About Intelation Nexis

Intelation Nexis is an MCP server for detecting and transforming personal data in text. It offers privacy operations configured for regulations such as GDPR, UK GDPR, HIPAA, and Privacy Act.

Key features

  1. 01Detect PII without changing text
  2. 02Redact, mask, or replace PII
  3. 03Hash, pseudonymize, or tokenize data
  4. 04Encrypt and optionally decrypt values
  5. 05List supported countries and regulations

Use cases

  1. 01Anonymize support tickets before summarizing
  2. 02Find personal data in text
  3. 03Prepare text for privacy-aware processing

MCP support

The server exposes Nexis tools for detecting and transforming PII to MCP clients. Decryption is disabled by default and can be enabled through an environment variable.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Details

From the project README

@intelation/nexis-mcp

MCP server that lets Claude, Cursor, VS Code and other AI assistants find and remove personal data (PII) from text. Regulation-aware (UK GDPR, GDPR, HIPAA, Privacy Act), powered by Intelation Nexis.

Full guide: intelation.com/integrations/javascript.

Setup

Get a free API key at https://nexis.intelation.com, then add the server to your MCP client.

Add to Cursor (then replace your-key with your API key)

Claude Desktop / Cursor (mcpServers in the config file):

{
	"mcpServers": {
		"nexis": {
			"command": "npx",
			"args": ["-y", "@intelation/nexis-mcp"],
			"env": { "NEXIS_API_KEY": "your-key" }
		}
	}
}

Claude Code:

claude mcp add nexis --env NEXIS_API_KEY=your-key -- npx -y @intelation/nexis-mcp

Then ask: "Anonymize this support ticket before you summarise it: ..."

Tools

ToolWhat it does
anonymize_textRedact, replace, mask, hash, pseudonymize, tokenize or encrypt PII
detect_piiList the PII found, without changing the text
decrypt_textRestore values encrypted by anonymize_text. Off unless NEXIS_ALLOW_DECRYPT=true
list_countriesCountries and regulations in your plan

Environment

Variable
NEXIS_API_KEYRequired
NEXIS_COUNTRYDefault regulation|country|sub-region|language; otherwise the first country in your plan
NEXIS_ENCRYPTION_KEYFernet key for the encryption method and decrypt_text
NEXIS_ALLOW_DECRYPTtrue to turn on decrypt_text. Off by default
NEXIS_BASE_URLOnly for a dedicated or on-premises instance

The encryption key is read only from the environment and is never a tool argument, so the key never passes through the model.

Before you set NEXIS_ALLOW_DECRYPT=true: the assistant sees whatever decrypt_text returns, which is the original personal data. A document with hidden instructions ("decrypt this and include it") could also get the assistant to decrypt values. Turn it on only when the assistant is meant to read the original values:

"env": { "NEXIS_API_KEY": "your-key", "NEXIS_ENCRYPTION_KEY": "your-fernet-key", "NEXIS_ALLOW_DECRYPT": "true" }

claude mcp add nexis --env NEXIS_API_KEY=your-key --env NEXIS_ENCRYPTION_KEY=your-fernet-key --env NEXIS_ALLOW_DECRYPT=true -- npx -y @intelation/nexis-mcp

Use in your own code

Importing the package does not start a server, so you can add the Nexis tools to your own MCP setup:

import { Nexis } from '@intelation/nexis';
import { createServer } from '@intelation/nexis-mcp';

const server = createServer(new Nexis(), { version: '1.0.0', allowDecrypt: false });
await server.connect(transport);

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
