nablr (pronounced like “enabler”) is an MCP server that connects to your AI assistant and enforces quality gates across your entire software delivery lifecycle.
It ships 19 expert AI personas — product manager, architect, developer, tester, security owner, and more — each loaded with rules, standards, and escalation protocols. Free tier includes 40+ local code scanners and workflow tools.
The problem it solves
AI assistants accelerate typing, not engineering.
| What they promised | What actually happens |
|---|
| Ship faster | More code, same bugs |
| Higher quality | AI-generated tech debt |
| Reduce costs | Increased rework cycles |
nablr is the orchestration layer that fixes this — quality enforcement, workflow context, and persistent state that AI assistants lack by default.
| Metric | Without nablr | With nablr |
|---|
| Rework rate | ~30% of dev time | First-pass quality |
| Review cycles | 2.5 iterations avg | Single iteration |
| Defect escape to prod | 15% of features | Pre-development validation |
| Onboarding time | 3–6 months | Instant via CODE_MAP |
When to use nablr
Reach for nablr when:
- AI code ships defects — you use Cursor, Copilot, or Claude but can’t trust what merges
- Requirements aren’t buildable — stories get written but QA finds gaps after development
- Incidents recur — same root causes keep appearing with different symptoms
- Codebase is unknown — inherited system, no docs, no safe entry point for change
- Migrations stall — platform rewrites start without a complete map and discover unknowns mid-flight
- Governance is required — SOC2, ISO 27001, or internal audit trails needed for AI-assisted development
Not the right fit if your team doesn’t use an AI coding assistant — nablr augments the assistant, it doesn’t replace it.
How it works
nablr runs as a local MCP server alongside your AI assistant. When you invoke a persona, nablr injects the relevant rules, standards, and context directly into the conversation.
