Cursor + MCP QA Agent

MCP quality checks

A local Model Context Protocol server that gives Cursor Agent three focused QA tools, plus project rules and reusable workflows.

What the agent can do

MCP tool

Purpose

analyze_user_story

Extract criteria, risks, and open questions

create_test_charter

Build a timeboxed risk-based exploratory session

draft_bug_report

Format verified evidence without inventing missing details

Architecture

Cursor Agent
  ├─ .cursor/rules/qa-agent.mdc  → behavior and safety rules
  └─ .cursor/mcp.json            → local stdio connection
                ↓
       QA MCP server (TypeScript)
          ├─ analyze story
          ├─ create charter
          └─ draft bug report

Cursor provides the AI reasoning. The MCP server provides small, validated, deterministic tools.

Run and connect

npm install
npm run build
npm run smoke

Then open the repository in Cursor. The project-level .cursor/mcp.json registers the built server. Confirm portfolio-qa-toolkit is enabled in Cursor settings, open Agent, and paste the feature review prompt.

Why this is safe by default

  • Tools do not access the filesystem, shell, network, or issue trackers.

  • Zod validates every input before execution.

  • Rules prohibit invented evidence and secrets.

  • Bug severity remains a human decision.

  • The MCP smoke test launches the server, discovers tools, and calls one through the real protocol.

Interview demo (3 minutes)

  1. Show .cursor/mcp.json and the three tools in Cursor.

  2. Paste the feature review prompt.

  3. Let Agent call analyze_user_story, then create a charter.

  4. Explain the boundary: Agent reasons; MCP supplies validated capabilities; a human approves conclusions.

  • MCP Server By TestMu AIOAuth
    com.lambdatest.mcp

    Run, debug, and triage tests from your IDE using natural language, no dashboard switching, no manual data transfers. The TestMu AI (formerly LambdaTest) MCP Server is a single remote server exposing four tool suites: HyperExecute — analyze your project, generate YAML configs and test runner commands, then monitor jobs and sessions. Automation — pull a TestID's details plus command, network, and console logs into one chat for instant root-cause analysis. Includes mobile app upload. SmartUI — explain pixel, layout, DOM, and perceptual changes in a visual regression run, with context-aware React/HTML/CSS fixes. Accessibility — audit any public URL or a local React app against WCAG and get ready-to-apply remediation steps. Connects over https://mcp.lambdatest.com/mcp using OAuth 2.1 — no API keys in your config. One-click install in Cursor; works with Claude, GitHub Copilot, Cline, and any MCP client. Tests execute on the TestMu AI cloud: 3,000+ browsers and 10,000+ real devices.
