Essential for brand monitoring, support ticket triage, and content tone analysis. Do NOT use for summarization -- use ai_summarize_text. Do NOT use for content extraction -- use web_scrape_to_markdown. Do NOT use for text classification -- use text_classify_content.

Each result contains: sentiment, confidence, score, emotions, keyPhrases 3. averageSentiment: overall average sentiment score across all texts 4. distribution: count of positive/negative/neutral texts Example output: {"results":[{"sentiment":"positive","confidence":91,"score":0.8},{"sentiment":"negative","confidence":74,"score":-0.6}],"averageSentiment":0.1,"distribution":{"positive":1,"negative":1,"neutral":0}} Use this FOR bulk analysis of reviews, survey responses, or social media feeds.

Sentiment Analyzer API — questions

Answers built from our own checks of this server.

What can Sentiment Analyzer API do?
It exposes 2 tools, read directly from the server on our last check. Among them: text_analyze_sentiment, text_analyze_sentiment_batch. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Sentiment Analyzer API working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 32 ms. The bar chart above shows every period we have measured.
How do I connect Sentiment Analyzer API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Sentiment Analyzer API need an API key?
No. Sentiment Analyzer API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Sentiment Analyzer API?
It answers our handshake in 32 ms on average, which is faster than 99% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Sentiment Analyzer API open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
