Feature Request: Add Save to File for take_snapshot and evaluate_script tools

Is your feature request related to a problem? Please describe.
I am unable to save off screenshots using the chrome-devtools-mcp server. Sometimes I also get too many token errors on tool results.

Describe the solution you'd like
Add a save to file optional parameter to tools that return images (take_screenshot) or large amounts of data (take_snapshot, evaluate_script) .

The mcp-chrome server (and several others) supports saving images as files using the asPng optional parameter.

From the mcp-chrome server:

{
    name: TOOL_NAMES.BROWSER.SCREENSHOT,
    description:
      'Take a screenshot of the current page or a specific element(if you want to see the page, recommend to use chrome_get_web_content first)',
    inputSchema: {
      type: 'object',
      properties: {
        name: { type: 'string', description: 'Name for the screenshot, if saving as PNG' },
        selector: { type: 'string', description: 'CSS selector for element to screenshot' },
        width: { type: 'number', description: 'Width in pixels (default: 800)' },
        height: { type: 'number', description: 'Height in pixels (default: 600)' },
        storeBase64: {
          type: 'boolean',
          description:
            'return screenshot in base64 format (default: false) if you want to see the page, recommend set this to be true',
        },
        fullPage: {
          type: 'boolean',
          description: 'Store screenshot of the entire page (default: true)',
        },
        savePng: {
          type: 'boolean',
          description:
            'Save screenshot as PNG file (default: true)，if you want to see the page, recommend set this to be false, and set storeBase64 to be true',
        },
      },
      required: [],
    },
  },

Describe alternatives you've considered
Claude code can't (or won't) let me save the [Image] data returned from the tool call to take_screenshot...

Additional context
The mcp-chrome server (and others) also support returning images as base 64 content using the storeBase64 optional parameter.

Start by locating the take_screenshot, take_snapshot, and evaluate_script tool entry points. Define optional file-saving behavior for image and large-data results, then verify that each tool can return a saved-file result without exceeding tool-result limits.
