ARC-Relay is a Model Context Protocol (MCP) server: DMARC-safe email forwarding for agents: aliases, DNS health checks, and MCP tools on your domains. Because it speaks the Model Context Protocol, AI assistants can use ARC-Relay as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://arc-relay.com/mcp and you're connected, with nothing to install locally. The current release is v1.2.0.
On mcp.site, ARC-Relay sits in the Communication category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
