What is unique about LoadNinja's approach to load testing?

Unlike protocol-based tools, LoadNinja uses actual real browsers at scale. Your agent can trigger scenarios that execute scripts inside native browsers, ensuring your performance metrics accurately reflect the true end-user experience including client-side execution.

Can I stop a running test through my agent if I see performance degradation?

Yes. Use the `stop_test_run` tool with the active Run ID. Your agent will dispatch an immediate halt command to LoadNinja, stopping all physical load processes and allowing you to analyze the metrics captured up to that point.

How do I check my account's virtual user (VU) limits?

The `get_account` tool retrieves your subscription details and strict runtime VU limits. Your agent will report your current usage caps, ensuring you stay within your performance testing budget.

LoadNinja (Real-Browser Load Testing) + Cursor FAQ

Common questions about integrating LoadNinja (Real-Browser Load Testing) 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.
