Sentiment Analyzer API

br0ski777/sentiment-analyzer-x402

This is a paid sentiment analysis service that runs at $402 USDC and connects via SSE transport to a remote API endpoint. The repository itself is sparse, just configuration files and workflow setup, so you're essentially buying access to a hosted NLP service rather than running something locally. It promises sentiment scoring, emotion detection, confidence metrics, and key phrase extraction, which suggests it's wrapping a commercial text analysis API. You'd reach for this if you need Claude to evaluate customer feedback, social media posts, or survey responses and you're willing to pay for the convenience of not managing your own NLP infrastructure. The x402 pricing model is unusual for MCP servers, most of which are free and open source.
