Magic MCP vs ZapSign
A side-by-side look at the Magic MCP and ZapSign MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Magic MCP for architecture & design work as a local process; choose ZapSign for agreements & coordination over a hosted endpoint. You can also run both side by side in one mcpServers block.
