The Problem

LLMs are great at reasoning. They're terrible at math.

Ask any AI assistant to compute 17% of 4,847 and you'll get a confident, wrong answer. Ask it to validate an email with regex, generate a SHA-256 hash, or convert timezones — same story. LLMs hallucinate on deterministic tasks.

TinyFn is a Model Context Protocol (MCP) server that gives your AI assistant 500+ tools that always return the correct answer. Math, conversions, validations, hashing, date arithmetic — the boring stuff, done right.

TinyFn in action — your agent sucks at counting

🧮 500+ Tools
_{Math, strings, dates,
and much more}

🎯 Zero Hallucinations
_{Deterministic results
every single time}

⚡ No Installation
_{Remote MCP server
zero setup}

🔌 Works Everywhere
_{Claude, Cursor, Windsurf,
any MCP client}

🖥️ Works With Your Tools

TinyFn runs as a remote MCP server — no npx, no Docker, no local install. Just add the URL to your config.

Platform	Tool Limit	Recommended Setup	Config Location
Claude Code	500+ (Tool Search)	`/mcp/all/` — use everything	`~/.claude/settings.json`
Claude Desktop	~100 tools	2–3 category servers	`~/Library/Application Support/Claude/claude_desktop_config.json`
Cursor	~40 tools	1–2 focused servers	Cursor MCP settings
Windsurf	~40 tools	1–2 focused servers	Windsurf MCP settings
Continue.dev	Varies	Category servers	`.continue/config.json`
Any MCP Client	Varies	Match to your tool limit	Client-specific

💡 Why category servers? Most AI clients limit the number of tools. TinyFn splits 500+ tools across 12 focused servers so you can pick exactly what you need.

✅ Example Queries That Just Work

Once connected, just ask your AI assistant in plain language:

Math & Numbers

✅ "Is 7919 a prime number?"
✅ *"W
