Who is this for?
- QA Automation Engineers — monitor build health and inspect diagnostic logs through natural conversation without leaving your IDE or switching to the dashboard
- Software Developers — retrieve session screenshots and videos to debug UI failures directly from your workspace for rapid iteration
- DevOps Teams — audit CI/CD test results and monitor secure tunnel connections across different testing environments efficiently

Why Cursor?
Cursor's Agent mode turns TestMu AI (formerly LambdaTest) into an in-editor superpower. Ask Cursor to generate code using live data from TestMu AI (formerly LambdaTest) and it fetches, processes, and writes. all in a single agentic loop. 10 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Frequently asked questions
Can I see the exact console errors from a failed browser test through my agent?
Yes. Use the get_session_details tool with a specific Session ID. Your agent will retrieve full metadata including console logs, network configurations, and execution artifacts, helping you identify the root cause of the failure instantly.
How do I retrieve the video recording of a specific test execution?
Ask your agent to get_session_video for a targeted Session ID. Your agent will return the absolute MP4 URL to stream or download the complete browser session recording, which is essential for debugging flakey UI bugs.
Can my agent check if our secure localhost tunnel is active?
Absolutely. Use the list_active_tunnels tool to identify dedicated private connection endpoints. Your agent will report which TestMu AI tunnels are currently running, ensuring you can test local environments from the cloud.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
