Common questions

Is Checkmarx 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Overview

AI coding assistants generate code quickly, but that code can carry the same security risks as code written by hand. This repository connects Checkmarx One — Checkmarx's application security platform — to those assistants, so generated code is scanned for vulnerabilities as it's written, not after the fact.

This repository ships two complementary ways to bring Checkmarx One into an AI-assisted workflow. Use them together or separately — they solve different halves of the problem.

Checkmarx Security MCP — a hosted MCP server any MCP-capable assistant can call to scan, inspect findings, and apply AI remediation on demand.
Developer Assist plugins — fail-closed gates that scan scannable file writes *before* they land on disk, for Claude Code, Cursor, GitHub Copilot CLI, Codex CLI, and Gemini CLI.

Piece	What it does	When to use it
Checkmarx Security MCP	Tools the assistant can call — scan a project, inspect findings, apply AI remediation	You want on-demand scanning and fix-it workflows in any MCP client
Developer Assist plugins	A fail-closed gate — scannable file writes are scanned before they land on disk	You want the check to be automatic and non-optional

The plugins wrap the Checkmarx One CLI (ast-cli) (cx) for install, authentication, and native hook scanning, and they start the same MCP server for remediation.

Checkmarx Security MCP

A hosted MCP server that connects any MCP-capable AI client — Claude, Cursor, Copilot, Windsurf, Kiro — to Checkmarx One. It exposes scanning, findings, project management, and AI-generated remediation as tools your assistant can call in conversation.

Configure it once (see examples/ for per-client config) and ask.

Details → [README-MCP.md](README-MCP.md)

Cursor: MCP-only install

plugins/cx-cursor-plugin is a lightweight Cursor marketplace plugin that registers the Checkmarx MCP server only — no hook chain, no file-write gate, just the MCP tools. Use it when you want Checkmarx MCP tools in Cursor without adopting the Developer Assist gate.

Details → [plugins/cx-cursor-plugin/README.md](plugins/cx-cursor-plugin/README.md)

Developer Assist Plugins

Each plugin provides the same fail-closed security gate, wired in as a native hook for its client. Before the agent writes or edits a scannable file, the Checkmarx cx CLI scans the proposed content — real vulnerabilities are blocked rather than silently allowed, as is the case where the scanner itself can't be trusted to run. Shell commands are never gated. Findings are remediated through the bundled Checkmarx MCP server. Marketplace install and guided cx setup follow the same pattern across clients; only the client integration differs.

Plugin	Client	Details
`cx-devassist`	Claude Code	plugins/cx-devassist/README.md
`cursor-devassist`	Cursor	plugins/cursor-devassist/README.md
`copilot-devassist`	GitHub Copilot CLI	plugins/copilot-devassist/README.md
`codex-devassist`	Codex CLI	plugins/codex-devassist/README.md
Root extension	Gemini CLI	docs/gemini-cli-devassist.md

Checkmarx One CLI

The plugins install and drive the Checkmarx One CLI (cx) from Checkmarx/ast-cli. That CLI wraps Checkmarx One APIs for scans, authentication, and the native agent-hook scanners (ASCA, KICS, SCA).

Releases and platform downloads: ast-cli releases.

Documentation: Checkmarx One CLI tool.
