Guardian Engine — API & MCP Integration Guide

Deterministic verification infrastructure for AI agent outputs. Guardian Engine catches hallucinated temperatures, missing techniques, wrong ingredients, and impossible cooking steps before they reach the pan. Recipes are the first vertical — the same deterministic approach generalises to any procedural domain where correctness matters.

Endpoint: https://api.kaimeilabs.dev/mcp
Transport: Streamable HTTP (MCP)
Auth: None — free during early access (fair use applies)

⚠️ Safety & Liability Notice

Guardian Engine is an automated, informational recipe-verification tool. It is not a food-safety, medical, nutritional, or regulatory-compliance authority, and its output is not professional advice.

• Allergens are not guaranteed. Allergen warnings come from an automated knowledge base that may be incomplete or wrong. A PASSED verdict is NOT a guarantee that a recipe is free of any allergen or safe for any individual. Never rely on Guardian to decide whether a food is safe for someone with a food allergy or intolerance — always verify against the actual ingredient/product labelling and consult a qualified professional.
• Cooking-safety findings are informational and must not replace certified guidance (e.g. USDA, EU FIC, or your local food-safety authority).
• No warranty. The Service is provided "AS IS", without warranty of any kind. To the maximum extent permitted by law, Kaimei Labs accepts no liability for any loss, injury, or damage arising from use of, or reliance on, Guardian output.

Use of the API constitutes acceptance of the full Terms of Service (warranty disclaimer, limitation of liability, indemnification).

Connect Your Agent

Guardian is a hosted MCP server. No install, no API key, no Docker. Pick your client and paste the config.

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "guardian": {
      "url": "https://api.kaimeilabs.dev/mcp",
      "transport": "streamable-http"
    }
  }
}

Restart Claude Desktop. Ask: "List the available dishes in Guardian Engine" to confirm.

Cursor

Open Settings → MCP Servers → Add new MCP server, then paste:

{
  "guardian": {
    "url": "https://api.kaimeilabs.dev/mcp",
    "transport": "streamable-http"
  }
}

VS Code (GitHub Copilot)

Add to your .vscode/mcp.json (or user settings.json under "mcp"):

{
  "servers": {
    "guardian": {
      "type": "http",
      "url": "https://api.kaimeilabs.dev/mcp"
    }
  }
}

Windsurf

Add to your Windsurf MCP config:

{
  "mcpServers": {
    "guardian": {
      "serverUrl": "https://api.kaimeilabs.dev/mcp"
    }
  }
}

Smithery (One-Click)

— auto-configures Claude Desktop, Cursor, and more.

[!WARNING] Smithery Proxy Limitation: The default Smithery proxy URL (guardian-engine--kaimeilabs.run.tools) does not support Streaming HTTP and will silently fail. You MUST edit your MCP config after installation to use the direct endpoint: https://api.kaimeilabs.dev/mcp.

Glama.ai

Guardian Engine is also listed on Glama.ai — discover and connect to MCP servers from the Glama directory.

Any MCP Client (Python SDK)

import asyncio
from mcp.client.session import ClientSession
from mcp.client.streamable_http import streamable_http_client
from httpx import AsyncClient

async def main():
    async with AsyncClient(timeout=30.0) as http:
        async with streamable_http_client("https://api.kaimeilabs.dev/mcp", http_client=http) as streams:
            read_stream, write_stream, _ = streams
            async with ClientSession(read_stream, write_stream) as session:
                await session.initialize()
                result = await session.call_tool("list_dishes", arguments={"cuisine_filter": "french"})
                print(result)

asyncio.run(main())

pip install mcp>=1.2.1 httpx>=0.27.0

Tools

verify_recipe

Verify a candidate recipe against a Guardian master recipe. Returns a structured report with a PASSED/FAILED verdict and detailed findings (each citing the rule it violated).

Parameter	Type	Required	Description
dish	string	Yes	Name or alias of the dish (e.g. "carbonara", "rendang", "kung-pao", "bourguignon")
candidate_json	string	Yes	Full recipe as a JSON string — see schema.md
original_prompt	string	No	The user's original request that generated the recipe
response_format	string	No	"text" (default) or "json". Use "json" for machine-actionable patches in agentic self-correction loops

Tip — include the original prompt for personalised feedback: When you include original_prompt (e.g. "Make a spicy vegan rendang"), Guardian matches findings to the user's stated dietary needs and flavour preferences (e.g. flagging which specific issue conflicts with a "vegan" or "spicy" intent), and activates audience-sensitive safety checks (e.g. flagging honey in recipes for infants, raw egg for pregnant users). Without it, Guardian still returns the full verdict and all findings.

list_dishes

List all master recipes Guardian can verify against.

Parameter	Type	Required	Description
cuisine_filter	string	No	Filter by cuisine (e.g. "french", "chinese", "thai")

Missing a Dish?

The catalog is regularly expanding. If your agent requires verification for a dish not currently supported, please open an issue on GitHub to request it. We prioritize additions based on developer demand.

Example Verification Output

What does a Guardian verification report actually look like? Here's the response structure when an AI agent submits a recipe with authenticity issues:

{
  "verdict": "FAILED",
  "response_format_version": "v3",
  "findings": [
    {
      "issue": "MISSING_REQUIRED_INGREDIENT",
      "severity": "CRITICAL",
      "justification": "This ingredient provides a signature flavour component essential to the dish's identity."
    },
    {
      "issue": "WRONG_COOKING_MEDIUM",
      "severity": "WARNING",
      "justification": "Cooking medium fundamentally affects texture and flavour."
    }
  ],
  "allergen_warnings": ["milk", "eggs"],
  "summary": {"INFO": 1, "WARNING": 1, "CRITICAL": 2}
}

Each finding includes a severity and a justification grounded in culinary science — letting the agent fix only what's wrong instead of guessing.

Data & Privacy

• No PII collected — we do not store user names, emails, or API keys. Underlying cloud infrastructure may temporarily process IP addresses for routing.
• Data for Compute Exchange — the free service is provided in exchange for usage data. Submitted recipes are used to improve verification accuracy and create anonymized derived datasets. See our Terms of Service.
• Do not include PII in recipe payloads.
• Fair use quotas enforced via compute limits.

[!CAUTION] Not a Substitute for Food Safety Knowledge
While Guardian Engine catches explicitly dangerous AI hallucinations (like serving poultry below safe temperatures), it cannot guarantee a recipe is 100% safe to consume. Pathogen destruction relies on variables (time, mass, equipment) that text-based AI models cannot perfectly control. Verification results are informational and must always be paired with human common sense and standard kitchen safety practices.
