 # Contributing to PageAgent
 
-Thank you for your interest in contributing to PageAgent! We welcome contributions from everyone.
+♥️ We welcome contributions from everyone.
 
-## 🚀 Quick Start
+For local development workflows, setup, local LLM config, extension development, testing on other websites, and more details, see [docs/developer-guide.md](docs/developer-guide.md).
-
-### Development Setup
-
-1. **Prerequisites**
-    - `node.js >= 20` with `npm >= 10`
-    - An editor that supports `ts/eslint/prettier`
-    - Make sure `eslint`, `prettier` and `commitlint` work well
-
-2. **Setup**
-
-    ```bash
-    npm ci
-    npm start          # Start demo and documentation site
-    npm run build      # Build libs and website
-    ```
-
-### Project Structure
-
-This is a **monorepo** with npm workspaces containing **4 main packages**:
-
-- **Page Agent** (`packages/page-agent/`) - Main entry with built-in UI Panel, published as `page-agent` on npm
-- **Core** (`packages/core/`) - Core agent logic without UI (npm: `@page-agent/core`)
-- **Extension** (`packages/extension/`) - Chrome extension for multi-page tasks and browser-level automation
-- **Website** (`packages/website/`) - React documentation and landing page. Also as demo and test page for the core lib. private package `@page-agent/website`
-
-> We use a simplified monorepo solution with `native npm-workspace + ts reference + vite alias`. No fancy tooling. Hoisting is required.
-> 
-> - When developing. Use alias so that we don't have to pre-build.
-> - When bundling. Use external and disable ts `paths` alias to leave deps out.
-> - When bundling `IIFE` and `Website`. Bundle everything including local packages.

-## 📝 Code Style
-
-### General Guidelines
-
-- Use TypeScript for type safety
-- Follow existing naming conventions
-- Write meaningful commit messages
-- Keep functions small and focused
-- Add JSDoc for public APIs
 
 ### Vibe Coding with AI
 
-> [Vibe coding](https://en.wikipedia.org/wiki/Vibe_coding) = describe what you want in natural language, let AI write the code, and you review the result.
+- Vibe coding is **NOT** allowed for the core lib or the extension!!!
-
 - Vibe coding is **RECOMMENDED** when maintaining **the demo, the website, the UI and tests**.
-    - We have a [website/AGENTS.md](packages/website/AGENTS.md) for that.
+- Make sure your AI references `AGENTS.md` and `website/AGENTS.md` for better quality.
-- Vibe coding is **NOT** allowed for the core lib!!!
-- NEVER try to vibe coding the MV3 extension!!! It is HELL.
 - Review anything AI wrote before make a commit. You are the author of anything you commit. NOT AI.
 
-If your AI assistant does not support [AGENTS.md](https://agents.md/). Add an alias for it:
-
-- claude-code (`CLAUDE.md`)
-
-    ```markdown
-    @AGENTS.md
-    ```
-
-- antigravity (`.agent/rules/alias.md`)
-
-    ```markdown
-    ---
-    trigger: always_on
-    ---
-
-    @../../AGENTS.md
-    ```
-
-## 🔧 Development Workflows
-
-### Test With Your Own LLM API
-
-- Create a `.env` file in the repo root with your LLM API config
-
-    ```env
-    LLM_MODEL_NAME=gpt-5.2
-    LLM_API_KEY=your-api-key
-    LLM_BASE_URL=https://api.your-llm-provider.com/v1
-    ```
-
-- **Ollama example** (tested on 0.15 + qwen3:14b, RTX3090 24GB):
-
-    ```env
-    LLM_BASE_URL="http://localhost:11434/v1"
-    LLM_API_KEY="NA"
-    LLM_MODEL_NAME="qwen3:14b"
-    ```
-
-    > @see https://alibaba.github.io/page-agent/docs/features/models#ollama for configuration
-
-- **Restart the dev server** to load new env vars
-- If not provided, the demo will use the free testing proxy by default. By using it, you agree to its [terms](https://github.com/alibaba/page-agent/blob/main/docs/terms-and-privacy.md).
-
-### Website Development
-
-```bash
-npm start
-```
-
-### Extension Development
-
-```bash
-# make sure you ran `npm run build:libs` first
-# and every time you changed the core libs
-npm run dev -w @page-agent/ext
-npm run zip -w @page-agent/ext
-```
-
-- Update `packages/extension/docs/extension_api.md` for API integration details
-
-### Testing on Other Websites
-
-- Start and serve a local `iife` script
-
-    ```bash
-    npm run dev:demo # Serving IIFE with auto rebuild at http://localhost:5174/page-agent.demo.js
-    ```
-
-- Add a new bookmark
-
-    ```javascript
-    javascript:(function(){var s=document.createElement('script');s.src=`http://localhost:5174/page-agent.demo.js?t=${Math.random()}`;s.onload=()=>console.log(%27PageAgent ready!%27);document.head.appendChild(s);})();
-    ```
-
-- Click the bookmark on any page to load Page-Agent
-
-> Warning: AK in your local `.env` will be inlined in the iife script. Be very careful when you distribute the script.
-
-### Adding Documentation
-
-Ask an AI to help you add documentation to the `website/` package. Follow the existing style.
-
-> Our AGENTS.md file and guardrails are designed for this purpose. But please be careful and review anything AI generated.
-

