MarkupBase is a Model Context Protocol (MCP) server: Versioned artifact review for people and AI agents, with contextual comments and human control. Because it speaks the Model Context Protocol, AI assistants can use MarkupBase as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://mcp.markupbase.com/mcp and you're connected, with nothing to install locally. The current release is v0.2.2.
On mcp.site, MarkupBase sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
