Privacy Policy

Effective date: March 11, 2026

In short: WebMCP collects no data. All communication happens locally on your machine. Nothing is sent to any remote server.

What is WebMCP?

WebMCP is a Chrome extension that enables AI agents to interact with your browser using the Model Context Protocol (MCP). It acts as a bridge between AI tools running on your computer and your browser tabs.

Data Collection

WebMCP does not collect, store, transmit, or share any user data.

No personal information is collected
No browsing history is recorded or transmitted
No cookies or session data is sent externally
No analytics, telemetry, or tracking of any kind
No user accounts or registration required

Local Communication Only

All communication between the extension and the MCP server occurs exclusively over a local WebSocket connection on your machine (default: localhost:8080). No data ever leaves your computer.

The extension connects only to localhost (your own machine)
No external servers, APIs, or cloud services are contacted
No network requests are made to any remote endpoints

Password Protection

When the extension reads page content for AI agents, all password input fields are automatically masked as [filled]. The actual password value is never included in page data sent to the MCP server.

Permissions Used

WebMCP requests the following Chrome permissions, each used solely for browser automation:

activeTab — Capture page screenshots when requested by the AI agent
alarms — Keep the background service worker alive for the local WebSocket connection
storage — Save your settings (human-like delays, logging) locally in Chrome
tabs — Manage browser tabs (open, close, switch, list) for AI agents
cookies — Enable authenticated automation workflows using your existing sessions

Third-Party Services

WebMCP uses no third-party services. There are no analytics providers, ad networks, crash reporters, or external dependencies that receive user data.

Data Retention

Since no data is collected, there is no data retention. The only data stored locally in Chrome is your extension settings (toggle preferences), which you can clear at any time through Chrome's extension management page.

Children's Privacy

WebMCP does not collect any data from anyone, including children under 13. The extension is a developer tool intended for use with AI automation workflows.

Website Analytics

This website uses Cloudflare Web Analytics to measure page traffic. Cloudflare Web Analytics collects no personal data, uses no cookies, and does not track individual visitors. Only aggregated, anonymized page view counts and traffic source information are collected. No data is sold or shared with third parties for advertising. You do not need to consent to cookies to use this site.

Important distinction: This section refers only to the website you are reading now (webmcp.tanujmittal.com). The WebMCP Chrome extension and MCP server collect no analytics, telemetry, or usage data of any kind. All extension and server communication stays entirely on your machine.

Changes to This Policy

If this privacy policy is updated, the changes will be reflected on this page with an updated effective date. Since WebMCP collects no data, meaningful changes are unlikely.
