Generates cryptographically random strings with customizable length and character sets. Access via MCP in Cursor or Windsurf, or GET /v1/generate/random/string. Perfect for creating API keys, passwords, or unique identifiers. Returns truly random output using secure entropy sources, not pseudorandom algorithms.
curl "https://tinyfn.io/v1/generate/random/string" \

print(data)Connect your AI agent (Claude, Cursor, Windsurf, etc.) to TinyFn's generator tools:
{
"mcpServers": {
"tinyfn-generator": {
"url": "https://tinyfn.io/mcp/generator",
"headers": {
"X-API-Key": "YOUR_API_KEY"
}
}
}
}Specify character sets in your request (alphanumeric, symbols, etc.). The tool supports custom character pools and excludes ambiguous characters by default for readability.
Yes, request multiple strings in a single call. Useful for bulk API key generation or creating test data sets in AI-powered development workflows.
This uses cryptographically secure random generation, while most language built-ins use pseudorandom algorithms. Critical for security-sensitive applications like password generation.
Connect TinyFn's MCP server and call the random string tool directly. Your AI assistant gets deterministic random strings instead of hallucinating fake ones.
Practical limits depend on your use case, but the tool handles reasonable lengths for most applications. Very long strings may hit API response size limits.
