Arc Relay sits between your AI tools and MCP servers, providing auth, policy controls, traffic interception, and archiving - not just proxying. Features - Unified proxy - all MCP servers behind one endpoint ( /mcp/{server-name} ) - Middleware pipeline - bidirectional request/response processing (sanitizer, sizer, alerter, archive) - Archive with encryption - stream tool calls to any webhook, optionally encrypted with NaCl Box - Docker lifecycle - auto-start, stop, health check, and recover containers - Multi-transport - stdio (Docker), HTTP (Docker/external), remote (SSE/OAuth) - Auth - session cookies (web UI) + Bearer API keys (proxy) + OAuth 2.1 (remote servers) - Access tiers - per-endpoint risk-based access control with auto-classification - Web UI - manage servers, users, API keys, middleware, and logs - CLI tool ( arc-sync ) - sync MCP servers to Claude Code projects via .mcp.json - Health monitoring - periodic pings with auto-recovery for failed servers Quick Start Docker Compose From Source Requires Go 1.24+, GCC, and SQLite dev headers. One-click Deploy (Render, Heroku, Railway) The repo ships deploy manifests for common PaaS platforms: Platform File Notes --- --- --- Render render.yaml Persistent 1GB disk for SQLite, secrets auto-generated.
