Overview

What is Sensitive Lexicon Mcp?

Sensitive Lexicon Mcp is an MCP (Model Context Protocol) server built on the Sensitive-lexicon sensitive word library. It provides large language models (LLMs) with sensitive word detection and filtering capabilities, supporting multiple categories such as political, pornography, violence, and advertisement. It is designed for developers and users who need to moderate or redact sensitive content in AI applications.

How to use Sensitive Lexicon Mcp?

Install globally via npm install -g sensitive-lexicon-mcp or locally in a project. Configure it as an MCP server in supported clients (Claude Desktop, Continue.dev, Cline, Zed, Cursor) by adding a JSON entry with npx sensitive-lexicon-mcp. The server exposes tools like detect_sensitive_words and filter_sensitive_words that accept text and optional categories or replacement parameters. Environment variables (SENSITIVE_UPDATE_INTERVAL, SENSITIVE_CACHE_SIZE, DEBUG) allow customization.

Key features of Sensitive Lexicon Mcp

  • Detects sensitive words in any given text.
  • Filters (replaces) sensitive words with a customizable string.
  • Supports 15 categories of sensitive words (political, violence, pornography, etc.).
  • Real‑time lexicon updates fetched from a GitHub repository.
  • Standard MCP protocol for easy integration with any MCP‑compatible client.
  • Provides helper tools: get_categories and get_word_count.

Use cases of Sensitive Lexicon Mcp

  • Automatically check user‑generated content for sensitive terms before displaying it.
  • Redact sensitive words in LLM outputs before exposing them to users.
  • Integrate into CI/CD pipelines to scan code comments or documentation for sensitive language.
  • Batch‑process a large corpus of text files to flag or sanitize sensitive content.
  • Build a content moderation layer inside a custom chat application or agent.
