Executive Regulatory Insight & Strategic Takeaway

Cline and Roo Code connect VS Code directly to local files and system commands. Exposing workspace assets without filtering risks automated exfiltration. Enforcing local data masking at the extension layer satisfies SOC 2 requirements.

By integrating PrivacyScrubber into your agentic workflows, you can natively protect against data leaks. This is especially critical when managing RAG privacy protocols. Unlike standard cloud filters, our local CLI coding environments ensures 100% local processing, strictly adhering to SOC 2 agent audits without any network overhead.

What AI Engineers and Agent Builders Send to AI — and What They Should Be Sending Instead

Addressing Securing Cline and Roo Code is a core operational priority for engineering, product, and leadership teams. As organizations integrate LangChain, LlamaIndex, AutoGPT, CrewAI, and custom RAG infrastructure, the liability of unmanaged PII exfiltration to public LLM datasets represents a critical risk to agents standing. Our agents AI privacy guides provide the technical roadmap for maintaining the agents perimeter while adopting GenAI. The core vulnerability: autonomous agents that accumulate PII across memory, tool calls, and vector store indexes — creating persistent privacy liabilities impossible to manually audit.

Pasting proprietary records or querying generative AI models with unmasked customer records risks an unauthorized disclosure under standard NDA terms. Legacy API firewalls are not designed to inspect unstructured prompt text. For AI engineers, LLM application developers, and enterprise AI architects, preventing exfiltration requires local verification at the endpoint. Learn how to configure the local PrivacyScrubber MCP server in Cline (formerly Claude Dev) and Roo Code to sanitize customer PII, secrets, and database tables locally inside VS Code.

Deploy Zero-Trust DLP for Developer Fleets

Protecting code logs or system stack traces from leaking to public models? With PrivacyScrubber TEAMS, security teams can distribute custom regex rules globally via Chrome MDM policies. Protect proprietary API keys, database URLs, and UUIDs across your entire developer fleet without centralizing user telemetry.

Zero-Trust Configuration & Threat Model

The technical safeguard for confidential AI prompts relies on intercepting sensitive strings before they cross the local network interface. By replacing actual values with deterministic placeholders (e.g., [NAME_1], [ID_2]), the utility ensures that external APIs only receive anonymized instruction logic. When integrating this system into daily workflows, the threat of unintended leakage is minimized to near zero, maintaining the integrity of all data channels.

Verification Protocol

  • Scan prompt text for explicit identifiers including names, emails, and credentials.
  • Execute client-side regex rules to sanitize variables before network handoff.
  • Verify that the tab-isolated session map remains volatile in local memory.
  • Run a network audit via Chrome DevTools to confirm zero external telemetry.

Autonomous AI Agent Risk in VS Code

VS Code extensions like Cline (formerly Claude Dev) and Roo Code have shifted developer AI assistance from autocomplete to autonomous agency. These extensions read local codebases, construct and execute bash commands, and connect to local services to solve bugs.

However, when an autonomous agent searches your repository for context, it frequently opens log files, credentials, and API handler code. Without endpoint filtering, all read file contents — including database connection keys, customer metrics, and PII — are passed directly to OpenAI, Anthropic, or OpenRouter.

Similar to how Cursor AI Source Code Leaks occur during context aggregation, Cline and Roo Code expose raw workspace data. Inserting a local Model Context Protocol (MCP) server filters this data in memory before transmission.

Configuring the MCP Server in Cline

Cline manages its MCP servers via a global settings file. To add PrivacyScrubber, edit your local config:

Cline Configuration Paths

  • macOS:~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json
  • Windows:%APPDATA%CodeUserglobalStoragesaoudrizwan.claude-devsettingscline_mcp_settings.json
{
  "mcpServers": {
    "privacyscrubber": {
      "command": "node",
      "args": ["/absolute/path/to/@privacyscrubber/mcp-server/index.js"]
    }
  }
}

Configuring the MCP Server in Roo Code

Roo Code matches Cline's architecture but stores settings under its own extension path:

Roo Code Configuration Paths

  • macOS:~/Library/Application Support/Code/User/globalStorage/roocode.roo-cline/settings/cline_mcp_settings.json
  • Windows:%APPDATA%CodeUserglobalStorage oocode.roo-clinesettingscline_mcp_settings.json

Centralized Security for VS Code Fleets

While individual developers can secure their own workstations, enterprise environments require uniform compliance controls. If your team is preparing for a SOC 2 audit or managing data sovereignty under GDPR regulations, relying on developers to manually maintain local exclusions is a liability.

