MCP Conceal
by gbrigandi
Privacy-focused MCP proxy that pseudo-anonymizes PII in real-time to protect sensitive data before it reaches AI providers.
What it does
MCP Conceal acts as a privacy-preserving proxy for MCP servers. It intelligently detects and pseudo-anonymizes Personally Identifiable Information (PII) in real-time. Unlike simple redaction, it replaces sensitive data with realistic fake equivalents, maintaining semantic relationships and data structures so that AI models can still perform accurate analysis without seeing the actual private data.
Tools
This is a proxy server; it does not expose its own functional tools but instead wraps other MCP servers, adding a PII detection and anonymization layer to their responses.
Installation
To use MCP Conceal as a proxy for another server, add it to your claude_desktop_config.json:
{
"mcpServers": {
"concealed-server": {
"command": "mcp-server-conceal",
"args": [
"--target-command", "python3",
"--target-args", "your-server.py",
"--config", "/path/to/mcp-server-conceal.toml"
]
}
}
}
