AgentReady WebMCP Tester privacy policy
Last updated: October 27, 2026
AgentReady WebMCP Tester is a Chrome extension that lets you chat with Claude about the page you have open.
What it sends
The extension sends data only to Anthropic's API, with your own API key. It sends nothing to AgentReady. While the panel is open, it sends your messages, the page title and address, the site's WebMCP tools, the page text when Claude reads it, and what each tool Claude uses sends and returns. Anthropic's privacy policy covers this data.
What it keeps
Your API key, encrypted with your passcode, and your settings stay in Chrome's extension storage. The extension does not save your passcode. The chat stays only until you close the panel.
What it does not do
No analytics, no tracking, and no servers of its own. It does not collect your browsing history, and it does not sell or share data. It uses data only for the chat.
What websites see
When Claude uses a site's tool, the site gets the inputs, as if you used that feature yourself. The extension asks you first before a tool that can change something runs.
How to delete your data
In Settings, click Remove key, or remove the extension.
