What the publisher says
From the OrangePro repository's README, as published. We do not edit it. Read it on GitHub
Find the behaviors your tests miss. Generate grounded tests that actually run.
OrangePro maps every public behavior in your codebase, scores each one by real test evidence, and shows you the structural blind spots before your users find them. Runs locally. Your code never leaves your machine.

What you get
One command produces an interactive HTML report:
npx -y @orangepro/mcp-server@latest start .
open .orangepro/behavior-coverage.htmlThe report has two modes: Simple (integration-level blind spots, plain English) and Expert (full behavior list, evidence tiers, flows, system map). Toggle with the pill switch at the top.
→ Live example: Twenty CRM (5,237 behaviors mapped)
System map — entry lanes (GraphQL, HTTP, Jobs) flowing into services, sized by traffic, colored by evidence tier, red-ringed by risk.
Priority gaps of another open source Project HONO — top 20 unproven behaviors ranked by blast radius, with generated test drafts.
Evidence tiers
Every behavior gets exactly one tier. Nothing is labeled "tested" on faith.
"Dynamically Proven 0" is normal on first run. Proof requires running tests against targeted mutations. That's the trust model.
Quick start
cd /path/to/your/repo
npm install # install the repo's own dependencies first
npx -y @orangepro/mcp-server@latest start .
open .orangepro/behavior-coverage.htmlShortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
Install directly
Runs npx -y @orangepro/mcp-server on your machine. Read the scan report first; the gateway never runs local packages.
