Fix: Complete Apple Notes MCP server functionality fixes #2

pmdusso · 2025-10-20T15:00:02Z

Summary

This PR fixes multiple critical issues with the Apple Notes MCP server, making it fully functional.

Changes

✅ Fix AppleScript multi-line execution using multiple -e flags
✅ Redirect console output to stderr for JSON-RPC compatibility
✅ Preserve line breaks using HTML formatting
✅ Clean whitespace in all lists to prevent empty items
✅ Auto-convert nested lists to div format (Apple Notes limitation workaround)
✅ Add automatic iCloud account detection with fallback

Testing

All features tested and working:

Multi-line scripts execute correctly
Line breaks are preserved in notes
Simple lists render without empty items
Nested lists are automatically converted to formatted divs
Account detection works with fallback to default

Fixes

Resolves syntax errors when executing multi-line AppleScript commands and improves overall reliability.

+        // Build formatted output
+        converted += `<div><b><font color=\\"#0066CC\\">${mainItemCounter}. ${mainText}</font></b></div>`;


The mainText variable is inserted directly into HTML without sanitization. If the text contains HTML special characters or malicious content, it could lead to XSS vulnerabilities or rendering issues. Consider using a sanitization function or escaping HTML entities.

The subitem variable is inserted directly into HTML without sanitization. This could lead to XSS vulnerabilities or rendering issues if the content contains HTML special characters. Consider using a sanitization function or escaping HTML entities.

+    // But be careful not to add <br> inside HTML tags
+    formatted = formatted.replace(/\n(?![^<]*>)/g, '<br>');


The negative lookahead regex /\n(?![^<]*>)/g is complex and may be difficult to maintain. Consider adding a comment explaining that this pattern matches newlines that are NOT inside HTML tags, or extracting this logic into a well-named helper function.

+  return /<li[^>]*>[\s\S]*?<(?:ul|ol)[\s>]/i.test(html);


The regex pattern [\s\S]*? in a non-capturing group can be inefficient for large HTML strings. Consider using the s (dotAll) flag with . instead: /<li[^>]*>.*?<(?:ul|ol)[\s>]/is.test(html)

Suggested change

+const hasNestedLists = (html: string): boolean => {
+  // Using dotAll flag (s) for better performance with multiline HTML
+  // The pattern matches <li> tags that contain nested <ul> or <ol> tags
+  return /<li[^>]*>.*?<(?:ul|ol)[\s>]/is.test(html);


The regex with dotAll flag (s) may have performance issues on large HTML strings due to the .*? pattern. Consider using a more specific pattern like /<li[^>]*>[^<]*<(?:ul|ol)[\s>]/i which avoids the expensive dotAll matching, or compile the regex once as a constant to avoid recreating it on every call.

Suggested change

const hasNestedLists = (html: string): boolean => {

// Using dotAll flag (s) for better performance with multiline HTML

// The pattern matches <li> tags that contain nested <ul> or <ol> tags

return /<li[^>]*>.*?<(?:ul|ol)[\s>]/is.test(html);

// Precompiled regex to detect <li> tags containing nested <ul> or <ol> tags, avoiding dotAll and .*?

const NESTED_LIST_REGEX = /<li[^>]*>[^<]*<(?:ul|ol)[\s>]/i;

const hasNestedLists = (html: string): boolean => {

return NESTED_LIST_REGEX.test(html);

src/services/appleNotesManager.ts

+    // Regex explanation: \n(?![^<]*>)
+    // - \n: Match a newline character
+    // - (?!...): Negative lookahead - only match if NOT followed by...
+    // - [^<]*: Any number of non-'<' characters
+    // - >: Followed by a closing '>'
+    // This ensures we don't add <br> inside HTML tag attributes or between tag delimiters
+    formatted = formatted.replace(/\n(?![^<]*>)/g, '<br>');


The regex pattern /\n(?![^<]*>)/g will incorrectly add <br> tags inside HTML tag attributes. For example, in <div title=\"line1\nline2\">, the newline is not followed by <, so the negative lookahead succeeds and adds <br>. Consider using a more robust HTML-aware approach or a pattern that properly handles tag boundaries.

Regex has endless concerns, but we gotta deal with it. @pmdusso, if you are interested to address the review comments.

Sure thing @Siddhant-K-code give me a day or two.
