Un-Default MCP server

Un-Default

One thoughtful-language check for every way you build.

Formerly Anti-Default. Same tool — the name shifted so it reads as undoing

defaults, not opposing people. Old URLs under

darkai.ca/anti-default redirect here.

npx anti-default still works as an alias for npx -y anti-default.

Un-Default reviews copy, docs, UI strings, and live pages for racist defaults, sexist assumptions, ableist metaphors, and documented dogwhistles. It explains what it noticed and offers clearer alternatives.

No account. No AI required for matching. Open rules you can tune.

After Claude / Cursor writes UI copy

One command — skill + MCP + PR check. This is the habit that sticks:

npx -y anti-default init

That also writes examples/un-default-demo.md and prints a sample scan so you see a finding immediately. Browser demo (shareable): /?demo=1.

Or install the Claude Code plugin from this repo’s marketplace:

claude plugin marketplace add NomadBuilder/un-default
claude plugin install un-default@un-default

Paste-ready MCP JSON and Claude Project instructions:

Add it in under a minute

npx -y anti-default .

That is the whole local setup. It prints findings and exits non-zero on clear hits. Ambiguous or quoted matches stay advisory.

To pin it in a team project:

npm install --save-dev anti-default

Want the complete project setup?

npx -y anti-default init

init adds an ignore file, changed-files GitHub workflow, Cursor + Claude skills, .cursor/mcp.json + .mcp.json, Claude/Cursor after-edit hooks, CLAUDE.md instructions, and inclusive-check / inclusive-fix scripts. Existing files are never overwritten. Hooks surface hard findings back to the agent after Edit/Write so Claude keeps checking even when nobody remembers.

AI-copy habit (definition of done)

npx -y anti-default fix .          # safe 1:1 autofixes only
npx -y anti-default .              # remaining findings

Agents should not mark UI/docs work done until hard findings are cleared or explicitly marked fine in context. Soft/coded hits stay advisory.

# Preview autofixes without writing
npx -y anti-default fix . --dry-run

# Intentional language — suppress locally + share structured feedback
npx -y anti-default feedback --kind fine_in_context \
  --rule guys-generic --match "guys" --context "…snippet…" \
  --note "Quoted lyric" --open-issue
