TestRail MCP Server

A Model Context Protocol (MCP) server that connects AI assistants to TestRail test management — search, create, update, and execute test cases using natural language.

Why TestRail MCP Server?

Managing test cases manually is tedious. With the TestRail MCP Server, your AI assistant (Claude, Cursor, Windsurf, or any MCP-compliant client) talks directly to TestRail. Ask it to find test cases, create new ones, kick off test runs, or report results — all through natural conversation.

No context switching. No copy-pasting. Just ask.

✨ Features

Category	Capabilities
🔍 Discovery	Browse projects, suites, and sections to map your test organization
📋 Case Management	Fetch, create, update, and bulk-edit test cases with full custom field support
▶️ Test Execution	Create runs, record results, attach files, and track test statuses
🧠 Context-Aware	Exposes templates, field definitions, priorities, and case types so LLMs generate valid, well-structured test cases

🚀 Quick Start

1. Get Your TestRail API Key

Navigate to My Settings → API Keys in your TestRail instance and generate a new key.

2. Configure Your MCP Client

Add the server to your MCP client configuration. Below are examples for popular clients.

Claude Desktop

Edit your claude_desktop_config.json:

{
  "mcpServers": {
    "testrail": {
      "command": "npx",
      "args": ["-y", "@uarlouski/testrail-mcp-server@latest"],
      "env": {
        "TESTRAIL_INSTANCE_URL": "https://your-instance.testrail.io",
        "TESTRAIL_USERNAME": "your@email.com",
        "TESTRAIL_API_KEY": "your-api-key"
      }
    }
  }
}

Cursor

Open Settings → MCP and add a new server:

{
  "mcpServers": {
    "testrail": {
      "command": "npx",
      "args": ["-y", "@uarlouski/testrail-mcp-server@latest"],
      "env": {
        "TESTRAIL_INSTANCE_URL": "https://your-instance.testrail.io",
        "TESTRAIL_USERNAME": "your@email.com",
        "TESTRAIL_API_KEY": "your-api-key"
      }
    }
  }
}

Windsurf

Add to your Windsurf MCP configuration:

{
  "mcpServers": {
    "testrail": {
      "command": "npx",
      "args": ["-y", "@uarlouski/testrail-mcp-server@latest"],
      "env": {
        "TESTRAIL_INSTANCE_URL": "https://your-instance.testrail.io",
        "TESTRAIL_USERNAME": "your@email.com",
        "TESTRAIL_API_KEY": "your-api-key"
      }
    }
  }
}

Other MCP Clients

Any MCP-compliant client can use this server. The configuration pattern is the same — point it at the npx command with the required environment variables.

3. Start Using It

Once configured, ask your AI assistant things like:

"List all projects in TestRail"
"Show me the test cases in suite 1 of project 3"
"Create a test case for login validation with steps"
"Start a new test run with cases from section 5"
"Mark test 42 as passed with a comment"
