TestCollab MCP Server

Connect your AI coding assistant to TestCollab — manage test cases, test plans, and suites directly from Claude, Cursor, Windsurf, Codex, or any MCP-compatible client.

Quick Start

1. Get your API token

Log in to TestCollab → My Profile Settings → API Token tab → Generate new API token.

2. Add the server to your MCP client

Claude Code — add to .mcp.json in your project root:

{
  "mcpServers": {
    "testcollab": {
      "command": "npx",
      "args": ["-y", "@testcollab/mcp-server"],
      "env": {
        "TC_API_TOKEN": "your-api-token",
        "TC_API_URL": "https://api.testcollab.io",
        "TC_DEFAULT_PROJECT": "16"
      }
    }
  }
}

Claude Desktop — add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "testcollab": {
      "command": "npx",
      "args": ["-y", "@testcollab/mcp-server"],
      "env": {
        "TC_API_TOKEN": "your-api-token",
        "TC_API_URL": "https://api.testcollab.io",
        "TC_DEFAULT_PROJECT": "16"
      }
    }
  }
}

Codex - register TestCollab from the command line:

codex mcp add testcollab \
  --env TC_API_TOKEN=your-api-token \
  --env TC_API_URL=https://api.testcollab.io \
  --env TC_DEFAULT_PROJECT=16 \
  -- npx -y @testcollab/mcp-server

Or add the server to ~/.codex/config.toml for all projects, or .codex/config.toml in a trusted project:

[mcp_servers.testcollab]
command = "npx"
args = ["-y", "@testcollab/mcp-server"]

[mcp_servers.testcollab.env]
TC_API_TOKEN = "your-api-token"
TC_API_URL = "https://api.testcollab.io"
TC_DEFAULT_PROJECT = "16"

Run codex mcp list to confirm the server is configured. See the official Codex MCP documentation for configuration scopes and additional options.

Cursor — add to .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "testcollab": {
      "command": "npx",
      "args": ["-y", "@testcollab/mcp-server"],
      "env": {
        "TC_API_TOKEN": "your-api-token",
        "TC_API_URL": "https://api.testcollab.io",
        "TC_DEFAULT_PROJECT": "16"
      }
    }
  }
}

Manual Testing

TC_API_TOKEN=your-token npm start

Available Tools

list_test_cases

List test cases from a project with optional filtering.

Parameters:

3. Verify

Restart your client, then ask: "What tools do you have for TestCollab?"

You should see the TestCollab tools listed. Try: "Show me all test cases".

Configuration

EU region: If your TestCollab account is hosted in the EU, use https://api-eu.testcollab.io as your TC_API_URL.

What You Can Do

Example Prompts

"Show me all high-priority test cases in the Login suite"

"Create a test case for verifying password reset with 5 steps"

"List all test plans created this week"

"Create a regression test plan with all test cases tagged 'smoke'"

"Move the Payment suite under the Checkout suite"

See Use Cases for detailed workflows.

Local Development Setup

If you're contributing or want to run from source instead of npx:

git clone <repo-url>
cd tc-mcp-server
npm install
npm run build

Then point your MCP client to the built file:

{
  "mcpServers": {
    "testcollab": {
      "command": "node",
      "args": ["/path/to/tc-mcp-server/dist/index.js"],
      "env": {
        "TC_API_TOKEN": "your-api-token",
        "TC_API_URL": "http://localhost:1337",
        "TC_DEFAULT_PROJECT": "16"
      }
    }
  }
}

Dev Commands

npm run dev          # Watch mode with hot reload
npm run build        # Compile TypeScript
npm test             # Run tests
npm run typecheck    # Type check
npm run lint         # Lint

Troubleshooting

Server not appearing in your client

• Restart the client after adding the config
• Verify Node.js 20+ is installed: node --version
• Test manually: TC_API_TOKEN=your-token npx @testcollab/mcp-server

Authentication errors

• Verify your API token is valid and not expired
• Check that TC_API_URL points to the correct server

"project_id is required" error

• Set TC_DEFAULT_PROJECT in your env config, or
• Specify the project in your prompt: "Show me test cases in project 16"
