Base Transaction Decoder is a remote MCP server that gives an AI agent 2 tools, among them buy_pass, explain_transaction. It answers at https://api.0200project.com/mcp?ref=mcp-registry over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
