Repo Test Architect MCP server

Let your AI review your codebase and suggest which tests to write next, with evidence.

Developer tools Coding For it and development Developer Tools

Repo Test Architect is a helper that looks at your code project and tells you where tests are missing or weak. It works on many languages, including JavaScript, Python, C#, Go, Ruby, PHP, Swift, Rust, Kotlin, and Elixir. It is handy if you work on a codebase and want a clear, honest picture of your test coverage before you start writing new tests.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to a tool. This one connects your AI to Repo Test Architect, which reads your project files and builds a picture of your tests. Once connected, your AI can ask it to review your repository and come back with findings and a test plan.

What this MCP server does

You ask your AI to review your codebase for test gaps. Your AI passes that request to Repo Test Architect. The helper reads your project files locally, spots the languages and test frameworks in use, and builds a map of what is tested and what is not. It then ranks the most valuable test work and writes a plan with suggested commands. Your AI shows you the findings and the plan right in the chat.

Flow diagram: you ask your AI “Which files need tests most?”, on your own computer the Repo Test Architect MCP server works with your project files, and you get back test plan and findings.

What you can do with it

Review a whole repository and list test gaps
Rank which files most need tests
Generate a step-by-step test plan
Show which test frameworks your project uses
Report project stats like candidate counts and commands
Point out test placement issues across project boundaries
Run a readiness check on your local setup

Try asking your AI

“Analyze my repository and tell me which files need tests most.”
“Give me a test plan for the Python part of my project.”
“What test frameworks are used in this codebase?”
“Show me the top findings from a test architecture review.”

What it gives back to you

You get back a written summary of findings, a ranked list of test candidates, and a suggested test plan. It also includes project stats and the exact commands you can run to verify things. In the chat, this looks like a structured report with headings and bullet points, not raw code.

Before you start

What you need

Node.js 20 or newer installed on your computer
An MCP-capable client like Claude Desktop or another AI app that supports MCP servers
Your project files on the same computer where the helper runs

Good to know

This tool only reads your files and gives advice; it does not change your code, but treat its findings as review input rather than automatic instructions.

Install it with your AI

Add Repo Test Architect MCP server to your AI, no technical skills needed

You don't install anything by hand. You copy one prompt, paste it into an AI that can work on your computer, and it checks, installs and connects the server for you, asking you when it needs something.

Sign in to get the install prompt

Members get a ready-made prompt that lets the Claude desktop app check Repo Test Architect MCP server, install it and connect it for them, step by step. You don't need any technical skills: you copy, paste and answer a few questions. Your connected AI can also find and install any of the 4,066 MCP servers here for you.
