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.

TestMu AI (formerly LambdaTest) + Cursor FAQ

Common questions about integrating TestMu AI (formerly LambdaTest) MCP Server with Cursor.

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.