The PrivacyScrubber TEAMS plan addresses this with Shared Regex Governance. The security lead defines proprietary credential formats, log patterns, and sensitive database field structures once, distributing them cryptographically to all local Cline and Roo Code instances. This establishes a verifiable, local-only compliance boundary that never transmits telemetry to external servers.

Zero-Trust Architecture

PrivacyScrubber operates entirely on your device. Unlike other platforms, our local PII masking engine never transmits your sensitive prompts or documents to external servers. All detection and restoration happens in your computer's local RAM.

  • No Backend Connection: Zero API calls, zero tracking, zero logs.
  • Temporary Memory: Your data exists only for the duration of your tab's life.
  • Verification Ready: Built for professionals who need to audit their security layer with air-gapped agentic memory.

Hardware-Level Verification

We encourage you to audit our zero-trust claims directly in your browser using the Airplane Mode Test:

1

Open your browser's Network Monitor before you start scrubbing.

2

Switch to Airplane Mode (physical or simulated) and protect your text.

3

Verify that no data packets ever leave your machine.

Why AI Safety and Security Governance Teams Flag Unmasked AI Prompts

The security standards are clear: GDPR data minimization principles, NIST AI RMF (Risk Management Framework), and emerging agentic AI governance guidance. Yet, daily employee workflows demand high-speed summarization. Addressing this gap requires checking the patterns in salesforce agentforce compliance to understand how unredacted logs translate into liability. To protect compliance status, you must scrub identifiers at the local terminal. Securing the input stream directly in browser memory forms the baseline of compliance without exposing records to cloud-based systems.

Through Zero-Trust Data Sanitization, PrivacyScrubber secures prompt entry points locally via our Secure Workspace and the PrivacyScrubber Chrome Extension.

How to Use AI on Real AI Agent and Workflow Data — Without Sending a Single Real Name

Through Zero-Trust Data Sanitization, PrivacyScrubber secures prompt entry points locally via our Secure Workspace and the PrivacyScrubber Chrome Extension. The system tokenizes customer and business identifiers (such as [ID_1]) before exfiltration, aligning with standard procedures for scaling agent architectures. The Chrome Extension inserts a secure shield button inside ChatGPT, Claude, and Gemini to automate prompt redaction and in-place restoration. By executing deterministic ZTDS™ detection parsing entirely in local memory, PrivacyScrubber preserves the usefulness of LangChain, LlamaIndex, AutoGPT, CrewAI, and custom RAG infrastructure for production workflows without introducing external risk.

This zero-transmission architecture is independently auditable via our Airplane Mode Standard. By disconnecting your network and running a full scrub-and-restore cycle, you verify that no outbound packets are transmitted. This aligns with air-gapped agentic memory for hardened agents security: local execution is the primary safeguard for AI data privacy.

New Capability: Local Image OCR & Zero-Trust Sync

The PrivacyScrubber Chrome Extension now supports Local Image OCR. Paste screenshots directly into the extension popup to redact sensitive PII offline using an isolated WebAssembly worker. Combined with our new Zero-Trust Session Sync, enterprise teams can seamlessly share custom detection rules without ever transmitting data to cloud servers.

Frequently Asked Questions

Common questions about deploying zero-trust AI for Agents Teams.

