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 0 of 91 checks got a reply (0.0%), average response time 10 ms. The bar chart above shows every period we have measured.
The registry lists Sentiment Analyzer API as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
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.
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.
