Email Deliverability is a Model Context Protocol (MCP) server: Scan and fix a domain's email deliverability (SPF, DKIM, DMARC, MTA-STS, BIMI, DNS blocklists). As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
It's a hosted (remote) server — point your client at https://mcp.inboxguard.io/mcp and you're connected, with nothing to install locally. The current release is v1.2.0.
You'll find Email Deliverability in the Communication category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
