Overview

DemiSignal is an MCP server that lets you check a domain's DMARC, SPF, DKIM, MX, BIMI and MTA-STS records directly from your AI assistant. It also generates SPF and DMARC records for you. Instead of switching between tools and copy-pasting results, you can call DemiSignal as a set of native tools within Claude, Cursor, VS Code, and other MCP clients.

DemiSignal runs as a hosted remote server at https://demisignal.com/mcp?utm_source=mcp-registry, so there's nothing to install or configure locally. Authentication is not required. The latest release is v1.0.0.

DemiSignal is listed in the Development category on mcp.site and works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain DemiSignal, claim this listing to verify your ownership, earn the Verified badge, and keep information up to date.
