OutreachBox published its MCP server to npm in its first public release, letting Claude Desktop, Claude Code, Cursor, VS Code and other MCP clients run email outreach, prospecting, inbox triage, content campaigns and reporting in a workspace. It ships with a setup command, a health check and seven bundled playbooks that include when to ask before sending. The server only advertises the tools an API key's scopes allow, so a read only key never exposes a tool that sends mail, but keys created before scopes existed are treated as unrestricted.
Scoping tools by API key lets buyers grant send rights deliberately, but older keys carry no restrictions, so they should be checked or replaced before an AI client is connected.
