Mail7 MCP server
Email validation for AI assistants. This is an MCP server that gives Claude, Cursor, Windsurf, Cline and any other MCP client four tools: verify a single address, clean a list, check a domain's SPF record, and audit a domain's whole mail configuration.
Honest by design: Mail7 answers Valid, Not Valid or , and the tool descriptions tell the model in plain words that Unknown means "could not be verified", not "bad". An assistant using this server will not silently delete addresses it could not check.
