Tools & Capabilities Breakdown
Guardian Engine Tools (7)
verify_recipe
Verify a candidate recipe against a Guardian master spec. Returns a structured report with a strict `PASSED`/`FAILED` verdict (no scores) and detailed findings, each citing the rule it violated. The verdict is policy-driven: any `CRITICAL` finding fails the recipe; more than 5 `WARNING`s also fail.
fix_recipe
Deterministically repair a candidate recipe against a master spec. Verifies, applies every machine-actionable patch the symbolic engine produced (missing ingredients, quantities, temperatures, durations, cooking media, substitutions), then re-verifies. **No LLM is involved** — the repair is a deter…
list_dishes
List all master recipes Guardian can verify against, with rich metadata (slug, title, cuisine, region, aliases, complexity).
get_master
Return the canonical master recipe for a dish — a pure knowledge-base lookup, no LLM. Enables **compare-then-verify** loops: fetch the master, diff it against your recipe, then call `verify_recipe` instead of verifying blind. Master content is transparent by default: exact temperatures, timings, an…
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Guardian Engine is categorized under Developer Tools and uses a remote streaming HTTP/SSE transport. In contrast, Hub MCP belongs to Developer Tools using remote streaming HTTP/SSE transport. Select Guardian Engine when you need capabilities focused on developer tools and Hub MCP when you require tools for developer tools.
Master-independent safety checks for **any** recipe — no dish resolution or master spec required. Checks poultry internal-temperature safety (≥ 74 °C) and scans all ingredients against the 14 EU FIC 1169/2011 Annex II allergen groups. Use it when `verify_recipe` has no matching master.
check_allergens
Check an ingredient list for EU FIC 1169/2011 allergen presence, with a detailed audit trace mapping each ingredient to its Annex II allergen group (entry numbers and labels included).
verify_dietary_claim
Verify that a recipe satisfies a dietary claim, returning a structured verdict with the specific offending ingredients — never a vague paraphrase.
