What is the Strict PII Redaction Engine MCP Server?
Sending raw legal or financial documents to LLMs risks massive data privacy breaches and compliance violations (GDPR/CCPA). Relying on an LLM to "forget" or manually scrub PII is an immense security vulnerability. This engine operates as a strict, local firewall, employing high-performance regex algorithms to deterministically eradicate emails, credit cards, SSNs, CPFs, and phone numbers. It seamlessly replaces sensitive intelligence with [REDACTED] tags locally, ensuring your client data remains entirely uncompromised before the LLM even sees the context.

Instantly replaces Emails, CPFs, SSNs, and Credit Cards with [REDACTED] tags using fast offline regex

Frequently asked questions
Does it read the meaning of the text?
No, it strictly executes compiled local mathematical regex patterns, ensuring it never hallucinates or leaks contextual data.
What data points are redacted?
The engine strips standard email addresses, 16-digit credit cards, US SSNs, Brazilian CPFs, and generic phone number formats.
Is the original text preserved?
The tool returns a completely sanitized clone of the document string, leaving the raw client source completely untouched locally.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
