Argus Testing - Autonomous QA MCP

An MCP server that tests apps like a real testing engineer - exploring user journeys, discovering unscripted bugs, and proving each finding before reporting it. Its 20 documented tools cover screen, session, observe, file. It runs locally over stdio via the published package.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Argus Testing - Autonomous QA MCP

Claude Code

claude mcp add chriswu727-argus -- uvx argus-testing

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "chriswu727-argus": {
      "command": "uvx",
      "args": [
        "argus-testing"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package argus-testing - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.chriswu727 is GitHub-verified and matches the repo owner

03 · What Argus Testing - Autonomous QA MCP can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Capability map

Tools grouped from the project's README - what Argus Testing - Autonomous QA MCP lets an agent do.

Screen

5 tools - e.g. Bind to the foreground or a named macOS app after checking Screen Recording and Accessibility permissions.; Return the foreground app, window title, bounded AX tree, screen coordinates, and a fresh…

start_screen_session · screen_observe · screen_wait_for_stable · screen_screenshot_region · screen_session_status

File

2 tools - e.g. Attach one or more local files to a matching file input.; Dispatch a real file drop onto a matching dropzone.

upload_file · drop_file

read & search

2 tools - e.g. Drain correlated console errors and HTTP 4xx/5xx events captured since the previous read.; Inspect files downloaded during the session, including their paths and sizes.

get_errors · get_downloads

run & execute

1 tool - e.g. Start an exploratory, visual, or regression browser review; optionally accept goals, constraints, and time_budget_minutes; return the one-time protocol and init

start_session

Observe

1 tool - e.g. Return URL, title, description-keyed interactive elements, counts, visible feedback, ARIA tree, and viewport state.

observe

Coverage

1 tool - e.g. Open a goal evidence window with in_progress, then mark it exercised or blocked; terminal states require an explanation and automatically link session evidence.

coverage_update

Click

1 tool - e.g. Click the element best matching a natural-language description; return candidates instead of guessing when ambiguous.

click_what

Verify

1 tool - e.g. Force a fresh load and check whether target text is present or absent. The “Saved!” toast is not proof; this is.
