MCP Testing Framework

Comprehensive testing framework for Model Context Protocol (MCP) servers

A powerful, easy-to-use testing framework specifically designed for validating MCP server implementations. This enhanced framework dramatically simplifies MCP server testing workflows and provides comprehensive validation capabilities.

🎯 Key Features

🚀 Simplified Testing Workflow

Replace complex containerization setups with a simple one-liner:

pip install mcp-testing-framework && mcp-test --test-mcp-servers

🔧 Comprehensive Testing Suite

• Functional Testing: Validate MCP server capabilities and tool implementations
• Security Testing: Authentication, input validation, and vulnerability scanning
• Performance Testing: Load testing, resource monitoring, and bottleneck detection
• Integration Testing: End-to-end workflow validation with real LLM interactions
• Compatibility Testing: Cross-platform and multi-version validation

🎨 Multiple CLI Entry Points

• mcp-test - Primary testing interface
• mcp-testing - Alternative testing command
• mcp-client - Client interaction mode
• llm - Legacy compatibility mode

📊 Rich Reporting & Analytics

• Detailed test reports with confidence scoring
• Performance metrics and resource usage analysis
• Issue detection with automated remediation suggestions
• Export results in multiple formats (JSON, HTML, XML)

🔄 CI/CD Integration

• Ready-to-use GitHub Actions templates
• Cross-platform support (Ubuntu, macOS, Windows)
• Multiple Python version testing (3.9-3.12)
• Automated performance benchmarking

🚀 Quick Start

Installation

pip install mcp-testing-framework

Basic Usage

1. Test MCP Servers:

   mcp-test --test-mcp-servers
   

2. Run Comprehensive Test Suite:

   mcp-testing --suite-type all --output-format json
   

3. Performance Testing:

   mcp-test --performance-test --load-test-duration 300
   

Configuration

Create a configuration file ~/.llm/config.json:

{
  "systemPrompt": "You are an AI assistant helping with MCP server testing.",
  "llm": {
    "provider": "openai",
    "model": "gpt-4o-mini",
    "api_key": "your-api-key",
    "temperature": 0.7
  },
  "mcpServers": {
    "your-server": {
      "command": "node",
      "args": ["path/to/your/server.js", "--stdio"],
      "env": {
        "DEBUG": "*"
      },
      "enabled": true
    }
  }
}
