What is ABIS?

ABIS (Adaptive Behavioral Intelligence System) monitors LLM behavioral drift in real-time. It detects when AI models silently change — shifts in tone, reasoning depth, safety calibration, or capability — even when providers don't announce updates.

This MCP server gives Claude Code native access to:

• Live drift scores across 11 major models (GPT-4o, Claude, Gemini, DeepSeek)
• 9-score behavioral scorecards (drift, coherence, entropy, alignment, and more)
• Silent version change detection — catches updates providers don't announce
• Immune threat assessment — prompt injection, coordinated attacks, organic drift
• Correction simulation — test fixes before applying them
• Compliance reporting — EU AI Act, SOC 2, and investor briefs

Backed by Patent GB2521226.7 · Built by CIJ Labs

Quick Start

One-line install (Claude Code)

/plugin install abis-drift-monitor

Manual setup

Add to your .mcp.json:

{

    "abis": {
      "type": "sse",
      "url": "https://abis-mcp-production.up.railway.app/sse"
    }
  }
}

No API key required for the Free tier. Connects to the ABIS cloud instantly.

Self-Hosted Setup

git clone https://github.com/cijlabs/abis-mcp
cd abis-mcp
npm install
cp .env.example .env
# Set ABIS_ADMIN_KEY, MCP_PRO_KEY, and RAILWAY_URL in .env
node index.js

Then add to Claude Code:

{
  "mcpServers": {
    "abis": {
      "command": "node",
      "args": ["/path/to/abis-mcp/index.js"],
      "env": {
        "ABIS_ADMIN_KEY": "your_admin_key_here"
      }
    }
  }
}
