Troubleshooting

Issue: Tool not activating when promptedSymptoms:
  • No response to text reversal requests
  • Tools not showing in Studio
  • Commands not being recognized
Solutions:
  1. Check Server Status:
    • Go to Settings → MCP Servers → Reverse Text
    • Verify server shows as “Active” (green indicator)
    • Check for any error messages
  2. Enable the Server:
    • If disabled, click “Enable”
    • Wait for status to change to active
    • Try your prompt again
  3. Restart Server:
    • Disable the server
    • Wait 2 seconds
    • Re-enable the server
    • Test with simple prompt
  4. Be More Explicit: 
    Instead of: "flip this: Hello"
Try: "Reverse the text: Hello"
Or: "Use reverse text tool on: Hello"
  5. Restart Studio:
    • Close and reopen Studio
    • Check server is still enabled
    • Try test prompt again
Be specific in your prompt - say “reverse the text” rather than just asking about the text.
Issue: Output doesn’t match expectationsCommon scenarios:1. Getting JSON Instead of Plain Text:
{
  "original_text": "Hello",
  "reversed_text": "olleH",
  "length": 5
}
Solution: This is correct! The tool returns structured data. Ask Studio to extract just the reversed text:
"Reverse 'Hello' and show me only the reversed version"
2. Spaces Not Where Expected:
  • Spaces ARE included in reversal
  • “Hello World” → “dlroW olleH” (space reversed in place)
  • This is correct behavior
3. Case Looks Wrong:
  • Case is preserved
  • “HeLLo” → “oLLeH” (not “Olleh”)
  • Uppercase stays uppercase, lowercase stays lowercase
4. Numbers Reversed:
  • Numbers reverse like any character
  • “Test 123” → “321 tseT”
  • This is expected behavior
The tool reverses ALL characters in place, including spaces, punctuation, and numbers. This is standard text reversal behavior.
Issue: Special characters or emojis not handled as expectedWhat works well:
  • ✅ Letters (A-Z, a-z)
  • ✅ Numbers (0-9)
  • ✅ Basic punctuation (. , ! ? ; :)
  • ✅ Common symbols ($ % & @ #)
  • ✅ Spaces and tabs
What may have issues:
  • ⚠️ Emojis (may reverse incorrectly)
  • ⚠️ Complex Unicode characters
  • ⚠️ Right-to-left language text
  • ⚠️ Combined diacritical marks
  • ⚠️ Zero-width characters
Examples:Good:
"Hello, World! 123" → "321 !dlroW ,olleH"
"[email protected]" → "moc.liame@tseT"
"$100 USD" → "DSU 001$"
May be problematic:
"Hello 👋🌍" → (emoji may not reverse correctly)
"مرحبا" → (right-to-left text issues)
"café" → (diacritical marks may not work right)
Best practices:
  • Test with your specific characters first
  • Use plain ASCII for consistent results
  • For emojis, keep them separate from reversed text
  • Consider removing special characters before reversing
Most common text and punctuation work perfectly. Edge cases with complex Unicode characters may vary.
Issue: Very long text takes time or doesn’t workCharacter limits (approximate):
  • ✅ Small text: <100 characters - instant
  • ✅ Medium text: 100-1,000 characters - very fast
  • ✅ Long text: 1,000-10,000 characters - fast
  • ⚠️ Very long: 10,000+ characters - may be slow
Solutions:1. Break into chunks:
Instead of reversing a 50,000 character document:
- Process paragraph by paragraph
- Process section by section
- Combine results manually
2. Ask for help:
"Break this long text into paragraphs and reverse each one"
3. Consider if you need reversal:
  • Do you need ALL text reversed?
  • Can you reverse just key sections?
  • Would text analysis be better?
Memory considerations:
  • Server processes in memory
  • Very long text uses more resources
  • Batch processing is more efficient
For documents, process one paragraph at a time for better performance and easier management.
Issue: Studio doesn’t recognize the commandSymptoms:
  • Studio responds without using tool
  • No tool usage indicator (🔧)
  • Generic response instead of reversal
Solutions:1. Use explicit keywords:
Good prompts:
✅ "Reverse this text: [text]"
✅ "Use reverse text tool on: [text]"
✅ "Flip the characters in: [text]"
✅ "Mirror this text: [text]"

