Determines if text reads the same forwards and backwards, ignoring case, spaces, and punctuation. Use via MCP in Cursor or Windsurf, or call GET /v1/string/is-palindrome with your text. Returns true for "A man a plan a canal Panama" and false for "hello world". Perfect for form validation and text processing in AI workflows.

print(data)Connect your AI agent (Claude, Cursor, Windsurf, etc.) to TinyFn's string tools:
{
"mcpServers": {

"headers": {
"X-API-Key": "YOUR_API_KEY"
}

}The tool ignores whitespace, punctuation, and case when checking. 'A man, a plan, a canal: Panama!' returns true because only alphanumeric characters are compared.
Yes, it works with any Unicode text including accented characters, emojis, and non-Latin scripts. The comparison is character-based regardless of language.
This provides deterministic results without implementation bugs. AI agents get reliable answers instead of potentially flawed generated code, especially useful for edge cases with Unicode.
In Cursor or Claude Code, your AI agent can call this tool directly to validate user input or process text data. No need to write and debug palindrome logic.
Returns a boolean result indicating whether the text is a palindrome. The response is structured for easy parsing in both MCP tools and REST API calls.
