README

Masquerade MCP: Redact. Replace. Retain Control.

🤐 Problem: Tools like Claude or GPT are incredibly powerful, but they require raw input. If you're dealing with contracts, medical records, or internal documents, that's risky.

🛡️ Solution: Masquerade acts as a privacy firewall for your files. Just paste in the file path to a PDF, and Masquerade will:

Automatically detect sensitive data (names, emails, dates, entities)
Redact the sensitive data
Let you preview before sending to an LLM

Architecture

User Input: The user asks Claude to redact a PDF by providing its file path.
PDF Processing: MCP reads the PDF and converts it to text.
Sensitive Data Detection: The text is sent to Tinfoil (an isolated AI platform using Llama 3.3 70B) to identify sensitive data.
Redaction: MCP removes the sensitive data and creates a redacted PDF.
Summary Return: MCP sends Claude a summary with:
- Masked versions of the sensitive data
- Redaction counts per page
- The path to the redacted file
Quering PDF with Claude: The user can upload the redacted PDF to Claude if satisfied with the redactions.

Installation

Install Claude desktop
Get Tinfoil API key (create account and API key)
Configure environment

Option 1: Automated

curl -O https://raw.githubusercontent.com/postralai/masquerade/main/setup.sh && bash setup.sh

Restart Claude desktop app (if successfully configured)

Option 2: Manual (click to expand)

Create a virtual environment with Python ">=3.10, <=3.12"

python3.12 -m venv pdfmcp
source pdfmcp/bin/activate
python --version

Install this repo with the command below

pip install git+https://github.com/postralai/masquerade@main

Automate the Claude config setup (and skip the next steps)

python -m masquerade.configure_claude

Get Python path: which python
Get MCP file path: python -c "import masquerade as m; print(f'{m.__path__[0]}/mcp_pdf_redaction.py')"
Add (1) Python path, (2) MCP file path, and (3) Tinfoil API key to the JSON below and add that to claude_desktop_config.json. Instructions to find the config file are in the image below.
Restart Claude

{
  "mcpServers": {
    "pdf-redaction": {
      "command": "/path/to/python", // Run `which python`
      "args": ["/path/to/mcp_pdf_redaction.py"], // Run `python -c "import masquerade as m; print(f'{m.__path__[0]}/mcp_pdf_redaction.py')"`
      "env": {
        "TINFOIL_API_KEY": "your_api_key" // Create Tinfoil account and paste API key
      }
    }
  }
}

How to use?

Prompt Claude: "Redact sensitive information from this PDF: /path/to/filename.pdf"
MCP opens the redacted and highlighted PDF files
Manually upload the redacted PDF to Claude for quering

Note: Don't upload the original PDF to Claude, only the file path.
