MCP Stdio

MCP Stdio is a self-hosted gateway that connects local Model Context Protocol (MCP) clients—like Claude Desktop and Claude Code—to remote HTTP MCP servers. It acts as a bridge, enabling clients to communicate with remote servers using modern authentication schemes (OAuth 2.1, Bearer tokens, custom headers) and supports both current and legacy MCP transports. With advanced protocol compliance, auto-retry, streaming resilience, and robust error handling, MCP Stdio is intended for developers and technical users requiring secure and flexible MCP server connectivity.
