String Utilities

Reverse String

Reverses any string character by character, handling Unicode properly. Use via MCP in Cursor or Windsurf, or call GET /v1/string/reverse with your text. Perfect for palindrome checks, text processing pipelines, or when AI agents need reliable string manipulation. Returns the exact reverse without encoding issues.

API Endpoint

GET /v1/string/reverse

Code Examples

curl "https://tinyfn.io/v1/string/reverse" \
  -H "X-API-Key: YOUR_API_KEY"

const response = await fetch('https://tinyfn.io/v1/string/reverse', {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);

import requests

response = requests.get('https://tinyfn.io/v1/string/reverse',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

Use via MCP

Add to your AI agent

Connect your AI agent (Claude, Cursor, Windsurf, etc.) to TinyFn's string tools:

{
  "mcpServers": {
    "tinyfn-string": {
      "url": "https://tinyfn.io/mcp/string",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

FAQ

How do I reverse a string using the TinyFn API?

Send a GET request to /v1/string/reverse with your string as a parameter. The API returns the reversed string with proper Unicode handling.

Does the reverse function handle Unicode characters correctly?

Yes, it properly reverses Unicode characters including emojis and multi-byte sequences, unlike naive character-by-character approaches that can break encoding.

Can I use string reverse in MCP-enabled editors like Cursor?

Absolutely. AI agents in Cursor, Windsurf, and other MCP tools can call this function directly for reliable string reversal in code generation or text processing.

What's the difference between this and JavaScript's split().reverse().join()?

TinyFn's implementation handles Unicode grapheme clusters correctly, while JavaScript's array method can split multi-byte characters incorrectly.

Is there a length limit for strings I can reverse?

The API handles reasonable string lengths efficiently. For extremely large strings, consider chunking or streaming approaches in your application.