What is Cline and Roo Code, and why do they pose a privacy risk?
Cline (formerly Claude Dev) and Roo Code are autonomous AI agent extensions for VS Code. They can read your workspace files, run terminal commands, and inspect databases. If they access sensitive logs, customer database records, or environment files, that raw data is transmitted to cloud LLM providers. PrivacyScrubber intercepts and masks this data locally first.
How do I configure the PrivacyScrubber MCP server in Cline?
Cline stores its MCP settings in `~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json` (macOS) or `%APPDATA%/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json` (Windows). Adding the PrivacyScrubber block to this JSON file activates local sanitization.
How do I configure the PrivacyScrubber MCP server in Roo Code?
Roo Code uses a similar configuration file located in its specific extension globalStorage directory: `~/Library/Application Support/Code/User/globalStorage/roocode.roo-cline/settings/cline_mcp_settings.json`. Add the PrivacyScrubber command block there to enforce tokenization.
Does this require team seats or can it be managed centrally?
Individual developers can run it locally on the Free or PRO tier. For security teams, the TEAMS plan allows central distribution of custom masking rules via a single cryptographic link, ensuring all developers run identical sanitization profiles in VS Code.
Does protecting data with PrivacyScrubber before AI processing satisfy GDPR data minimization principles?
Yes. Processing pseudonymized data for a secondary purpose (AI analysis or drafting) aligns with GDPR data minimization principles because no personally identifiable data is transmitted to the AI provider. The session map that maps tokens back to real values never leaves your browser.
What specific PII does PrivacyScrubber detect for agents workflows?
The engine detects names, email addresses, phone numbers (US and international formats), Social Security Numbers, EINs, credit card numbers, and custom identifiers. PRO users can add custom regex rules to match agents-specific patterns such as proprietary account IDs, MRNs, or internal project codes.
Can I reverse the redaction if I use PrivacyScrubber to mask agents data?
Yes. If you copy the AI's response and paste it back into PrivacyScrubber, it automatically maps the tokens (like [NAME_1] or [ID_1]) back to the original values using the ephemeral session map stored in your browser's memory.
Can PrivacyScrubber be used 100% offline without network requests?
Yes. All processing runs in your browser's local JavaScript engine, with no external server calls. Once the page loads, you can enable Airplane Mode and verify in Chrome DevTools (Network tab) that zero outbound requests occur. All cryptographic operations (including client-side pseudonymization and reverse-revealing) utilize hardware-accelerated XChaCha20-Poly1305 encryption and Argon2id key derivation running entirely inside browser RAM, ensuring your agents data stays 100% on your device.
How can I verify that PrivacyScrubber sends zero data to servers?
Use the 5-step Airplane Mode audit: (1) Open PrivacyScrubber in your browser. (2) Disconnect your network connection (enable Airplane Mode). (3) Paste a text sample containing names, emails, and phone numbers. (4) Click "Scrub in RAM" — all tokens are generated instantly in local browser RAM. (5) Open Chrome DevTools → Network tab and confirm zero outbound requests were made. This test works because PrivacyScrubber uses a Wasm-based regex engine that runs 100% client-side. The session token map (e.g. [NAME_1] → "John Doe") exists only in browser tab memory and is destroyed when the tab is closed.
Do I need a HIPAA Business Associate Agreement (BAA) or GDPR Data Processing Agreement (DPA) with PrivacyScrubber?
No. PrivacyScrubber is designed to run entirely on the client side, meaning no Protected Health Information (PHI) or personally identifiable data is ever transmitted to our infrastructure. Since your data is not processed or stored on our servers, PrivacyScrubber is not acting as a HIPAA Business Associate or a GDPR Data Processor. Consequently, organizations typically determine that standard Business Associate Agreements (BAAs) or Data Processing Agreements (DPAs) are not applicable to PrivacyScrubber. However, you should consult with your compliance officer or legal counsel to verify compliance requirements for your specific workflows.
Can I customize detection rules for industry-specific data formats?
Yes. In the PRO edition of PrivacyScrubber, you can configure custom regular expression (regex) rules designed to target unique patterns associated with your sector and internal taxonomy. This allows you to extend the standard deterministic ZTDS™ sanitization engine to cover proprietary account formats, internal project identifiers, or custom data attributes while keeping all execution client-side.
Is pasting sensitive data into ChatGPT safe?
Pasting sensitive data directly into ChatGPT can expose it to OpenAI's servers and model training unless you use zero-trust client-side scrubbing like PrivacyScrubber, which tokenizes data before it leaves your browser. Protect your workflows for $15/mo with PRO.
How does client-side PII redaction work?
Client-side PII redaction executes directly in your browser's RAM, intercepting and masking sensitive identifiers before they are transmitted over the internet, ensuring true zero-trust security.
How does the Secure Workspace differ from the Browser Extension?
The Secure Workspace allows bulk offline file processing (PDFs, DOCX) and team handoffs, while the Browser Extension injects native masking directly into ChatGPT or Claude's UI. Both are included in our zero-trust ecosystem.
What is the PII MCP Server used for?
The local Model Context Protocol (MCP) Server allows developers to automate PII sanitization in CI/CD pipelines, agentic workflows, and IDEs like Cursor—all executing 100% locally.
