借助 Open Food Facts 数据，为包装食品和饮料给出 0-100 健康评分，并解读标签与添加剂。
Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/io.github.kjagsadvisors%2Ffoodchecker/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。

}An open-source food label checker for ChatGPT and Claude. Ask "is this healthy?" with a barcode, a product name or a photo of the label. You get a 0-100 score with the reasons, the way Yuka or Oasis would show it, but inside your chat and with a scoring method anyone can read.
[Score card for Coca-Cola: 15/100, Bad]
How the score is built: docs/METHODOLOGY.md.
One MCP server serves both assistants. ChatGPT and Claude both implement the open MCP Apps standard, so the same score card renders inline in each of them:
All tools are read-only and need no login.
A public instance runs at https://foodchecker-ebon.vercel.app/mcp. Paste that URL into ChatGPT or Claude as shown below. You can try the score card in a browser at https://foodchecker-ebon.vercel.app.
npm test runs the scoring tests.npm run smoke calls every tool over MCP against live data while the server is running.Use the hosted URL or your own deployment. ChatGPT can't reach localhost.
https://foodchecker-ebon.vercel.app/mcp. Authentication: No authentication.To list it in the ChatGPT app directory, follow OpenAI's submission flow at platform.openai.com/plugins. FoodChecker already supports two of its requirements through environment variables:
OPENAI_APPS_CHALLENGE: the domain-verification token, served at /.well-known/openai-apps-challenge.CHATGPT_WIDGET_DOMAIN: your widget origin.You'll also need a privacy policy URL, a terms URL, test prompts and a demo video.
claude.ai or Claude Desktop: go to Customize → Connectors → Add custom connector, paste https://foodchecker-ebon.vercel.app/mcp, and choose No sign-in. The score card renders on web, desktop and mobile.
Claude Code, remote server: run claude mcp add --transport http foodchecker https://foodchecker-ebon.vercel.app/mcp.
Claude Code, local server: run claude mcp add foodchecker -- npx tsx /path/to/repo/src/stdio.ts.
Claude Code plugin with a usage skill: this repo is a plugin marketplace. It points at the hosted server. If you self-host, change the URL in plugins/foodchecker/.mcp.json. Then run:
Claude Code shows text, not the score card. The text summary carries the same information.
The server is a standard web Request → Response handler (src/app.ts), so it runs almost anywhere.
docker build -t foodchecker . && docker run -p 3000:3000 foodcheckervercel deploy. vercel.json builds the project and routes everything to api/index.js.npm run build && npm startSet OFF_USER_AGENT to FoodChecker/0.1.0 (your contact email). Open Food Facts asks every app to identify itself. See .env.example for the other settings.
Rate limits: Open Food Facts allows roughly 15 product lookups and 10 searches per minute per IP. FoodChecker caches results in memory (products for 12 hours, searches for 1 hour). For heavy traffic, load the Open Food Facts data dump into your own database.
The most useful contributions are:
src/core/additives.ts): challenge a risk level with a source, or add a missing additive and its label names in your language.src/core/ingredients.ts): label wording that gets missed. Add a test case in test/scoring.test.ts.npm run dev:host builds a small MCP Apps host on the official AppBridge. Then open /dev/host?barcode=… to check the widget the way ChatGPT and Claude embed it.
FoodChecker gives general information about packaged food. It is not medical advice.

Check a food product
Looks up a packaged food or drink in Open Food Facts (3M+ products) by barcode or by name and returns a 0-100 health score (Excellent / Good / Poor / Bad) with the reasons: nutrition (Nutri-Score), additives and their risk level, and how processed it is. For questions such as whether a product is healthy. A barcode gives the most precise match.
querybarcodecountryScore a food from its label
Scores a food from its label: the ingredient list and/or the nutrition facts, for example from a photo of the packaging or pasted text, including products that aren't in the database. Most accurate with the ingredient list exactly as printed, including E-numbers and words in brackets. Nutrition values can be per 100 g or per serving (with the serving size). Returns the same 0-100 score and reports any missing data.
brandcategoryis_drinknutritionproduct_nameingredients_textfruit_veg_percentFind healthier alternatives
Finds similar products in the same Open Food Facts category that score clearly higher than the given product, best first, each with its score.
limitbarcode必填countryExplain a food additive
Explains what a food additive is, what it does, and its risk level with sources, by E-number (E250) or name (sodium nitrite, Red 40, carrageenan).
