Name Clearance Engine

Check namespace availability across package registries, code hosts, and domain registries before committing to a name. Get a deterministic GREEN / YELLOW / RED opinion in seconds.

What it does

  • Checks namespace availability across npm, PyPI, GitHub, crates.io, Docker Hub, Hugging Face, and domains
  • Generates phonetic, homoglyph, and fuzzy variants to detect near-conflicts
  • Produces a deterministic GREEN / YELLOW / RED tier opinion with explainable scoring
  • Builds reservation links so you can claim handles immediately
  • Runs entirely locally — no API keys needed for core checks

What it does NOT do

  • Search trademark databases (USPTO, EUIPO, WIPO)
  • Provide legal advice or a legal opinion
  • Auto-register or auto-claim any namespaces
  • Replace professional trademark counsel

Quickstart

Run a one-off check without installing anything:

npx @mcptoolshop/clearance-opinion-engine check my-tool-name

Or install globally for repeated use:

npm install -g @mcptoolshop/clearance-opinion-engine
coe check my-tool-name --radar --suggest

How Tiers Work

GREEN

All namespaces available. No conflicts detected. Safe to claim.

YELLOW

Some concerns found. Review near-conflicts before proceeding.

RED

Direct conflicts detected. Name change recommended.
