Designesy is a Model Context Protocol (MCP) server: Score any URL against a real design contract — 42 checks, A-F grade, token + motion validation. Because it speaks the Model Context Protocol, AI assistants can use Designesy as a set of callable tools instead of you copy-pasting between apps.
You can run Designesy two ways: connect to the hosted endpoint at https://www.designesy.org/api/mcp with no local install, or run it on your own machine via the Python package designesy-mcp (via uvx). The current release is v1.12.0, published under the MIT license, with source at LE-VAI/designesy-org on GitHub.
On mcp.site, Designesy sits in the Design category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