Vague prompts:
❌ "What about: [text]"
❌ "Try: [text]"
❌ "Show me: [text]"
2. Verify server is active:
  • Check MCP Servers list
  • Look for green “Active” indicator
  • Ensure it’s not disabled
3. Test with simple example:
"Reverse the text: Test"
Should return: “tseT”4. Check tool availability:
"What reverse text tools are available?"
5. Restart conversation:
  • Sometimes starting fresh helps
  • Server state resets
  • Try your prompt again
Studio’s AI is smart, but explicit prompts help ensure the right tool is used every time!
Issue: Character count doesn’t match expectationsCommon confusion:1. Spaces count as characters:
{
  "text": "Hello World",
  "character_count": 11,  // includes space
  "character_count_no_spaces": 10  // excludes space
}
2. Multiple spaces all count:
"Hello  World" has 12 characters (2 spaces)
"Hello   World" has 13 characters (3 spaces)
3. Line breaks count:
  • \n counts as 1 character
  • \r\n counts as 2 characters
  • Empty lines add to count
4. Tabs count:
  • Tab character (\t) = 1 character
  • Visual width doesn’t affect count
Different count types:
  • character_count - Total including spaces
  • character_count_no_spaces - Excludes spaces
  • length - Same as character_count
  • word_count - Space-separated words
Examples:
"Hello" → 5 characters, 1 word
"Hello World" → 11 characters, 10 without spaces, 2 words
"Hello  World" → 12 characters, 10 without spaces, 2 words
Use character_count_no_spaces when you need length without spaces, like for hashtags or usernames!

What is Text Reversal?Text reversal is the process of reversing the order of characters in text. It’s one of the simplest text transformations but has many creative applications.How it works:
Original: "Hello World"
Step 1: Split into characters: H-e-l-l-o- -W-o-r-l-d
Step 2: Reverse the order: d-l-r-o-W- -o-l-l-e-H
Result: "dlroW olleH"
Character-by-character reversal:
  • Every character moves to mirror position
  • First character becomes last
  • Last character becomes first
  • Middle stays in middle (for odd-length text)
What gets preserved:
  • Case (uppercase/lowercase)
  • Character type (letters/numbers/symbols)
  • All characters including spaces
Common Uses:
  • Creating mirror text effects
  • Simple encoding/obfuscation
  • Palindrome detection
  • Text puzzles and games
  • Creative typography
  • Algorithm testing
Text reversal is deterministic - reversing reversed text returns the original!
What are Palindromes?Palindromes are words, phrases, or sequences that read the same forwards and backwards.Word Palindromes:
  • “racecar” → “racecar”
  • “level” → “level”
  • “noon” → “noon”
  • “radar” → “radar”
  • “kayak” → “kayak”
Phrase Palindromes (ignoring spaces/punctuation):
  • “A man a plan a canal Panama”
  • “Madam, I’m Adam”
  • “Never odd or even”
  • “Do geese see God?”
  • “Was it a car or a cat I saw?”
How to check with Reverse Text:
  1. Reverse the text
  2. Compare with original
  3. If identical = palindrome!
Example:
"Reverse: racecar"
Result: "racecar"
Original = Reversed ✓ Palindrome!
Uses:
  • Word games and puzzles
  • Creative writing challenges
  • Algorithm testing
  • Language learning
  • Mathematics (palindromic numbers)
Use the reverse tool to quickly verify if text is palindromic - if original equals reversed, it’s a palindrome!

Character Count Types Explained:1. Total Character Count:
  • Includes everything
  • Spaces, tabs, line breaks
  • Punctuation and symbols
  • This is what platforms limit
2. Character Count (No Spaces):
  • Excludes all whitespace
  • Spaces, tabs, line breaks removed
  • Only visible characters
  • Useful for dense text metrics
3. Word Count:
  • Space-separated segments
  • “Hello World” = 2 words
  • Multiple spaces still count as separator
  • Standard metric for content length
4. Character Type Counts:
  • Uppercase letters (A-Z)
  • Lowercase letters (a-z)
  • Digits (0-9)
  • Everything else is punctuation/symbols
Examples:
"Hello World!"
- Total: 12 characters
- No spaces: 11 characters
- Words: 2
- Uppercase: 2 (H, W)
- Lowercase: 8 (e,l,l,o,o,r,l,d)
- Digits: 0

"Test 123"
- Total: 8 characters
- No spaces: 7 characters
- Words: 2
- Uppercase: 1 (T)
- Lowercase: 3 (e,s,t)
- Digits: 3 (1,2,3)
