Implementation Reference

• src/index.ts:272-282 (handler)

  The execution handler for the 'test_security' tool. It receives an array of tests (e.g., password-policy, rate-limiting), logs them, and returns a completion message. Note: actual security testing implementation is a placeholder comment.

  case "test_security": {
    const { tests } = request.params.arguments as { tests: string[] };
    logger.info(`Running security tests: ${tests.join(", ")}`);
    // Implementation would run security tests
    return {
      content: [{
        type: "text",
        text: `Security tests completed for: ${tests.join(", ")}`
      }]
    };
  }

• src/index.ts:151-167 (registration)

  Tool registration in the ListTools handler, defining the name, description, and input schema for 'test_security'. The schema expects an object with a 'tests' array containing specific security test names.

  {
    name: "test_security",
    description: "Run security tests on Better-Auth setup",
    inputSchema: {
      type: "object",
      properties: {
        tests: {
          type: "array",
          items: {
            type: "string",
            enum: ["password-policy", "rate-limiting", "session-management"]
          }
        }
      },
      required: ["tests"]
    }
  },
