PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "ztds": {
      "command": "npx",
      "args": [
        "-y",
        "ztds-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add ztds -- npx -y ztds-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "ztds": {

Common questions

Is Ztds safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 42 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

ztds-mcp & ztds-audit — Zero-Trust Data Sanitization (ZTDS™ RFC v1.0) MCP Server & Invariant Auditor

This repository contains the official Model Context Protocol (MCP) Server implementation (`ztds-mcp`) and Codebase Invariant Auditor (`ztds-audit`) for the Zero-Trust Data Sanitization (ZTDS™ RFC v1.0) standard. Maintained by the ZTDS AI Consortium.

  • MCP Server Source Code (in this repository): packages/ztds-mcp/index.js
  • MCP Manifest & Server Card: packages/ztds-mcp/manifest.json | server-card.json | smithery.yaml
  • MCP Server Test Suite: packages/ztds-mcp/test.js
  • CLI Invariant Auditor: bin/ztds-audit.js

ZTDS™ governs in-memory data sanitization for AI agents, IDE assistants (Claude Desktop, Claude Code, Cursor, Windsurf, Zed), retrieval-augmented generation (RAG), and Large Language Model (LLM) pipelines. It executes 100% locally in volatile device memory (RAM) with zero external network calls, zero disk writes, and zero subprocessors.


1. MCP Server Implementation (ztds-mcp)

The reference MCP server (packages/ztds-mcp/index.js) implements the Model Context Protocol (2024-11-05) over stdio JSON-RPC 2.0 transport with zero external runtime dependencies. It intercepts sensitive cleartext (PII, PHI, API secrets, IBANs, credit cards) in client RAM prior to LLM dispatch, substitutes deterministic surrogate tokens ([EMAIL_TOKEN_1], [API_SECRET_TOKEN_1]), and restores authentic values locally in LLM responses.

1.1 Installation & MCP Client Configuration
Option A: 1-Click Automated Setup
npx ztds-mcp init
Option B: Claude Desktop (claude_desktop_config.json) & Cursor IDE (.cursor/mcp.json)
{

"mcpServers": { "ztds": { "command": "npx", "args": ["-y", "ztds-mcp"] } } }

Option C: Run Directly from Repository Source
{

"mcpServers": { "ztds": { "command": "node", "args": ["/absolute/path/to/ztds.ai/packages/ztds-mcp/index.js"] } } }

Option D: Claude Code CLI
claude mcp add ztds -- npx -y ztds-mcp

1.2 MCP Tools (tools/list & tools/call)

Implemented in packages/ztds-mcp/index.js:

Tool NameInput Schema (properties)Description
ztds_sanitizetext (string, required), sessionId (string, optional)Masks sensitive PII, PHI, and credentials in client volatile RAM with deterministic surrogate tokens ([EMAIL_TOKEN_1], [API_SECRET_TOKEN_1]) before LLM ingestion and emits a cryptographic SHA-256 ZTDS-RECEIPT-* attestation.
ztds_restoretext (string, required), sessionId (string, optional)Restores original unmasked cleartext from surrogate tokens locally in volatile RAM using atomic single-pass lookup (preventing second-order token injection).
ztds_audittext (string, required)Audits text or file contents for exposed credentials and PII against ZTDS RFC v1.0, returning category breakdowns, risk level (LOW/HIGH/CRITICAL), and a SHA-256 compliance receipt.
ztds_info{} (no arguments)Returns active ZTDS RFC v1.0 protocol status, IETF Standards Track metadata, and volatile RAM session metrics.
ztds_reset_sessionsessionId (string, optional)Explicitly zeroizes and destroys the volatile in-memory surrogate mapping table (Theorem 2 RAM zeroization).
Example JSON-RPC tools/call (ztds_sanitize -> ztds_restore)

Request (`ztds_sanitize`):

{

"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "ztds_sanitize", "arguments": { "text": "Customer alice@acme.org reported failure with key sk-proj-demo-key.", "sessionId": "ide-session-01" } } }

