Getting Started

The server is hosted, so there is nothing to install. Add the remote endpoint to your client: - Endpoint: https://email-spam-tester.com/mcp (streamable HTTP, no key, no account) - Claude Code: `claude mcp add --transport http email-spam-tester https://email-spam-tester.com/mcp` - Clients without streamable HTTP can bridge it with `npx -y mcp-remote https://email-spam-tester.com/mcp` Then ask the agent to test an email: it calls get_test_address, sends the real message to that address, and calls wait_for_report for the checks and the fix plan.

Example
{
  "mcpServers": {
    "email-spam-tester": {
      "url": "https://email-spam-tester.com/mcp"
