Chainlink Sentinel

AI-powered cross-chain risk monitor using Chainlink Data Feeds. Reads on-chain oracle data across 6 EVM chains, detects anomalies in real-time, and generates actionable risk intelligence — all as MCP tools for AI agents.

What it does

• Cross-chain oracle scanning: Reads 30+ Chainlink price feeds across Ethereum, Polygon, Arbitrum, Base, Avalanche, and BNB Chain

• Anomaly detection: Identifies stale oracles, stablecoin depegs, cross-chain price deviations, and potential oracle attacks

• Risk reports: Generates comprehensive risk assessments with severity scoring, chain health metrics, and recommendations

• Zero config: No API keys needed. Uses Chainlink's on-chain data via public RPCs

Built with Chainlink

MCP Tools (6)

Quick Start

# Install
npm install

# Build
npm run build

# Run as MCP server
npm start

Use with Claude Code

Add to ~/.claude/claude_desktop_config.json:

{
  "mcpServers": {
    "chainlink-sentinel": {
      "command": "node",
      "args": ["/path/to/chainlink-sentinel/dist/index.js"]
    }
  }
}

Then ask Claude: "Run a cross-chain sentinel scan" or "Check stablecoin pegs"

Convergence Hackathon

Track: CRE & AI / Risk & Compliance

Why Chainlink Sentinel matters:

1. DeFi protocols need real-time oracle health monitoring

2. Cross-chain deviations signal arbitrage or attacks

3. Stablecoin depeg detection prevents cascading liquidations

4. AI agents can autonomously act on risk intelligence

Differentiation:

• First MCP-native Chainlink monitoring tool

• Works with any AI agent (Claude, Cursor, Windsurf)

• Zero API keys — reads directly from on-chain Chainlink contracts

• Cross-chain by default — not single-chain monitoring
