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": {
    "security-engineer": {
      "command": "npx",
      "args": [
        "-y",
        "@guardbee/mcp-security-engineer"
      ],
      "env": {
        "GUARDBEE_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add security-engineer --env GUARDBEE_API_KEY=your-value -- npx -y @guardbee/mcp-security-engineer

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": {
    "security-engineer": {
      "command": "npx",
      "args": [
        "-y",
        "@guardbee/mcp-security-engineer"
      ],
      "env": {
        "GUARDBEE_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": {
    "security-engineer": {

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.

Common questions

Is Security Engineer 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: GUARDBEE_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 (0.1.1) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

🇬🇧 English | 🇹🇷 Türkçe

Fix GuardBee AI Security Engineer findings in your own repository with your coding agent (Claude Code, Cursor, VS Code), then verify the fix on the live site.

GuardBee finds and explains the issue and proposes a fix for your platform. Your coding agent makes the change in your repository, and you approve it. GuardBee never edits your code or servers.

Telemetry is off by default. With GUARDBEE_TELEMETRY=1 it sends the server, tool, success, duration and short parameter values such as a file path; longer strings and fields like content, token or password are replaced with a placeholder. See @guardbee/mcp-telemetry.

Tools

Tool	What it does
`list_assessments`	Recent AI Security Engineer assessments of your workspace
`get_assessment`	Actionable findings, highest priority first, with the platforms each can be fixed on
`detect_stack`	Detects Next.js, Express, Nginx, Apache or Cloudflare from your repository's files, and finds config files to diff against
`get_fix`	A reviewable fix for a finding. If you pass your Nginx or Apache config, you get an exact diff.
`report_applied`	Records that the fix was applied, with the commit SHA or PR URL as a reference
`verify_fix`	After you deploy, re-runs the check that reported the finding against the live site

Setup

In GuardBee, open Developers → API keys and create a key with the remediations.read and remediations.write scopes.
Add the server to your agent.

Claude Code

claude mcp add guardbee-security-engineer -e GUARDBEE_API_KEY=gb_... -- npx -y @guardbee/mcp-security-engineer

Cursor / VS Code (mcp.json)

"mcpServers": { "guardbee-security-engineer": { "command": "npx", "args": ["-y", "@guardbee/mcp-security-engineer"], "env": { "GUARDBEE_API_KEY": "gb_..." } } } }

Example

"Fix the top GuardBee findings of my latest assessment in this repo."

The agent:

Calls list_assessments and then get_assessment.
Calls detect_stack. For example, it finds Next.js and deploy/nginx.conf.
Calls get_fix for each finding, edits next.config.js or the Nginx config, and shows you the diff.
After you approve and commit, calls report_applied with the commit SHA.
After you deploy, calls verify_fix, and GuardBee confirms the issue is resolved.

Configuration

Variable	Default
`GUARDBEE_API_KEY`	required
`GUARDBEE_BASE_URL`	`https://app.guardbee.ai`
`GUARDBEE_TELEMETRY`	off; `1` turns on anonymous usage telemetry

Security

The server only reads files inside the project root, and only the config file you name. Paths outside the root are rejected.
File edits are made by your agent, and you approve them there.
All actions are recorded in the GuardBee activity log, marked as coming from an MCP client.
