Which integrations are available for this server?

Enables calling Google Gemini models with integrated fabrication screening to detect and score potential hallucination risks in the generated output. Enables calling local Ollama models with integrated fabrication screening to detect and score potential hallucination risks in the generated output.

Arkheia MCP Server — Fabrication Detection for LLMs

Detect fabrication (hallucination) in any LLM output. Free tier included (1,500 detections/month).

Quick Start

1. Clone and install

git clone https://github.com/arkheiaai/arkheia-mcp.git ~/.arkheia-mcp
cd ~/.arkheia-mcp
pip install -r requirements.txt

2. Get an API key (free)

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

3. Add to Claude Desktop

Edit your config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "arkheia": {
      "command": "python",
      "args": ["-m", "mcp_server.server"],
      "cwd": "~/.arkheia-mcp",
      "env": {
        "PYTHONPATH": "~/.arkheia-mcp",
        "ARKHEIA_API_KEY": "ak_live_YOUR_KEY_HERE"
      }
    }
  }
}

On Windows, replace ~/.arkheia-mcp with the full path (e.g. C:/Users/YourName/.arkheia-mcp).

4. Restart Claude

The arkheia_verify and arkheia_audit_log tools will appear automatically.
