Inbox Preview is a Model Context Protocol (MCP) server: Render HTML/.eml emails in real Gmail, Outlook & Yahoo web clients and screenshot them. Because it speaks the Model Context Protocol, AI assistants can use Inbox Preview as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://api.powerline.ai/v1/mcp and you're connected, with nothing to install locally. The current release is v0.1.0.
On mcp.site, Inbox Preview sits in the Communication category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
