Connect Cursor to Thunders MCP

Written by Ines

Connect Thunders to Cursor so your coding agent can create test cases, run them, and read back failures.

Before you start

  • A Thunders account

  • Cursor with a Pro plan or above

Option A: through the UI

  1. Open Cursor Settings then Tools & Integrations.

  2. Click New MCP Server. Cursor opens your mcp.json.

  3. Add the Thunders entry (see below), save, and go back to the settings screen.

  4. Thunders appears in the server list with a Needs login button. Click it.

  5. Sign in to Thunders and click Authorize. The server turns green with its tools listed.

Option B: edit the config directly

Add Thunders to ~/.cursor/mcp.json for every project, or to .cursor/mcp.json inside a single repo:

{
	"mcpServers": {
		"thunders": {
			"url": "https://api.thunders.ai/v1/mcp"
		}
	}
}

Save the file, then authorize from Cursor Settings then Tools & Integrations.

Verify it worked

In Agent mode, ask:

List all my Thunders projects

You should get back your project list.

Good to know. Put the config in .cursor/mcp.json and commit it, and everyone on the repo gets Thunders in Cursor. Each person still authorizes with their own Thunders account, so there are no shared credentials.
