Un-Default

Overview

Un-Default is a Model Context Protocol server that catches racist, sexist, and ableist defaults in AI-generated and human-written copy. It uses local rules to identify problematic language patterns without requiring any external accounts or services.

The server runs entirely on your machine through the npm package anti-default, communicating over stdio with your MCP client. No authentication is needed—it works immediately after installation. Version v0.5.6 is available under the MIT license, with full source code at NomadBuilder/anti-default on GitHub.

Un-Default belongs in the AI & Agents category and integrates with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this project, claim your listing on mcp.site to earn a Verified badge and keep information up to date.
