+
+Please upgrade to the latest release before reporting an issue against an older build.
+
+## Reporting a Vulnerability
+
+Please do not report security vulnerabilities through public GitHub issues, discussions, or pull requests.
+
+Use GitHub's private vulnerability reporting flow:
+
+- Open https://github.com/alibaba/page-agent/security/policy
+- Click `Report a vulnerability`
+
+If private reporting is unavailable, open a minimal public issue only to request a private contact channel. Do not include exploit details.
+
+## What to Include
+
+- Affected package or feature
+- Exact version, commit, or build
+- Browser, OS, and runtime environment
+- Reproduction steps or a proof of concept
+- Expected impact
+
+## Scope
+
+We prioritize reports that show a real security boundary failure, such as:
+
+- Unauthorized access to data, tokens, or extension capabilities
+- Bypassing explicit safety constraints
+- Sensitive data exposure caused by default behavior
+
+The following usually do not qualify by themselves:
+
+- Unsafe custom integrations that ignore documented safeguards
+- Intentionally embedding secrets into client-side builds
+- Reports against unsupported older versions
+
+## Disclosure
+
+Please avoid public disclosure until maintainers have had a reasonable chance to investigate and ship a fix.

+- Added 400ms wait between agent steps for page reactions
+- Increased click wait time (100ms → 200ms) for more reliable interactions

+**Last updated:** March 2026

-"We" in this document refers to the maintainers of the open-source Page Agent project (https://github.com/alibaba/page-agent). This document covers the Page Agent software itself and the testing services we provide — **not** any third-party product or service built with it.
+"We" in this document refers to the maintainers of the open-source Page Agent project (https://github.com/alibaba/page-agent).

This document covers the software itself and the testing API we provide — **not** any third-party product or service built with it.

 ## 1. Open Source Software Privacy

-Page Agent (PageAgent.js and Page Agent Extension) is a **client-side only** tool with a "Bring Your Own Key" (BYOK) architecture. The software itself does **not** include any backend service. The software does **not** collect or transmit any user data on its own, and the maintainers do **not** have access to your browsing activity, page content, or task instructions through the software.

The software does **not** collect or transmit any user data on its own, and we do **not** have access to your browsing activity, page content, or task instructions through the software.

 All data transmission occurs **only** between your browser and the LLM provider you configure. You are in full control of which provider receives your data.

- You choose which LLM provider to use
- You may configure your own API endpoint at any time
- The project is open source and can be audited: https://github.com/alibaba/page-agent

 ## 2. Testing API and Demo Disclaimer & Terms of Use

-To facilitate easy testing and technical evaluation, we provide a free testing LLM API. This API is used in the project homepage's live demo, the pre-built demo CDN bundles, and the browser extension's default configuration. Users may also use it independently for their own technical evaluation of page-agent.

Any other use — including integration into other products or services, unlawful activities, violation of the underlying LLM provider's usage policies, or automated scraping at scale — is strictly prohibited.

-**Zero Data Retention**: We do not store, log, or use your prompts or webpage data (DOM) for model training. All data is processed in-transit and immediately discarded.

This project is not affiliated with, nor endorsed by, Alibaba Cloud.
+- **Data Processing**: We do not store or log your prompts, webpage data (HTML), or any submitted content, nor do we use such data for model training. All data is processed in-transit and immediately discarded. We perform in-memory request validation to prevent abuse of the testing API, and temporarily process IP addresses for rate-limiting purposes. No data from these processes is retained. Data is processed through Alibaba Cloud infrastructure, which is subject to its own privacy policy.

-**No Guaranteed Availability**: This testing API may be rate-limited, degraded, or discontinued at any time without prior notice.

+# @page-agent/mcp
+
+MCP server that lets AI agent clients (Claude Desktop, Copilot, etc.) control your browser through the [Page Agent](https://github.com/alibaba/page-agent) extension.
+
+## Prerequisites
+
+- Node.js >= 20
+- [Page Agent Extension](https://chromewebstore.google.com/detail/page-agent-ext/akldabonmimlicnjlflnapfeklbfemhj) installed in Chrome
+- An LLM API key (OpenAI-compatible)
+
+## Installation
+
+### Claude Desktop
+
+Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:
+
+```json
+{
+    "mcpServers": {
+        "page-agent": {
+            "command": "npx",
+            "args": ["-y", "@page-agent/mcp"],
+            "env": {
+                "LLM_BASE_URL": "https://dashscope.aliyuncs.com/compatible-mode/v1",

+            }
+        }
+    }
+}
+```
+
+### Cursor / Copilot
+
+Same format — add the config to the MCP settings of your client.
+
+## MCP Tools

+| -------------- | ------------------ | ---------------------------------------------------- |
+| `execute_task` | `{ task: string }` | Execute a browser task in natural language. Blocking. |
+| `get_status`   | —                  | Returns `{ connected, busy }`                        |
+| `stop_task`    | —                  | Stop the currently running task.                     |

+## Environment Variables
+
+| Variable         | Default | Description           |
+| ---------------- | ------- | --------------------- |

+```
+
+1. Agent client starts the MCP server via stdio (`npx @page-agent/mcp`).
+2. Server starts HTTP + WS on `localhost:PORT`, opens the launcher page in browser.
+3. Launcher page triggers the extension to open a **hub tab** (`hub.html?ws=PORT`).
+4. Hub connects to the WS server. MCP tools now proxy tasks to the hub.
