Redact MCP for LangChain

io.github.r3352/redact-mcp

Auto-detects and obfuscates PII (IPs, emails, API keys, names) so Claude never sees real client data

client:LangChain transport:stdio runtime:npm

Install Redact MCP in LangChain

pip install langchain-mcp-adapters 

from langchain_mcp_adapters.client import MultiServerMCPClient

client = MultiServerMCPClient({
        "redact-mcp": {
            "transport": "stdio",
            "command": "npx",
            "args": ["-y", "@mattzam/redact-mcp"],
        }
})

tools = await client.get_tools()

get_tools() returns the server's tools as LangChain tools, ready for an agent. LangChain docs
