Mcp Server

Arkheia MCP Server — Fabrication Detection for AI Agents

Know when your AI is making things up.

Arkheia screens model responses for fabrication using behavioural fingerprinting. Works with Claude, GPT, Gemini, Grok, Llama, Mistral, and 30+ other models. One tool call. Real-time risk scoring.

Free tier: 1,500 detections/month. No credit card.

Install

npx @arkheia/mcp-server

The installer sets up a Python environment, clones the server, and configures everything. Takes about 60 seconds.

You'll need:

• Node.js 18+
• Python 3.10+
• An API key (free — see below)

Get an API Key

curl -X POST https://arkheia-proxy-production.up.railway.app/v1/provision \
  -H "Content-Type: application/json" \
  -d '{"email": "you@example.com"}'

Save the key. You won't see it again.
