What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Other
You need to fill in: GROQ_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: GROQ_API_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

PyPIPython’s uv installed (for the uvx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "code-sanitizer": {
      "command": "uvx",
      "args": [
        "mcp-code-sanitizer"
      ],
      "env": {
        "GROQ_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add code-sanitizer --env GROQ_API_KEY=your-value -- uvx mcp-code-sanitizer

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "code-sanitizer": {
      "command": "uvx",
      "args": [
        "mcp-code-sanitizer"
      ],
      "env": {
        "GROQ_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "code-sanitizer": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "mcp-code-sanitizer"
      ],
      "env": {
        "GROQ_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

GROQ_API_KEY secret required env
Groq API key from console.groq.com/keys

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is MCP Code Sanitizer safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: GROQ_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

(server.py) (llama-3.3-70b)

Features

Tool	What it does
`analyze_code`	Strict review — bugs, security issues, score 0–100
`compare_code`	Compares two versions, detects regressions, recommends merge/request_changes
`explain_code`	Step-by-step explanation for junior / middle / senior audience
`generate_tests`	Generates pytest / jest / go test — happy path, edge cases, security
`analyze_file`	Analyzes a whole file from disk with parallel chunking
`generate_report`	Builds an HTML report from any analysis result
`cache_info`	Cache statistics and clearing

Example output

"summary": "Critical SQL injection and secret exposed in logs", "score": 23, "issues": [ { "severity": "critical", "line": 2, "title": "SQL Injection", "description": "f-string directly interpolates user_id into query", "fix": "cursor.execute('SELECT * FROM users WHERE id = %s', (user_id,))" } ], "warnings": [{"title": "No exception handling", "description": "..."}], "suggestions": ["Consider using an ORM instead of raw SQL"] }

Installation

Prerequisite: Get a free Groq API key at console.groq.com/keys — no credit card required.

Claude Code CLI

claude mcp add code-sanitizer -e GROQ_API_KEY=gsk_your_key -- uvx mcp-code-sanitizer

Claude Desktop

OS	Config file
macOS	`~/Library/Application Support/Claude/claude_desktop_config.json`
Windows	`%APPDATA%\Claude\claude_desktop_config.json`
Linux	`~/.config/Claude/claude_desktop_config.json`

"mcpServers": { "code-sanitizer": { "command": "uvx", "args": ["mcp-code-sanitizer"], "env": { "GROQ_API_KEY": "gsk_your_key_here" } } } }

Cursor

Create .cursor/mcp.json in your project (or ~/.cursor/mcp.json globally):

"mcpServers": { "code-sanitizer": { "command": "uvx", "args": ["mcp-code-sanitizer"], "env": { "GROQ_API_KEY": "gsk_your_key_here" } } } }

VS Code

Requires VS Code 1.99+ with GitHub Copilot. Create .vscode/mcp.json in your project:

"servers": { "code-sanitizer": { "command": "uvx", "args": ["mcp-code-sanitizer"], "env": { "GROQ_API_KEY": "gsk_your_key_here" } } } }

Or add globally via Ctrl+Shift+P → "MCP: Add Server".

Don't have `uvx`? Install it with pip install uv, then use the commands above.

Manual install (alternative)

If you prefer cloning the repo:

git clone https://github.com/notasandy/mcp-code-sanitizer

cd mcp-code-sanitizer pip install -r requirements.txt cp .env.example .env # add your GROQ_API_KEY python server.py

Then point the client config to:

"command": "python", "args": ["/full/path/to/server.py"], "env": { "GROQ_API_KEY": "gsk_your_key_here" } }

GitHub Action — automatic PR review

Add AI code review to any repository in 5 lines. The action posts a structured comment on every PR with score, issues, and fix suggestions.

# .github/workflows/ai-review.yml

name: AI Code Review on: pull_request: types: [opened, synchronize]

permissions: contents: read pull-requests: write

jobs: review: runs-on: ubuntu-latest steps:

uses: notasandy/mcp-code-sanitizer@v1 with: groq_api_key: ${{ secrets.GROQ_API_KEY }}

Add GROQ_API_KEY to your repository secrets → Settings → Secrets → Actions.

The action automatically:

Reviews only changed files (up to 10 per PR)
Posts a score and structured issue list as a PR comment
Fails the check if critical issues are found

Usage in chat

After connecting, just write naturally:

Review this code for vulnerabilities:

def get_user(user_id): query = f"SELECT * FROM users WHERE id = {user_id}" return db.execute(query)

Or call tools explicitly:

analyze_file /path/to/my_script.py

generate_tests for this function: ... compare_code — before vs after refactor, did it get better? generate_report and save to /tmp/report.html
