Getting a Flask application to work is one thing. Getting it ready for production is another.
I have built and deployed enough Flask applications to see how easy it is to focus on whether a feature works while overlooking the things that determine whether the system can be safely and reliably deployed.
That is why I built Flask Production MCP.
What it does
Flask Production MCP is a static production-readiness auditor for Flask applications.
It checks nine areas:
- Flask structure
- Architecture
- Templates
- Deployment
- Testing
- Security
- Database design
- Dependencies
- Code quality
It looks for issues such as missing CSRF protection, debug mode, hardcoded secrets, insecure Docker configuration, missing rate limiting, vulnerable dependencies, database performance concerns and weak testing coverage.
It does all of this without importing or running the application.
More than a security scanner
The question I wanted the tool to answer wasn't:
"Does this application have security vulnerabilities?"
It was:
"Is this Flask application ready to deploy?"
That requires looking at the whole system.
A missing database index may not be a security vulnerability. A development server in a production container may not be a code bug. A missing migration strategy may not break the application today.
But these things can become real problems as the system grows.
Built for developers and AI agents
The auditor can be used three ways:
CLI → pre-commit → GitHub Actions

AI coding agentThe MCP interface allows an AI coding agent to run the same production audit while working on the project.
Instead of simply asking an agent to write code, I can also ask it to check whether the resulting application is production ready.
The audit separates blockers, advisories and notes, so developers can focus on what actually needs attention.
Why I built it
This project reflects how I approach software generally.
I don't want to build systems that merely work. I want to build systems that can be trusted, maintained and relied upon.
For businesses, that distinction matters.
Software becomes part of an operation. If it is poorly designed, the business eventually pays for it through downtime, security problems, manual work or expensive rewrites.
Flask Production MCP is a small tool, but it comes from that bigger idea:
Don't wait for production to expose problems you could have found during development.
