[BUG] Limited Testing Coverage

[Limeload]

Current testing is minimal with only basic connection tests. No integration tests for MCP tools or database operations.

Missing Tests:

• MCP tool integration tests
• Database operation tests
• Authentication flow tests
• Error handling tests
• Performance tests

Expected Implementation:

// tests/mcp-tools.test.ts
describe('MCP Tools', () => {
  test('query_database tool executes queries correctly', async () => {
    const result = await mcpClient.callTool('query_database', {
      query: 'SELECT 1 as test',
      target: 'sqlite'
    });
    expect(result.content[0].text).toContain('test');
  });
});

Acceptance Criteria:

• Comprehensive test suite for MCP tools
• Database operation integration tests
• Authentication and authorization tests
• Error handling and edge case tests
• Performance and load tests
• Test coverage > 80%
