gsfa_check_use

Answer whether a specific food additive is permitted in a specific food category under the Codex General Standard for Food Additives, and at what maximum level. Returns the maximum use level (a numeric limit such as 10,000 mg/kg, or GMP meaning good manufacturing practice), which GSFA table the perm

gsfa_search_additive

Find food additives in the Codex GSFA by INS number, name, or synonym. Returns each match with its INS number, name, synonyms, technological functional classes (thickener, preservative, colour, and so on), and how many food-category provisions it holds. Use to resolve an additive name or E-number to

gsfa_additive_provisions

List every food category in which a given food additive is permitted under the Codex GSFA, with the maximum use level for each. Separates Table 1 and 2 provisions (which carry a specific maximum level) from Table 3 provisions (permitted under good manufacturing practice with no numeric limit). Use t

gsfa_food_category_additives

List every food additive permitted in a given Codex GSFA food category, with each maximum use level. Includes provisions inherited from parent categories, since a GSFA provision applies to a category and all of its subcategories. Use to see what additives may legally be used in a particular food.

gsfa_search_food_categories

Search the Codex GSFA food category system by number or name — for example "cheese", "beverages", or "01.4". Returns matching category numbers and names. Use to find the right GSFA food category number before checking which additives are permitted in it.

gsfa_notes

Look up the qualifying notes that condition Codex GSFA food additive provisions. GSFA provisions are frequently limited by numbered notes such as "for use in ready-to-drink products only", "as sulphur dioxide", or "on the fat basis", and a maximum use level is not fully specified without them. Give

gsfa_coverage

Report what this Codex GSFA dataset contains and how current it is: the Codex Alimentarius Commission sessions represented, counts of additives, food categories and provisions, and which additive records could not be retrieved. Use to check the freshness and completeness of GSFA answers before relyi

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

7/7 tools missing one or more hints — gsfa_check_use (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gsfa_search_additive (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gsfa_additive_provisions (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tests exist

No test files found

Add tests that exercise each declared tool.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
