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:

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