Cyphrex is an MCP server with 9 tools an agent can call, among them check_action, get_audit_log, log_action. It answers at https://mcp.cyphrex.io/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 5 September 2026; the last check, on 18 October 2026, succeeded.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.cyphrex.io/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.