Response:

{

"jsonrpc": "2.0", "id": 1, "result": { "content": [ { "type": "text", "text": "Customer [EMAIL_TOKEN_1] reported failure with key [API_SECRET_TOKEN_1].\n\n> [ZTDS Invariant 1 Attested] Zero external network egress.\n> Receipt: ZTDS-RECEIPT-8F4B2C19E0A3D712 | Execution: 42µs | Entities Masked: 2" } ], "isError": false } }


1.3 MCP Resources (resources/list & resources/read)

The MCP server exposes structured read-only protocol and telemetry resources via resources/list and resources/read:

Resource URIMIME TypeDescription
ztds://spec/rfc-v1application/jsonFormal ZTDS RFC v1.0 / IETF draft-sibiryakov-ztds-protocol specification metadata and the 4 core mathematical invariants.
ztds://session/telemetryapplication/jsonReal-time volatile RAM session count, capacity limits, and zero-egress attestation status (zero cleartext exposure).

1.4 MCP Prompts (prompts/list & prompts/get)
Prompt NameArgumentsDescription
ztds_guardtask (string, required)Activates the ZTDS Zero-Trust Data Sanitization guardrail for the current IDE/agent workflow, instructing the model to invoke ztds_sanitize prior to external reasoning and ztds_restore on output.

1.5 Programmatic / Node.js SDK Usage (packages/ztds-mcp/index.js)

The MCP server module exports its JSON-RPC dispatcher and in-memory sanitization primitives for direct programmatic integration and testing:

import {

handleMessage, sanitizeText, restoreText, auditText, resetSessionStore, TOOLS, PROMPTS, RESOURCES } from './packages/ztds-mcp/index.js';

// 1. Direct in-memory sanitization & restoration const scrubbed = sanitizeText('Send wire to DE89370400440532013000 for john@example.com', 'session-1'); console.log(scrubbed.sanitizedText); // "Send wire to [IBAN_TOKEN_1] for [EMAIL_TOKEN_1]"

const restored = restoreText(Confirmed transfer to ${scrubbed.sanitizedText}, 'session-1'); console.log(restored.restoredText);

// 2. Direct MCP JSON-RPC 2.0 protocol invocation const rpcResponse = await handleMessage({ jsonrpc: '2.0', id: 1, method: 'tools/list', params: {} });

// 3. Zeroize volatile session memory (Theorem 2) resetSessionStore('session-1');

Run the MCP server verification suite locally:

node packages/ztds-mcp/test.js

2. The 4 Fundamental Invariants (RFC v1.0)

Every AI pipeline protected by ztds-mcp and audited by ztds-audit is verified against the 4 core mathematical and architectural invariants:

  1. Invariant 1: Zero External Egress Prior to Sanitization: Raw sensitive cleartext (PII, PHI, API secrets, private financial numbers) must never cross the local execution boundary prior to reversible surrogate tokenization.
  2. Invariant 2: Deterministic Reversible Tokenization: Semantic, syntactic, and structural context must be preserved for LLM reasoning while de-identification lookup tables remain strictly in local host volatile memory.
  3. Invariant 3: Cryptographic & In-Memory Isolation: Operations run in volatile heap or hardware-attested enclaves (WASM, Nitro Enclaves, C-ABI) with zero unencrypted disk spill and immediate memory zeroization.
  4. Invariant 4: Continuous Subprocessor Exclusion: Local client-side execution eliminates third-party transmission, legally exempting deployments from GDPR Article 28 data processing agreements (Zero-DPA).

3. Codebase Invariant Auditor CLI (ztds-audit)

Run a zero-install security and invariant audit across your codebase or AI agent repository:

npx ztds-audit --dir ./src --strict
Command-Line Flags
FlagDescriptionDefault
-d, --dir Target directory to auditCurrent working directory
--jsonOutput structured machine-readable JSON reportfalse
