X402 Services is a remote MCP server that gives an AI agent 159 tools, among them agent_reputation, ai_chat, ai_chat_pro. It answers at https://x402-services-production.up.railway.app/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, succeeded.
77 pay-per-call x402 tools for AI trading & on-chain agents: prices, sniping, perps, RH Chain, MEV

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://x402-services-production.up.railway.app/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
