Is your feature request related to a problem? Please describe.

As Lighthouse provides some limited automatic accessibility testing I would like to see it in the MCP as well. It is always an option to use other, specialized MCPs for accessibility needs, but I think offering Lighthouse accessibility testing results directly in Chrome DevTools MCP could be beneficial to awareness and even helping with suggestions for basic fixes.

Describe the solution you'd like

As a minimum, tools would get a section called Accessibility that would have at least two tools:

1. getting the accessibility score for a page (as per https://developer.chrome.com/docs/lighthouse/accessibility/scoring) - I am aware that scores are not representing the whole situation as per limitations of automatic tests, but it would be useful to get at least a hint that the score represents.
2. getting accessibility audit details - a list of errors and impacted code / DOM elements - so that AI can try to come with fix suggestions.

Describe alternatives you've considered

Using snapshot tool does not offer insights into automatically detected issues, so the only alternative now is to use a specialized MCP for accessibility.

Additional context

I am using/testing multiple other accessibility oriented MCPs now, but if I consider people just starting with accessibility - it would be a great start and better to have something than nothing.
