to Claude Code.
What this does
402registry exposes a set of tools to Claude over the Model Context Protocol. It runs as a hosted server, so once you add it with the command above, those tools become callable inside any conversation, with nothing running on your machine.
