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.

  What this check looks for
Description, as the server wrote it
Converts a kitchen amount between volume and weight for a specific ingredient, using measured grams-per-cup values (USDA FoodData Central portion weights with FDC ids, and the King Arthur Baking ingredient weight chart) instead of guessed densities. 271 ingredients. Units: US cup (236.5882365 mL), metric cup (250 mL), imperial cup, US legal cup (240 mL), Japanese cup, US/metric/Australian tablespoons, teaspoons, US and imperial fl oz, pints, quarts, gallons, mL, dL, L, g, mg, kg, oz, lb and sticks of butter. Volume to volume and weight to weight need no ingredient. States which cup definition it used and cites the density source.

  What this check looks for
Description, as the server wrote it
Converts an oven setting between Fahrenheit, Celsius and UK gas mark (1/4 to 10, from the standard recipe table) and optionally adjusts for a fan (convection) oven by 20 C, the manufacturer guidance. Returns the nearest gas mark and whether it is an exact table value.

scale_recipeScales a list of recipe ingredient lines ("1 1/2 cups all-purpose flour", "2 tbsp honey", "3 eggs") by a factor or from original to target servings.No findings
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
Scales a list of recipe ingredient lines ("1 1/2 cups all-purpose flour", "2 tbsp honey", "3 eggs") by a factor or from original to target servings. Parses mixed numbers and fraction characters. With to_metric_weights, converts cup and spoon amounts to grams with the measured density table and weights to grams, and reports lines it could not match.

- readOnlyHint: true
- destructiveHint: false

Description, as the server wrote it
Fuzzy search over the ingredient table (flours, sugars, fats, dairy, liquids, nuts, grains, fruit, produce). Returns canonical names, grams per US cup and per tablespoon, and the source (USDA FDC id or King Arthur Baking chart). Use it to pick the exact ingredient before converting.

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 untrusted-input or outbound.

Reads private data1: Reads files, mail, messages, databases, secrets, calendars or repositories.; search_ingredients
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.

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 cups-to-grams. Review it before you use it.
