Sentiment Evolution Tracker – MCP Monitoring Stack

Sentiment Evolution Tracker is an enterprise-ready monitoring stack that runs as a Model Context Protocol (MCP) server. It combines local sentiment analytics, churn prediction, alerting, and reporting, and can operate standalone or alongside Claude Desktop as an intelligent assistant.

Why This Exists

Traditional "use Claude once and move on" workflows do not keep historical context, trigger alerts, or generate portfolio-level insights. Sentiment Evolution Tracker solves that by providing:

• Automated trend detection (RISING / DECLINING / STABLE)
• Churn probability scoring with configurable thresholds
• Persistent customer histories in SQLite
• Real-time alerts when risk exceeds 70%
• ASCII and HTML visualizations for demos and stakeholders
• Seven MCP tools that Claude (or any MCP-compatible LLM) can invoke on demand

🎥 Demo Video

A demo video (3-4 minutes) showing live sentiment analysis, risk detection, and MCP integration with Claude:

The video demonstrates:

• Live sentiment analysis of customer conversations
• Risk detection and churn prediction
• MCP tool invocation via Claude Desktop
• Real-time alerts and reporting

How to Use

Quick Start (5 minutes)

1. Clone and install:

   git clone https://github.com/RubenReyesss/mcp-nlp-analytics.git
   cd mcp-nlp-server
   pip install -r requirements.txt
   python -m textblob.download_corpora
   python -m nltk.downloader punkt averaged_perceptron_tagger
   

2. Populate demo data:

   python init_db.py
   python tools/populate_demo_data.py
   

3. View dashboard:

   python tools/dashboard.py
   

4. Generate HTML report:

   python tools/generate_report.py
   # Opens data/reporte_clientes.html in your browser
   

5. Integrate with Claude Desktop:

   • Edit config/claude_desktop_config.json with your actual path
   • Restart Claude Desktop
   • Start the MCP server: python src/mcp_server.py
   • Now Claude can access all 7 sentiment analysis tools

Installation

cd mcp-nlp-server
pip install -r requirements.txt
python -m textblob.download_corpora
python -m nltk.downloader punkt averaged_perceptron_tagger

Daily Operations

• python init_db.py – rebuilds the database from scratch (reset option)
• python tools\populate_demo_data.py – loads deterministic demo customers
• python tools\dashboard.py – terminal dashboard (Ctrl+C to exit)
• python tools\generate_report.py – creates data/reporte_clientes.html
• python src\mcp_server.py – launch the MCP server for Claude Desktop

MCP Tool Suite

Tool	Purpose
analyze_sentiment_evolution	Calculates sentiment trajectory for a set of messages
detect_risk_signals	Flags phrases that correlate with churn or dissatisfaction
predict_next_action	Forecasts CHURN / ESCALATION / RESOLUTION outcomes
get_customer_history	Retrieves full timeline, sentiment, and alerts for a customer
get_high_risk_customers	Returns customers whose churn risk is above a threshold
get_database_statistics	Portfolio-level KPIs (customers, alerts, sentiment mean)
save_analysis	Persists a custom analysis entry with full metadata

Data Model (SQLite)

• customer_profiles – customer metadata, lifetime sentiment, churn risk, timestamps
• conversations – every analysis entry, trend, predicted action, confidence
• risk_alerts – generated alerts with severity, notes, and resolution state

Database files live in data/sentiment_analysis.db; scripts automatically create the directory if needed.

Claude Desktop Integration

config/claude_desktop_config.json registers the server:

{
  "mcpServers": {
    "sentiment-tracker": {
      "command": "python",
      "args": ["src/mcp_server.py"],
      "cwd": "C:/Users/Ruben Reyes/Desktop/MCP_1stHF/mcp-nlp-server"
    }
  }
}

Restart Claude Desktop after editing the file. Once connected, the seven tools above appear automatically and can be invoked using natural language prompts.

Status

• ✅ Production-style folder layout
• ✅ Deterministic demo dataset for the hackathon video
• ✅ Comprehensive English documentation
• ✅ Tests for the save_analysis workflow (tests/test_save_analysis.py)
• ✅ Technical deep dive with NLP explanations and architecture diagrams

Run python tools\dashboard.py or open the generated HTML report to verify data before your demo, then start the MCP server and launch Claude Desktop to show the agentic workflow in real time.

Track

This project is submitted to Track 1: Building MCPs (building-mcp-track-01).

It demonstrates a production-ready MCP server that extends Claude's capabilities with persistent analytics, risk prediction, and alerting—solving the limitation that Claude lacks memory, database writes, and automated monitoring.
