Visión general

Arc Relay is a management proxy for Model Context Protocol (MCP) servers. It sits between your AI tools (Claude Code, Claude Desktop, Cursor, etc.) and your MCP servers, providing a single authenticated endpoint that handles Docker container lifecycle, health monitoring, OAuth flows, access control, and multi-transport proxying. Manage all your MCP servers from one web UI. (Formerly MCP Wrangler)
