3 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it Parses ingredient lines ("2 cups flour", "1 stick butter" as 8 tbsp, "3 large eggs", "1 lb ground beef"), converts cups, spoons and counted items to grams with USDA household measure weights for that specific food, and sums USDA FoodData Central nutrients. Returns per-line grams and matches, recipe totals, per-serving values, and the per-serving values rounded by the FDA Nutrition Facts rules (21 CFR 101.9) with percent Daily Value. Lines it cannot match are listed, never guessed.

Description, as the server wrote it Applies the FDA Nutrition Facts rounding rules from 21 CFR 101.9(c) to unrounded per-serving values: calories (under 5 = 0, nearest 5 up to 50, nearest 10 above), fat and saturated fat (nearest 0.5 g under 5 g), sodium (nearest 5 mg up to 140 mg, nearest 10 above), carbohydrate, fiber, sugars, added sugars and protein (nearest gram, "less than 1g" rules). Adds percent Daily Value from the 2,000-calorie DRVs (fat 78 g, saturated fat 20 g, sodium 2,300 mg, carbohydrate 275 g, fiber 28 g, added sugars 50 g). Rules copied from the eCFR text.

Description, as the server wrote it Returns USDA FoodData Central nutrient values per 100 g (calories, protein, total fat, saturated fat, carbohydrate, fiber, total sugars, sodium) for a common recipe ingredient, with its FDC id, the USDA household measures (1 cup, 1 tbsp, 1 large, 1 clove) in grams, and optionally the nutrients for an amount such as 1.5 cup or 3 large. 406 ingredients from SR Legacy and Foundation Foods, embedded, no API key.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
The server marks "round_nutrition_label" read-only (readOnlyHint: true), and its own name, description or input give the class "write".
What this check looks forMatched text

History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__recipe-nutrition-calculator__lookup_ingredient_nutrition"
],
"ask": [

"mcp__recipe-nutrition-calculator__scale_recipe_nutrition"
],
"deny": []
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as recipe-nutrition-calculator. Review it before you use it.
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
