- Runs on your computer with your user’s permissions (files, network, apps).
- The registry lists no key to fill in.
You need
- npmNode.js installed (for the npx command)
Which app do you use?
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
{

]
}
}
}Run this in your terminal
claude mcp add guard -- npx -y @codapult/guardOr copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"guard": {
"command": "npx",
"args": [
"-y",
"@codapult/guard"
]
}
}
}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.
Or copy the settings yourself
Paste into .vscode/mcp.json in your project
{
"servers": {
"guard": {
"type": "stdio",
"command": "npx",
"args": [
"-y",
"@codapult/guard"

}
}
}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 Guard 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 (0.13.3) reached the registry 4 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?

Architecture guardrails for AI-assisted development
Codapult Guard helps teams preserve the architecture that makes their project work as it changes. It maps a JavaScript or TypeScript codebase, lets the team approve project-specific boundaries, and checks future changes locally and in CI. AI agents can use the same project context and verification results as developers.
Catch project-specific regressions
A type checker can confirm that code is valid TypeScript. It cannot know that this project requires client components to stay away from persistence modules. Once the team approves that boundary, Guard can detect a violating import in changed files and show which rule was triggered.
Project boundary: Client → Server Action → Service → Repository → DatabasePossible regression: Client ─────────────────────────────────────→ Database
Guard discovers the architecture in the repository; it does not prescribe one universal structure or activate proposed rules without approval.
Get started
Requirements: Node.js >=20.19 and a JavaScript or TypeScript project.
# pnpmpnpm add -D @codapult/guard pnpm exec codapult-guard init
npm
npm install --save-dev @codapult/guard npx codapult-guard init
Review the generated project model, proposed rules, contracts, and baseline under .codapult/guard/ before relying on the results. Then run Guard's architecture checks:
pnpm exec codapult-guard verify --no-project-checks --tools offverify can run your configured project checks and detected adapters. The flags above limit this run to Guard's built-in checks. With npm, run npx codapult-guard verify --no-project-checks --tools off. See the complete guide for initialization and daily workflows.
Use Guard with an AI agent
Install a managed instruction block for your agent so it knows when to load Guard context and run verification:
pnpm exec codapult-guard install-agent codexSupported hosts and MCP setup are in the AI-agent integration guide and host integration guides.
The MCP server uses host-managed local stdio, with no network listener or application-level authentication. The host and operating system control process access and workspace permissions; see the security model.
Choose a GitHub setup
Choose a preset from the existing workflow templates and follow only the hosting steps for that level of protection. Most projects can start with standard PR checks.
| Preset | Use it when | Guide |
|---|---|---|
| PR checks | You want Guard findings and a required check on ordinary pull requests. | GitHub PR checks |
| Trusted PR verification | The Guard check must come from a protected workflow source, including for fork PRs. | Trusted PR setup |
| Merge queue | Your repository merges through a GitHub merge queue. | Merge queue setup |
If you are unsure, use PR checks first. It is useful CI feedback, but its workflow lives in the project being checked and can be changed by a pull request. Choose trusted verification when the check itself must be protected from that change.
What Guard does
- Learns project-specific structure, dependencies, boundaries, and existing findings.
- Checks approved architecture rules and contracts without imposing a universal architecture.
- Shows change impact and prepares bounded, redacted context for AI review.
- Runs configured project checks and adapters when enabled; it does not replace them.
- Produces deterministic CLI, JSON, and SARIF results for local use and CI.
Guard is local-first and does not call an LLM. The AI host owns model access, edits, and its repair loop. Guard complements TypeScript, ESLint or Biome, tests, SAST, and dependency scanners; it does not replace them.
