ABIS MCP Server

AI Behavioral Drift Monitoring for Claude Code

37 tools · 11 models · 3 tiers · Real-time drift detection · Patent-backed

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

Quick Start

One-line install (Claude Code)

/plugin install abis-drift-monitor

Manual setup

Add to your .mcp.json:

{
  "mcpServers": {
    "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.

Free Tier (15 tools)

Pro Tier (+12 tools)

Admin Tier (+10 tools)

Included Skills

After installing, you get two built-in skills:

• /abis-ops — Daily health check: drift snapshot, version changes, stability ranking, cost summary
• /abis-alerts — Investigate a drift alert: scorecard deep-dive, CAS trends, threat classification, correction recommendation

Models Monitored

Try It

"What is the current drift score for GPT-4o?"
"Run ABIS daily check"
"Has Claude Sonnet drifted in the last 7 days?"
"Generate an EU AI Act compliance report"
"Which model is most stable right now?"
"Have any models had silent version updates this week?"
"Show me the cost vs drift matrix"

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"
      }
    }
  }
}

• Dual transport: SSE (HTTP for cloud) + stdio (Claude Desktop/Code)
• Rate limiting: 60 req/min global; per-tier limits (free=30, pro=120, admin=300)
• Backend: Proxies to ABIS FastAPI on Railway
• Persistence: MongoDB Atlas (sessions, scores, conversations, benchmarks)