 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [1.6.0] - 2026-03-21
+
+### Features
+
+- **Beta MCP support** - New `@page-agent/mcp` package lets MCP clients such as Claude Desktop and Copilot control the browser through the Page Agent extension
+- **Better iframe handling** - Same-origin iframe elements are handled more reliably during DOM extraction and actions
+- **Extension history workflows** - Users can rerun past tasks, export history sessions as JSON, and approve MCP-triggered tasks before execution
+
+### Improvements
+
+- **Unified versioning across packages** - The extension now follows the root workspace version. Changelog entries are no longer split into a separate extension version section
+- **Configurable `stepDelay`** - Agent pacing between steps is now configurable via `stepDelay`
+- **Optional API key** - `apiKey` can now be omitted for compatible deployments that do not require one
+- **Optional named tool choice** - Tool invocation can disable named tool choice for providers that behave better without it
+- **Better rich-text input support** - Improved `contenteditable` handling with better event dispatching and `execCommand` fallback for more editors
+- **More flexible DOM extraction** - `includeAttributes` now supports wildcards, `contenteditable` is included by default, and heuristically interactive elements expose more useful attributes
+- **MiniMax model support** - Added MiniMax compatibility, with the default recommendation updated to `MiniMax-M2.7`
+
+### Bug Fixes
+
+- Fixed Safari issues when `requestIdleCallback` is unavailable
+- Avoid throwing when `webgl2` initialization fails
+- Improved OpenAI-compatible request patches for GPT-5.4 chat tools and MiniMax temperature/tool-call compatibility
+- Fixed several UI polish issues in the extension and website, including cursor and layout regressions

+# Security Policy
+
+## Supported Versions
+
+We provide security fixes on a best-effort basis for:
+
+| Version                                                   | Supported |
+| --------------------------------------------------------- | --------- |

+| Latest npm release of `page-agent` and workspace packages | Yes       |
+| Older releases                                            | No        |
+
+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.

