Swiss Truth MCP

Verified knowledge infrastructure for AI agents — certified facts, not hallucinations.

MCP Domains Claims Languages EU AI Act Auth LangChain CrewAI AutoGen

Swiss Truth is a human + AI validated knowledge base purpose-built for AI agents. Every fact passes a 5-stage validation pipeline, carries a confidence score, verified source URLs, and a SHA256 integrity hash. Connect in 30 seconds. No API key required.

Why agents use Swiss Truth

Problem	Swiss Truth Tool
🧠 LLM hallucination on factual questions	`search_knowledge` — 2000+ certified facts, 30 domains
📎 Cannot cite sources or verify citations	`get_citations` — inline + APA with verified URLs
⏰ Stale training data on fast-changing topics	`check_freshness` — detect outdated facts
⚖️ Non-compliant responses in regulated domains	`check_regulatory_compliance` — FINMA, BAG, GDPR, EU AI Act
✅ Verify multiple claims before sending a response	`verify_claims_batch` — up to 20 claims in parallel
🔍 Full response hallucination risk	`verify_response` — low / medium / high risk score

Quick Setup

    "swiss-truth": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://swisstruth.org/mcp"]

    }
  }
}

LangChain

pip install swiss-truth-langchain

from swiss_truth_langchain import SwissTruthToolkit

toolkit = SwissTruthToolkit()
tools = toolkit.get_tools()  # search, verify, batch verify, citations, freshness, compliance

CrewAI

pip install swiss-truth-crewai

from swiss_truth_crewai import SwissTruthSearchTool, SwissTruthVerifyTool
from crewai import Agent

researcher = Agent(
    role="Research Agent",
    tools=[SwissTruthSearchTool(), SwissTruthVerifyTool()]
)

AutoGen

pip install swiss-truth-autogen

from swiss_truth_autogen import register_swiss_truth_functions

register_swiss_truth_functions(assistant, user_proxy)
# Adds: search_knowledge, verify_claim, verify_claims_batch, get_knowledge_brief

OpenAI function-calling

import requests

tools = requests.get("https://swisstruth.org/openai-tools.json").json()
# Ready-to-use tool definitions for OpenAI API, LlamaIndex, etc.
