## ✨ Features

- **📥 Input Support**: Swagger/OpenAPI documents and Postman collections
- **🔄 Test Generation**: Automatic API and Load test scenario generation
- **⚡ Test Execution**: Run generated tests with detailed reporting
- **🔐 Authentication**: Bearer token and API key support via `set_env_vars`

- **📈 Real-time Progress**: Live updates during test execution
- **✅ Schema Validation**: Request body generation from schema examples
- **🎯 Assertions**: Per-endpoint status code assertions (2xx, 4xx, 5xx)

## 🛠️ MCP Tools

The server provides 7 comprehensive MCP tools:

1. **`ingest_spec`** - Load Swagger/OpenAPI or Postman collections
2. **`set_env_vars`** - Configure authentication and environment variables
3. **`generate_scenarios`** - Create test scenarios from specifications
4. **`generate_test_cases`** - Convert scenarios to executable test cases
5. **`run_api_tests`** - Execute API tests with detailed results
6. **`run_load_tests`** - Execute performance/load tests
7. **`get_session_status`** - Retrieve current session information

## 📚 MCP Resources

- **`file://reports`** - List all available test reports
- **`file://reports/{report_id}`** - Access individual HTML test reports

## 💡 MCP Prompts

- **`create_api_test_plan`** - Generate comprehensive API test plans
- **`analyze_test_failures`** - Analyze test failures and provide recommendations

## 🔧 Configuration Example

```javascript
// Set environment variables for authentication
await mcp.call("set_env_vars", {
  variables: {
    "baseUrl": "https://api.example.com",
    "auth_bearer": "your-bearer-token",
    "auth_apikey": "your-api-key"
  }
});

// Ingest an OpenAPI specification
await mcp.call("ingest_spec", {
  spec_type: "openapi",
  content: openapi_json_string
});

// Generate test scenarios
await mcp.call("generate_scenarios", {
  include_negative_tests: true,
  include_edge_cases: true
});

// Run API tests
await mcp.call("run_api_tests", {
  max_concurrent: 5
});
```

## � Complete Workflow Example

Here's a complete example of testing the Petstore API:

```bash
# 1. Start the MCP server
npx @kirti676/api-tester-mcp@latest
```

Then in your MCP client (like Claude Desktop):

```javascript
// 1. Load the Petstore OpenAPI spec
await mcp.call("ingest_spec", {
  kind: "openapi", 
  path_or_text: "https://petstore.swagger.io/v2/swagger.json"
});

// 2. Set environment variables
await mcp.call("set_env_vars", {
  pairs: {
    "baseUrl": "https://petstore.swagger.io/v2",
    "auth_apikey": "special-key"
  }
});

// 3. Generate test cases
const tests = await mcp.call("get_generated_tests");

// 4. Run API tests
const result = await mcp.call("run_api_tests");

// 5. View results in HTML report
const reports = await mcp.call("list_resources", {
  uri: "file://reports"
});
```

## �📖 Usage Examples

### Basic API Testing Workflow

1. **Ingest API Specification**
   ```json
   {
     "tool": "ingest_spec",
     "params": {
       "spec_type": "openapi",
       "content": "{ ... your OpenAPI spec ... }"
     }
   }
   ```

2. **Configure Authentication**
   ```json
   {
     "tool": "set_env_vars", 
     "params": {
       "variables": {
         "auth_bearer": "your-token",
         "baseUrl": "https://api.example.com"
       }
     }
   }
   ```

3. **Generate and Run Tests**
   ```json
   {
     "tool": "generate_scenarios",
     "params": {
       "include_negative_tests": true
     }
   }
   ```

4. **View Results**
   - Access HTML reports via MCP resources
   - Get session status and statistics

### Load Testing

```json
{
  "tool": "run_load_tests",
  "params": {
    "users": 10,
    "duration": 60,
    "ramp_up": 10
  }
}
```

## 🔍 Test Generation Features

- **Positive Tests**: Valid requests with expected 2xx responses
- **Negative Tests**: Invalid authentication (401), wrong methods (405)
- **Edge Cases**: Large payloads, boundary conditions
- **Schema-based Bodies**: Automatic request body generation from OpenAPI schemas
- **Comprehensive Assertions**: Status codes, response times, content validation

## 📊 HTML Reports

Generated reports include:
- Test execution summary with pass/fail statistics
- Detailed test results with timing information
- Assertion breakdowns and error details
- Response previews and debugging information
- Mobile-friendly responsive design

## 🔒 Authentication Support

- **Bearer Tokens**: `auth_bearer` environment variable
- **API Keys**: `auth_apikey` environment variable (sent as X-API-Key header)
- **Basic Auth**: `auth_basic` environment variable

## 🔧 Requirements

- **Python**: 3.8 or higher
- **Node.js**: 14 or higher (for npm installation)

## 📦 Dependencies

## 🔧 Troubleshooting

### Common Issues

**NPX Command Not Working**
```bash
# If npx command fails, try:
npm install -g @kirti676/api-tester-mcp@latest

# Or run directly:
node ./node_modules/@kirti676/api-tester-mcp/cli.js
```

**Python Not Found**
```bash
# Make sure Python 3.8+ is installed and in PATH
python --version

# Install Python dependencies manually if needed:
pip install fastmcp>=0.2.0 pydantic>=2.0.0 requests>=2.28.0
```

**MCP Client Connection Issues**
- Ensure the MCP server is running on stdio transport (default)
- Check that your MCP client supports the latest MCP protocol version
- Verify the configuration JSON syntax is correct