+# Developer Guide
+
+This file is for local development workflows.
+
+For contribution rules and expectations, see [../CONTRIBUTING.md](../CONTRIBUTING.md).
+
+## 🚀 Quick Start
+
+### Development Setup
+
+1. **Prerequisites**
+    - `macOS` / `Linux` / `WSL`
+    - `node.js >= 20` with `npm >= 10`
+    - An editor that supports `ts/eslint/prettier`
+    - Make sure `eslint`, `prettier` and `commitlint` work well. Un-linted code won't pass the CI.
+
+2. **Setup**
+
+    ```bash
+    npm i
+    npm start          # Start demo and documentation site
+    npm run build      # Build libs and website
+    ```
+
+## 📦 Project Structure
+
+This is a **monorepo** with npm workspaces containing **4 main packages**:
+
+- **Page Agent** (`packages/page-agent/`) - Main entry with built-in UI Panel, published as `page-agent` on npm
+- **Core** (`packages/core/`) - Core agent logic without UI (npm: `@page-agent/core`)
+- **Extension** (`packages/extension/`) - Chrome extension for multi-page tasks and browser-level automation
+- **Website** (`packages/website/`) - React documentation and landing page. Also as demo and test page for the core lib. private package `@page-agent/website`
+
+> We use a simplified monorepo solution with `native npm-workspace + ts reference + vite alias`. No fancy tooling. Hoisting is required.
+>
+> - When developing. Use alias so that we don't have to pre-build.
+> - When bundling. Use external and disable ts `paths` alias.
+> - When bundling `IIFE` and `Website`. Bundle everything together.
+
+## 🤖 AGENTS.md Alias
+
+If your AI assistant does not support [AGENTS.md](https://agents.md/). Add an alias for it:
+
+- claude-code (`CLAUDE.md`)
+
+    ```markdown
+    @AGENTS.md
+    ```
+
+- antigravity (`.agent/rules/alias.md`)
+
+    ```markdown
+    ---
+    trigger: always_on
+    ---
+
+    @../../AGENTS.md
+    ```
+
+## 🔧 Development Workflows
+
+### Test With Your Own LLM API
+
+- Create a `.env` file in the repo root with your LLM API config
+
+    ```env
+    LLM_MODEL_NAME=gpt-5.2
+    LLM_API_KEY=your-api-key
+    LLM_BASE_URL=https://api.your-llm-provider.com/v1
+    ```
+
+- **Ollama example** (tested on 0.15 + qwen3:14b, RTX3090 24GB):
+
+    ```env
+    LLM_BASE_URL="http://localhost:11434/v1"
+    LLM_API_KEY="NA"
+    LLM_MODEL_NAME="qwen3:14b"
+    ```
+
+    > @see https://alibaba.github.io/page-agent/docs/features/models#ollama for configuration
+
+- **Restart the dev server** to load new env vars
+- If not provided, the demo will use the free testing proxy by default. By using it, you agree to its [terms](./terms-and-privacy.md).
+
+### Extension Development
+
+```bash
+# make sure you ran `npm run build:libs` first and every time you changed the core libs
+npm run dev -w @page-agent/ext
+npm run zip -w @page-agent/ext
+```
+
+- Update `packages/extension/docs/extension_api.md` for API integration details
+
+### Testing on Other Websites
+
+- Start and serve a local `iife` script
+
+    ```bash
+    npm run dev:demo # Serving IIFE with auto rebuild at http://localhost:5174/page-agent.demo.js
+    ```
+
+- Add a new bookmark
+
+    ```javascript
+    javascript:(function(){var s=document.createElement('script');s.src=`http://localhost:5174/page-agent.demo.js?t=${Math.random()}`;s.onload=()=>console.log(%27PageAgent ready!%27);document.head.appendChild(s);})();
+    ```
+
+- Click the bookmark on any page to load Page-Agent
+
+> Warning: AK in your local `.env` will be inlined in the iife script. Be very careful when you distribute the script.
+
+### Adding Documentation
+
+Ask an AI to help you add documentation to the `website/` package. Follow the existing style.
+
+> Our AGENTS.md file and guardrails are designed for this purpose. But please be careful and review anything AI generated.

+# @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",
+                "LLM_API_KEY": "sk-xxx",
+                "LLM_MODEL_NAME": "qwen3.5-plus"
+            }
+        }
+    }
+}
+```
+
+### Cursor / Copilot
+
+Same format — add the config to the MCP settings of your client.
+
+## MCP Tools
+
+| Tool           | Input              | Description                                          |
+| -------------- | ------------------ | ---------------------------------------------------- |
+| `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           |
+| ---------------- | ------- | --------------------- |
+| `LLM_BASE_URL`   | —       | LLM API base URL      |
+| `LLM_API_KEY`    | —       | LLM API key           |
+| `LLM_MODEL_NAME` | —       | Model name            |
+| `PORT`           | `38401` | HTTP + WebSocket port |

+
+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.
+
+The hub tab speaks a generic WebSocket protocol (defined in `hub-ws.ts` in the extension package) and has no knowledge of MCP. See the hub's protocol docs for message format details.
+
+## Architecture
+
+Pure JS ESM, no build step. Source files are the published artifacts.
