Examples

URL Parsing (New Feature!)

Simply paste any TestRail URL and get the data automatically:

// Parse a test case URL
{
  "url": "https://moneyforward.tmxtestrail.com/index.php?/cases/view/2322865"
}
// Automatically detects it's a test case and retrieves case ID 2322865

// Parse a test run URL  
{
  "url": "https://company.testrail.io/runs/view/456"
}
// Automatically detects it's a test run and retrieves run details

// Parse test cases list with filters
{
  "url": "https://company.testrail.io/cases/123?suite_id=5&section_id=10"
}
// Automatically retrieves filtered test cases

Creating a Test Case

// Using the create_test_case tool
{
  "sectionId": 123,
  "title": "Test user login functionality",
  "type_id": 1,
  "priority_id": 2,
  "custom_steps_separated": [
    {
      "content": "Navigate to login page",
