Formats Social Security Numbers into the standard XXX-XX-XXXX format from raw digits or other formats. Call via MCP in Cursor or other AI coding tools, or use the REST endpoint `/v1/format/ssn`. Input "123456789" returns "123-45-6789". Handles validation and consistent output formatting for forms, databases, and user interfaces.
curl "https://tinyfn.io/v1/format/ssn" \

headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);import requests

print(data)Connect your AI agent (Claude, Cursor, Windsurf, etc.) to TinyFn's formatting tools:
{
"mcpServers": {
"tinyfn-format": {
"url": "https://tinyfn.io/mcp/format",
"headers": {
"X-API-Key": "YOUR_API_KEY"
}
}
}
}Use the Format SSN tool in your MCP-enabled editor like Cursor or Claude Code. Pass the 9-digit number as input and it returns the standard XXX-XX-XXXX format.
Accepts 9-digit strings, numbers with spaces, dots, or existing dashes. Invalid inputs with wrong digit counts or non-numeric characters will return an error.
No, it only formats valid 9-digit sequences into XXX-XX-XXXX format. It doesn't verify against Social Security Administration records or check for reserved number ranges.
The endpoint processes one SSN per request. For batch processing, make multiple calls to `/v1/format/ssn` or use the MCP tool iteratively in your AI coding environment.
The tool standardizes the format regardless of input style. "123-45-6789", "123 45 6789", or "123456789" all return the same "123-45-6789" output.
