安全提示

MCP 服務會接收對話中的工具呼叫請求，並可能執行外部操作。啟用前請先了解該服務能做什麼，並只授予它所需的權限。

註冊中心已驗證此服務的命名空間屬於 tinyfn.io，且該網域同時執行其端點。這可以確認發布者，但並不代表該服務的工具是安全的。

SourceWeft 的檢查只涵蓋條目是否完整、端點是否回應；不審查伺服器的程式碼，也不審查其工具的行為。

概覽

AI 產生的概覽

TinyFn 是遠端 MCP 伺服器，為助理提供 500 多個確定性工具，涵蓋數學、單位換算、驗證、雜湊、編碼、日期與統計。

可以做什麼: 檢查與計算數字：質數、奇偶、階乘、費氏數列、最大公因數與最小公倍數、次方、開根號、對數、三角函數、取整與區間限制，以及基本四則運算和清單的最小值、最大值、平均值。換算單位與格式：溫度、長度、重量、體積、速度、資料大小、進位制和顏色值。驗證輸入：電子郵件、網址、電話、信用卡號、UUID、IP、JSON、日期、十六進位和 Base64。雜湊與編碼：MD5、SHA-256/512、SHA-3、BLAKE2、HMAC、CRC32、Base64、URL、HTML、十六進位、JWT 解碼、ROT13 和摩斯電碼。處理日期與統計：日期解析、日期差、時區轉換、閏年，以及平均數、中位數、眾數、變異數、百分位數和相關性。產生內容：UUID、密碼、權杖、隨機數與隨機字串、骰子、擲硬幣和打亂清單。
適用情境: 適合助理需要給出精確算術結果、單位或顏色換算、格式驗證、雜湊、編碼或日期計算，而不是靠估算的時候，特別是在程式開發、資料分析、維運和內容創作流程中。
執行需求: 使用 api.tinyfn.io 的遠端端點，不需本機安裝。需要 TinyFn API 金鑰，透過 X-API-Key 標頭傳送，可在廠商網站免費取得。工具有數量上限的用戶端可改用依類別劃分的端點，且網址必須以斜線結尾。需要網路連線。

安裝前請注意

每次呼叫都會送到第三方服務並計入配額：免費方案每月 100 次請求、每分鐘 10 次，更高用量需付費。API 金鑰屬於機密，應避免寫入共用設定。雜湊、編碼和 JWT 工具會把送出的文字傳到遠端伺服器，請勿送出金鑰或敏感資料。

安裝

在 SourceWeft 中

開啟儀表板中的 TinyFn，將其新增到工作區。
連接 X-API-Key 憑證。它們會被私密儲存，絕不會在公開頁面上展示。
為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.tinyfn%2Ftinyfn/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

[TinyFn — 500+ Deterministic Tools for AI Agents]

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]

🖥️ 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?"
✅ "What's 17% of 4,847?"
✅ "Calculate the factorial of 12"

Conversions

✅ "Convert 72°F to Celsius"
✅ "How many miles is 100 kilometers?"
✅ "Convert #3B82F6 to RGB values"

Validation

✅ "Is [email protected] a valid email address?"
✅ "Validate this credit card number: 4111111111111111"
✅ "Is 550e8400-e29b-41d4-a716-446655440000 a valid UUID?"

Encoding & Hashing

✅ "Base64 encode 'Hello, World!'"
✅ "Generate a SHA-256 hash of 'my-secret-string'"
✅ "URL encode 'hello world & goodbye'"

Date & Time

✅ "How many days between January 15 and March 22?"
✅ "What's the current Unix timestamp?"
✅ "Is 2024 a leap year?"

Generators

✅ "Generate a UUID"
✅ "Create a secure 20-character password"
✅ "Roll 3 six-sided dice"

⚡ Quick Start

1. Get your free API key at tinyfn.io (takes 10 seconds)

2. Add TinyFn to your MCP client:

Claude Code

Claude Code supports Tool Search, so you can use the full server with all 500+ tools:

json

{  "mcpServers": {    "tinyfn": {      "url": "https://api.tinyfn.io/mcp/all/",      "headers": {        "X-API-Key": "tf_live_YOUR_KEY_HERE"      }    }  }}

{  "mcpServers": {    "tinyfn": {      "url": "https://api.tinyfn.io/mcp/all/",      "headers": {        "X-API-Key": "tf_live_YOUR_KEY_HERE"      }    }  }}

Add this to ~/.claude/settings.json or use claude mcp add.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

json

{  "mcpServers": {    "tinyfn-math": {      "url": "https://api.tinyfn.io/mcp/math/",      "headers": {        "X-API-Key": "tf_live_YOUR_KEY_HERE"      }    },    "tinyfn-validate": {      "url": "https://api.tinyfn.io/mcp/validate/",      "headers": {        "X-API-Key": "tf_live_YOUR_KEY_HERE"      }    }  }}

{  "mcpServers": {    "tinyfn-math": {      "url": "https://api.tinyfn.io/mcp/math/",      "headers": {        "X-API-Key": "tf_live_YOUR_KEY_HERE"      }    },    "tinyfn-validate": {      "url": "https://api.tinyfn.io/mcp/validate/",      "headers": {        "X-API-Key": "tf_live_YOUR_KEY_HERE"      }    }  }}

Tip: Claude Desktop supports ~100 tools. Add 2–3 category servers based on your workflow.

Cursor & Windsurf

These platforms have a ~40 tool limit. Pick 1–2 focused servers:

json

{  "mcpServers": {    "tinyfn-validate": {      "url": "https://api.tinyfn.io/mcp/validate/",      "headers": {        "X-API-Key": "tf_live_YOUR_KEY_HERE"      }    }  }}

{  "mcpServers": {    "tinyfn-validate": {      "url": "https://api.tinyfn.io/mcp/validate/",      "headers": {        "X-API-Key": "tf_live_YOUR_KEY_HERE"      }    }  }}

Recommended for Cursor/Windsurf: validate (15 tools), hash (18 tools), encode (20 tools), convert (42 tools).

Continue.dev

json

{  "experimental": {    "mcpServers": [      {        "name": "tinyfn-math",        "url": "https://api.tinyfn.io/mcp/math/",        "headers": {          "X-API-Key": "tf_live_YOUR_KEY_HERE"        }      }    ]  }}

{  "experimental": {    "mcpServers": [      {        "name": "tinyfn-math",        "url": "https://api.tinyfn.io/mcp/math/",        "headers": {          "X-API-Key": "tf_live_YOUR_KEY_HERE"        }      }    ]  }}

🔧 Troubleshooting

❌ Getting 404 errors

All MCP server URLs must end with a trailing slash /.

❌ Authentication errors (401/403)

Verify your API key starts with tf_live_
Check that you're using the X-API-Key header (not Authorization)
Make sure your key is active at tinyfn.io/dashboard

❌ Too many tools / client not loading

Your MCP client has a tool limit. Instead of /mcp/all/, use category-specific servers:

See the full server list for all options.

❌ Rate limit exceeded (429)

You've hit your plan's rate limit. Options:

Free tier: 10 requests/minute, 100/month — upgrade at tinyfn.io
Starter: 100 requests/minute, 10,000/month
