Transport: stdio
Category: Cybersecurity

Install

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

Before you install

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": {
    "agentguard": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/shuaicongxiaomai/agentguard:0.1.2"
      ]
    }
  }
}

Run this in your terminal

claude mcp add agentguard -- docker run -i --rm ghcr.io/shuaicongxiaomai/agentguard:0.1.2

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "agentguard": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/shuaicongxiaomai/agentguard:0.1.2"
      ]
    }
  }
}

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": {
    "agentguard": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/shuaicongxiaomai/agentguard:0.1.2"
      ]
    }
  }
}

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.

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 AgentGuard — security checks for AI agents 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (0.1.2) reached the registry 4 months ago.

Which apps can use it?

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

AgentGuard — security checks for AI agents (MCP server)

A free, open-source, single-binary MCP server that gives any AI agent (Claude Desktop, Cursor, Claude Code, …) security checks in the loop:

Tool	What it does	Data source
`scan_secrets`	Flags hard-coded secrets (API keys, tokens, private keys) in text/code/diffs before the agent commits, logs, or sends them. Runs locally; values are masked.	local (regex + entropy)
`check_cve`	Whether a specific package version has known CVEs, with severity + fixed version.	OSV.dev (free)
`scan_dependencies`	Scans a `go.mod` / `package.json` / `requirements.txt` and reports every vulnerable pinned dependency.	OSV.dev (free)

No API key, no account, no telemetry. Everything runs locally except CVE lookups, which hit the free public OSV.dev API.

Install

Pick whichever fits your setup. All three give the same stdio MCP server.

Docker (no Go toolchain needed)

docker run -i --rm ghcr.io/shuaicongxiaomai/agentguard:latest demo

MCP client config (mcpServers block in Claude Desktop / Cursor / Claude Code):

"mcpServers": { "agentguard": { "command": "docker", "args": ["run", "-i", "--rm", "ghcr.io/shuaicongxiaomai/agentguard:latest"] } } }

Go install

go install github.com/shuaicongxiaomai/agentguard@latest

{ "mcpServers": { "agentguard": { "command": "agentguard" } } }

Prebuilt binary

Download the archive for your OS/arch from the Releases page, extract it, and point the config command at the absolute path to the binary.

Build from source

go build -o agentguard .          # append .exe on Windows

Three ways to run it

1. `demo` — see it work, zero config:

agentguard demo

Runs all three tools on sample inputs and prints the results.

2. stdio (default) — local use; the MCP client launches the binary. No port; the client manages its lifecycle. Use any of the configs above, then ask your agent: *"scan this for secrets"*, *"is lodash 4.17.20 vulnerable?"*, *"check my package.json for vulnerable deps."*

3. `serve` — Streamable HTTP service on a port (for a hosted/remote server):

agentguard serve :8080          # or set PORT=8080

health: GET http://host:8080/healthz

MCP URL: POST http://host:8080/mcp (clients connect to this URL)

Use stdio for local use; use serve when you want a hosted server users connect to by URL without installing anything.

Notes

scan_secrets runs locally and never returns raw secret values — only masked previews.
scan_dependencies caps at 200 deps per call and queries OSV concurrently.
check_cve / scan_dependencies need network access to OSV.dev; scan_secrets is fully offline.
