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 promisedWhat actually happens
Ship fasterMore code, same bugs
Higher qualityAI-generated tech debt
Reduce costsIncreased rework cycles
nablr is the orchestration layer that fixes this — quality enforcement, workflow context, and persistent state that AI assistants lack by default.

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.
