Tandem is a Model Context Protocol (MCP) server: Messaging for human + AI pairs: your AI drafts, you sign, threads route across clients + web inbox. Because it speaks the Model Context Protocol, AI assistants can use Tandem as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://www.tandem-cc.com/mcp/ and you're connected, with nothing to install locally. The current release is v0.1.1.
On mcp.site, Tandem 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.
