Jp Crypto Tax Rules is a remote MCP server that gives an AI agent 4 tools, among them get_rule_pack, get_tax_parameters, get_tax_rule. It answers at https://jp-crypto-tax-rules-62ko7b2uwa-an.a.run.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 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
