Connect Claude to Thunders MCP

Written by Ines

Connect Thunders to Claude so you can author, run and debug tests from a conversation, on the web, in the desktop app, or in Claude Code.

Before you start

  • A Thunders account

  • A paid Claude plan (Pro, Max, Team or Enterprise). Custom connectors are not available on the free plan.

Claude on the web and desktop

  1. Open Settings then Connectors.

  2. Click Add custom connector.

  3. Fill in the two fields:

    • Name: Thunders

    • Remote MCP server URL: https://api.thunders.ai/v1/mcp

  4. Click Add. Thunders now appears in your connector list.

  5. Click Connect. Claude opens the Thunders sign-in page.

  6. Sign in to Thunders if you are not already, review the access being requested, and click Authorize.

  7. You are returned to Claude and the connector shows as connected.

The steps are identical in the Claude desktop app. Connectors are shared across web and desktop, so connecting in one place connects both.

Claude Code

Run this once in your terminal:

claude mcp add --transport http thunders https://api.thunders.ai/v1/mcp

Then start Claude Code and run /mcp. Select thunders and follow the browser prompt to authorize.

Verify it worked

Ask Claude:

List all my Thunders projects

You should get back your project list.

Good to know. Claude asks for your approval the first time it calls each tool. Tools that change something, such as creating a test case or queuing a run, always ask before they act.
