## About

Argus adds autonomous QA to an MCP host such as Claude Code, Codex or Cursor. Given a URL, the agent explores user journeys in a browser, inspects what it sees and records bugs. Each finding is re-checked from a clean page load before it is marked verified. Tools are keyed by description, for example clicking "Login button". Reports can be written as HTML, JSON, JUnit and SARIF. A macOS screen profile tests native apps through the Accessibility tree.

It runs locally over stdio with uvx (package argus-testing, command argus-mcp). Chromium must be installed once through Playwright. The default core profile covers web testing; tool profiles screen and full are set with a flag or ARGUS\_TOOL\_PROFILE. No account is needed for MCP use.

## What it can do

- Explore a web app from a URL and look for unscripted bugs
- Re-verify each bug from a clean page load before certifying it
- Start sessions with goals, constraints and a time budget
- Track goal coverage and discovered pages during a session
- Export reports as HTML, JSON, JUnit and SARIF
- Test native macOS apps with the screen tool profile
- Re-check known bugs in CI with argus-regression

## Example prompts

- "Test my app at http://localhost:3000 and find real bugs."
- "Run a QA pass on our checkout flow and report only verified bugs."
- "Test the signup page with the goal of checking form validation."
- "Test the Notes app on my Mac for usability bugs."

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport stdio argus-testing -- uvx argus-testing
```

2. Start Claude Code and type `/mcp`. **argus-testing** should show as connected.

Add `--scope user` to make it available in every project.

### Claude Desktop

1. Open **Settings → Developer → Edit Config**. It opens `claude_desktop_config.json`. Add:

`claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "argus-testing": {
      "command": "uvx",
      "args": [
        "argus-testing"
      ]
    }
  }
}
```

2. Save the file and restart Claude Desktop.

Needs uv (Python) on your computer. The file lives in `~/Library/Application Support/Claude/` on macOS and `%APPDATA%\Claude\` on Windows.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=argus-testing&config=eyJjb21tYW5kIjoidXZ4IiwiYXJncyI6WyJhcmd1cy10ZXN0aW5nIl19>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "argus-testing": {
      "command": "uvx",
      "args": [
        "argus-testing"
      ]
    }
  }
}
```

Needs uv (Python) on your computer.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=argus-testing&config=%7B%22type%22%3A%22stdio%22%2C%22command%22%3A%22uvx%22%2C%22args%22%3A%5B%22argus-testing%22%5D%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"argus-testing","type":"stdio","command":"uvx","args":["argus-testing"]}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "argus-testing": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "argus-testing"
      ]
    }
  }
}
```

Needs uv (Python) on your computer.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "argus-testing": {
      "command": "uvx",
      "args": [
        "argus-testing"
      ]
    }
  }
}
```

2. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf.

### Codex

```bash
codex mcp add argus-testing -- uvx argus-testing
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.argus-testing]
command = "uvx"
args = ["argus-testing"]
```

Needs uv (Python) on your computer.

### Gemini CLI

```bash
gemini mcp add argus-testing uvx argus-testing
```

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients that start local servers accept this shape:

```json
{
  "mcpServers": {
    "argus-testing": {
      "command": "uvx",
      "args": [
        "argus-testing"
      ]
    }
  }
}
```

Zed puts servers under `context_servers` in its settings, with the same `command`, `args` and `env` fields.

Needs uv (Python) on your computer.
