Perspective API Alternative: Toxicity Detection MCP Server

This MCP server gives AI agents a tool to examine text before they publish it. The tool returns six scores from 0 to 1 and a flagged value for each text:

• TOXICITY, SEVERE_TOXICITY, INSULT, PROFANITY, THREAT, IDENTITY_ATTACK

The model is the open-source Detoxify model. It is not an LLM. Thus, the same text always gets the same score. English only.

The same server is also a direct replacement for the Google Perspective API. Google stops the Perspective API on December 31, 2026.

This repository holds the data that MCP directories show. The server runs on Apify: https://apify.com/koyourmoon/perspective-api-alternative
