Overview

Auth Posture is an MCP server that audits email domain security in a single call. It checks MX record receiving capabilities, evaluates SPF, DMARC, and DKIM spoofing protections, and identifies disposable address risks. Any MCP-compatible AI assistant can invoke its tools directly, letting the model decide when to run audits during conversations or agent workflows.

The server runs as a remote endpoint at https://auth-posture.rowb.app/mcp and requires only an API key for authentication. There is no local installation needed. The latest release is v1.0.0, available from the vendor at https://auth-posture.rowb.app.

Auth Posture appears in the Communication category on mcp.site and is compatible with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this server, claim this listing to verify ownership and keep information up to date.
