Signal Agent 🚨

Intelligent Failure Event Processing via Model Context Protocol (MCP)

A production-ready MCP server and client system that transforms raw failure events into actionable intelligence through automated classification, severity analysis, and response recommendations.

MCP Protocol Python Transport

🎯 What is Signal Agent?

Signal Agent demonstrates the power of the Model Context Protocol (MCP) for building intelligent automation systems. It processes failure events through a sophisticated analysis pipeline that:

  • 🔍 Analyzes failure event content using keyword-based severity assessment
  • 📊 Classifies events into operational categories (database, network, security, etc.)
  • 💡 Generates appropriate response recommendations
  • 📋 Formats human-readable summaries for operational teams

✨ Key Features

🏗️ Production-Ready Architecture

  • Standards-compliant MCP implementation using official SDK
  • Robust input validation with Pydantic schemas
  • Comprehensive error handling and logging
  • Transport-agnostic design (stdio for development, HTTP streamable for production)

🧠 Intelligent Analysis Pipeline

  • Multi-stage event processing with validation and enrichment
  • Keyword-based severity recalculation independent of source assessment
  • Operational classification for proper incident routing
  • Contextual recommendations based on severity and event type

🔧 Developer Experience

  • Multiple deployment modes (integrated demo, server-only, agent-only)
  • MCP Inspector compatibility for interactive testing
  • Comprehensive logging and debugging support
  • Clear separation of concerns between transport and business logic

🚀 Quick Start

Prerequisites

  • Python 3.8+
  • uv (modern Python package manager)
  • just

Installation

git clone https://github.com/no0ktheali3n/signal-agent.git
cd signal-agent

Server Tools

classify_failure_event

Processes failure events through intelligent analysis pipeline.

Input Schema:

{
  "event_id": "string",
  "timestamp": "string", 
  "service": "string",
  "severity": "string",
  "message": "string",
  "details": "object (optional)"
}

Example Usage:

{
  "event_id": "sig_001_db_failure",
  "timestamp": "2024-12-11T14:30:45Z",
  "service": "user-authentication-service",
  "severity": "critical",
  "message": "PostgreSQL connection pool exhausted",
  "details": {
    "pool_size": 20,
    "active_connections": 20,
    "queue_length": 150
  }
}

Response:

{
  "event_id": "sig_001_db_failure",
  "original_severity": "critical",
  "calculated_severity": "critical",
  "classification": "database_issue",
  "recommendation": "Immediate attention required - escalate to on-call engineer",
  "human_readable": "🚨 Signal Alert: sig_001_db_failure...",
  "status": "processed"
}
health_check

Server health and connectivity verification.

Testing with MCP Inspector

# In another terminal, launch MCP Inspector
npx @modelcontextprotocol/inspector uv run python server/server.py

or

just run-inspector

Testing HTTP Transport

# Terminal 1: Start HTTP server
just run-server-http

# Terminal 2: Test with HTTP agent
just run-agent-http

# Or test with direct commands
python main.py server --transport http
python main.py agent --transport http

The inspector will provide a web interface at http://localhost:#### for interactive tool testing.
