Overview

Masquerade MCP is a specialized tool that provides privacy protection for Large Language Models by acting as a data redaction layer. It processes PDF files to automatically detect and redact sensitive information such as names, emails, dates, and entities before the document is sent to an LLM. The tool integrates with Tinfoil AI platform for sensitive data detection and creates redacted versions of documents while providing users with preview capabilities and summaries of what was redacted.

Try asking AI

After installing, here are 3 things you can ask your AI assistant:

you:Processing legal contracts with sensitive client information before AI analysis
you:Redacting personal health information from medical records before LLM review
you:Protecting confidential business data in internal documents when using AI assistants

When to choose this

Choose Masquerade when working with sensitive PDF documents that need AI analysis but cannot have raw personal information exposed to LLMs.

When NOT to choose this

Don't choose Masquerade if you need to process document formats other than PDFs or if you're concerned about dependency on the Tinfoil service.
