Overview

Description from the maker (original English)

Toxicity scores (0-1) for text before an agent posts it. Perspective API compatible. No LLM.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http perspective-api-alternative https://koyourmoon--perspective-api-alternative.apify.actor/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Common questions

Is Perspective API Alternative (Toxicity Detection) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.9) reached the registry 28 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Perspective API Alternative: Toxicity Detection MCP Server

This repository contains an MCP server for the stdio transport. The server gives AI agents one tool, analyze_toxicity. Use the tool to examine text before an agent publishes 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 scores come from the open-source Detoxify model. The model is not an LLM. Thus, the same text always gets the same score. English only.

The request and response format is the same as the format of the Google Perspective API. Google stops the Perspective API on December 31, 2026.

How the server operates

The server implementation is server.py in this repository. It uses only the Python standard library (Python 3.9 or later).

The server reads JSON-RPC messages from stdin and writes the responses to stdout.
The server answers initialize, ping and tools/list itself. These messages do not need a token.
For tools/call, the server sends the texts to the toxicity API on Apify, and returns the scores.
The toxicity API runs the Detoxify model. You pay for each call through your Apify account.

Requirements

Python 3.9 or later, or Docker
An Apify API token in the APIFY_TOKEN environment variable

To get a token, open the Apify Console. Then go to Settings > API & Integrations.

Installation

Python

Clone the repository:

   git clone https://github.com/koyourmoon/perspective-api-alternative-mcp.git

Add the server to the configuration of your MCP client:

"mcpServers": { "perspective-api-alternative": { "command": "python", "args": ["/path/to/perspective-api-alternative-mcp/server.py"], "env": { "APIFY_TOKEN": " " } } } }

Docker

Build the image:

   docker build -t perspective-api-alternative-mcp .

Add the server to the configuration of your MCP client:

"mcpServers": { "perspective-api-alternative": { "command": "docker", "args": ["run", "-i", "--rm", "-e", "APIFY_TOKEN", "perspective-api-alternative-mcp"], "env": { "APIFY_TOKEN": " " } } } }

Tool: analyze_toxicity

Parameter	Type	Description
`texts`	array of strings, required	1 to 100 English texts to score
`attributes`	array of strings	Attributes to return. The default is all six.
`threshold`	number	`TOXICITY` score at which a text is flagged. The default is 0.5.

Example result for one text:

"results": [ { "text": "You are an idiot.", "scores": { "TOXICITY": 0.98, "INSULT": 0.95, "PROFANITY": 0.62 }, "flagged": true, "billed_units": 1 } ] }

If a text looks non-English, the result has a warning field. The scores for that text are not reliable.

Environment variables

Name	Required	Description
`APIFY_TOKEN`	Yes, for `tools/call`	Your Apify API token
`PERSPECTIVE_ALT_URL`	No	A different URL for the toxicity API

Prices

$0.50 for 1,000 text units. A text unit is each started 1,000 characters of a text. Most comments are 1 unit.
Lower prices for Apify Bronze, Silver and Gold plans.
The first call after an idle period of 60 seconds can take 10 to 30 seconds (cold start).

Remote connection (optional)

You can also connect your MCP client directly to the toxicity API. This connection does not use server.py.

Item	Value
Transport	Streamable HTTP
URL	`https://koyourmoon--perspective-api-alternative.apify.actor/mcp`
Authentication	`Authorization: Bearer`
