Start the MCP server\nnpx @kirti676/api-tester-mcp@latest\n```\n\nThen in your MCP client (like Claude Desktop):\n\n```javascript\n// 1. Load the Petstore OpenAPI spec\nawait mcp.call(\"ingest_spec\", {\n  spec_type: \"openapi\",\n  file_path: \"./examples/petstore_openapi.json\"\n});\n\n// 2. Set environment variables\nawait mcp.call(\"set_env_vars\", {\n  pairs: {\n    \"baseUrl\": \"https://petstore.swagger.io/v2\",\n    \"auth_apikey\": \"special-key\"\n  }\n});\n\n// 3. Generate test cases\nconst tests = await mcp.call(\"get_generated_tests\");\n\n// 4. Run API tests\nconst result = await mcp.call(\"run_api_tests\");\n\n// 5. View results in HTML report\nconst reports = await mcp.call(\"list_resources\", {\n  uri: \"file://reports\"\n});\n```\n\n## \ud83d\udcd6 Usage Examples\n\n### \ud83d\udd04 Basic API Testing Workflow\n\n1. **\ud83d\udce5 Ingest API Specification**\n   ```json\n   {\n     \"tool\": \"ingest_spec\",\n     \"params\": {\n       \"spec_type\": \"openapi\",\n       \"content\": \"{ ... your OpenAPI spec ... }\"\n     }\n   }\n   ```\n\n2. **\ud83d\udd10 Configure Authentication**\n   ```json\n   {\n     \"tool\": \"set_env_vars\", \n     \"params\": {\n       \"variables\": {\n         \"auth_bearer\": \"your-token\",\n         \"baseUrl\": \"https://api.example.com\"\n       }\n     }\n   }\n   ```\n\n3. **\ud83d\ude80 Generate and Run Tests**\n   ```json\n   {\n     \"tool\": \"generate_scenarios\",\n     \"params\": {\n       \"include_negative_tests\": true\n     }\n   }\n   ```\n\n4. **\ud83d\udcca View Results**\n   - \ud83d\udcc4 Access HTML reports via MCP resources\n   - \ud83d\udcc8 Get session status and statistics\n\n### \u26a1 Load Testing\n\n```json\n{\n  \"tool\": \"run_load_tests\",\n  \"params\": {\n    \"users\": 10,\n    \"duration\": 60,\n    \"ramp_up\": 10\n  }\n}\n```\n\n## \ud83d\udd0d Test Generation Features\n\n- **\u2705 Positive Tests**: Valid requests with expected 2xx responses\n- **\u274c Negative Tests**: Invalid authentication (401), wrong methods (405)\n- **\ud83c\udfaf Edge Cases**: Large payloads, boundary conditions\n- **\ud83c\udfd7\ufe0f Schema-based Bodies**: Automatic request body generation from OpenAPI schemas\n- **\ud83d\udd0d Comprehensive Assertions**: Status codes, response times, content validation\n\n## \ud83d\udcca HTML Reports\n\nGenerated reports include:\n- \ud83d\udcc8 Test execution summary with pass/fail statistics\n- \u23f1\ufe0f Detailed test results with timing information\n- \ud83d\udd0d Assertion breakdowns and error details\n- \ud83d\udc41\ufe0f Response previews and debugging information\n- \ud83d\udcf1 Mobile-friendly responsive design\n\n## \ud83d\udd12 Authentication Support\n\n- **\ud83c\udfab Bearer Tokens**: `auth_bearer` environment variable\n- **\ud83d\udd11 API Keys**: `auth_apikey` environment variable (sent as X-API-Key header)\n- **\ud83d\udc64 Basic Auth**: `auth_basic` environment variable\n\n## \ud83d\udd27 Requirements\n\n- **\ud83d\udc0d Python**: 3.8 or higher\n- **\ud83d\udfe2 Node.js**: 14 or higher (for npm installation)\n\n## \ud83d\udce6 Dependencies\n\n### \ud83d\udc0d Python Dependencies\n- \ud83d\ude80 fastmcp>=0.2.0\n- \ud83d\udcca pydantic>=2.0.0\n- \ud83c\udf10 requests>=2.28.0\n- \u2705 jsonschema>=4.0.0\n- \ud83d\udcdd pyyaml>=6.0\n- \ud83c\udfa8 jinja2>=3.1.0\n- \ud83d\udcc1 aiofiles>=23.0.0\n- \u26a1 aiohttp>=3.8.0\n- \ud83c\udfad faker>=19.0.0\n\n### \ud83d\udfe2 Node.js Dependencies  \n- \u2728 None (self-contained package)\n\n## \ud83d\udd27 Troubleshooting\n\n### \u2757 Common Issues\n\n**\ud83d\udce6 NPX Command Not Working**\n```bash\n# If npx command fails, try:\nnpm install -g @kirti676/api-tester-mcp@latest\n\n# Or run directly:\nnode ./node_modules/@kirti676/api-tester-mcp/cli.js\n```\n\n**\ud83d\udc0d Python Not Found**\n```bash\n# Make sure Python 3.8+ is installed and in PATH\npython --version\n\n# Install Python dependencies manually if needed:\npip install fastmcp>=0.2.0 pydantic>=2.0.0 requests>=2.28.0\n```\n\n**\ud83d\udd17 MCP Client Connection Issues**\n- \u2705 Ensure the MCP server is running on stdio transport (default)\n- \ud83d\udd04 Check that your MCP client supports the latest MCP protocol version\n- \ud83d\udcdd Verify the configuration JSON syntax is correct\n\n### \ud83c\udd98 Getting Help\n\n1. \ud83d\udcd6 Check the [Examples](examples/) directory for working configurations\n2. \ud83d\udd0d Run with `--verbose` flag for detailed logging\n3. \ud83d\udc1b Report issues on [GitHub Issues](https://github.com/kirti676/api_tester_mcp/issues)\n\n## \ud83e\udd1d Contributing\n\n1.
