Testrail MCP Server

🚀 TestRail MCP Server

Connect Claude, Cursor, Windsurf, and VS Code to TestRail — an open-source Model Context Protocol (MCP) server for AI-assisted test management.

Manage TestRail projects, search and create test cases, kick off test runs, record results, and attach files through natural-language conversation with your AI assistant — or from CI/CD with the bundled testrail-cli . Built for QA engineers and AI-assisted test automation.

What is the TestRail MCP Server?

The TestRail MCP Server is a free, open-source Model Context Protocol server that gives AI assistants direct, structured access to a TestRail instance through the TestRail API v2. Once configured, an assistant such as Claude Desktop, Cursor, Windsurf, or GitHub Copilot in VS Code can search test cases, draft new ones, start test runs, record results, and upload attachments on your behalf — without you leaving the chat window.

It exposes 35 tools, runs locally on Node.js 18+ over the MCP stdio transport, and is licensed under Apache 2.0. There is nothing to host or deploy: your MCP client launches it on demand with npx.

No context switching. No tedious copy-pasting. Just ask your AI.

[!NOTE]

Compatibility baseline: tested and validated against TestRail 10.6.2 (API v2). Older TestRail instances (including pre-7.x pagination) are also supported via built-in backward compatibility. TestRail Cloud and self-hosted TestRail Server both work.

✨ Key Features & Capabilities

🚀 Quick Start Guide

1. Obtain your TestRail API key

Navigate to My Settings → API Keys in TestRail and generate a new key. Copy it immediately — TestRail shows it only once. The API must also be enabled instance-wide under Administration → Site Settings → API.

2. Configure your MCP client

Add the server to your MCP client configuration. The Claude Desktop example is shown below; Cursor, Windsurf, and VS Code use the same pattern (see the collapsible sections).

🤖 Claude Desktop

Add this to 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", "TESTRAIL_ENABLE_SHARED_STEPS": "true" } } } }

⌨️ Cursor

Open Settings → MCP → Add new MCP server, or edit .cursor/mcp.json in your project (~/.cursor/mcp.json for all projects):

{

"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" } } } }

</details>

🌊 Windsurf

Edit ~/.codeium/windsurf/mcp_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" } } } }

</details>

💻 VS Code

Add to .vscode/mcp.json. The inputs block keeps your API key out of the file:

{

"inputs": [ { "id": "testrail-api-key", "type": "promptString", "description": "TestRail API key", "password": true } ], "servers": { "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": "${input:testrail-api-key}" } } } }

</details>

🌐 Other MCP Clients

Any MCP-compliant client can use this server, because it speaks the standard MCP stdio transport. Point your client at the npx command with the required environment variables — no port, URL, or transport configuration needed.

3. See it in action

Restart your client completely, then turbo-charge your QA workflow by asking your AI assistant:

• *"List all projects in TestRail to find the latest active project."*
• *"Show me all active users in the project to find the right assignee."*
• *"Show me all test cases in section 5 of project 3."*
• *"Create a comprehensive test case for 'Login Validation' with detailed steps."*
• *"Start a new test run containing cases from section 5."*
• *"Mark test case C1042 as passed with the comment 'verified on staging'."*

Full per-client setup instructions, including troubleshooting, are in the Getting Started guide.

🖥️ Command Line Interface (CLI) & CI/CD Automation

In addition to interacting via AI assistants, you can invoke any TestRail tool directly from shell scripts, terminal environments, and automated CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins) using `testrail-cli` or `npx` — with zero LLM overhead.

• Deterministic Execution: Returns standard Unix exit codes (0 on success, 1 on error).
• Pipeline-Native Output: Emits clean JSON to stdout for piping into tools like jq, while diagnostics and errors go to stderr.
• Zero Duplication: Reuses the exact same API client, retry logic, and validation schemas as the MCP server.

Invocation methods

# Method 1: Direct npx subcommand (Recommended)

npx @uarlouski/testrail-mcp-server cli [flags]

Method 2: Global or local binary

testrail-cli [flags]

Method 3: Via package runner

npx -p @uarlouski/testrail-mcp-server testrail-cli [flags]

Examples

Query projects (query_project)

# List all active projects

npx @uarlouski/testrail-mcp-server cli query_project --action many

Query a single project by ID

npx @uarlouski/testrail-mcp-server cli query_project --action one --project_id 1

Report automated test results (add_results_for_cases)

# Submit results by case_id — what your test framework already knows

npx @uarlouski/testrail-mcp-server cli add_results_for_cases \ --run_id 88 \ --results '[{"case_id":1042,"status_id":1,"comment":"Passed in CI"}]'

Export cases for knowledge base / RAG (export_cases_for_rag)

# Export all cases for a project into Markdown & metadata sidecars

npx @uarlouski/testrail-mcp-server cli export_cases_for_rag \ --project_id 1 \ --output_dir ./rag_exports

Export specific cases by ID (comma-separated list)

npx @uarlouski/testrail-mcp-server cli export_cases_for_rag \ --case_ids C101,C102,103 \ --output_dir ./rag_exports

Command discovery & flag documentation
