Sentor AI MCP Server — entity-based sentiment analysis tools for Claude, Cursor, and any MCP-compatible AI assistant

Sentor MCP Server

Connect Sentor's entity-based sentiment analysis to Claude, Cursor, Windsurf, and any MCP-compatible AI assistant.

What It Does

Once installed, your AI assistant gains four tools:

Tool	What it does
analyze_sentiment	Score sentiment toward specific entities in any text
cluster_documents	Group 5+ documents by topic automatically (BERTopic)
name_topic	Generate a 3-5 word label for each cluster using LLM
health_check	Verify Sentor API is reachable

Example prompt after setup: "Analyze these 50 customer reviews for sentiment toward our checkout flow and shipping speed, then cluster them by topic."

Requirements

• Python 3.10+
• A Sentor API key → Get one free at dashboard.sentor.app

Installation

pip install sentor-mcp

Usage Examples

Once connected, use natural language:

Sentiment analysis:

"Use Sentor to analyze the sentiment of these reviews toward Apple and iPhone: [paste reviews]"

Clustering:

"I have 200 customer support tickets. Use Sentor to cluster them by topic and name each cluster."

Full pipeline:

"Analyze sentiment in these 100 reviews for 'delivery' and 'packaging' entities, then cluster them and name each cluster."
