01 // How It Works & Runtime Architecture

By leveraging Python SDK / OpenAI API, the application isolates runtime dependencies while maintaining low-latency execution traces across multi-step LLM operations.

03 // Prerequisites & Compatibility

✓
Runtime Environment
Python 3.10+ installed and available in system PATH
✓
Compatible Client
Claude Desktop, Cursor, Windsurf, Claude Code CLI, or OpenCode
✓
Directory Permissions
Explicit filesystem read/write access to designated directories
✓
License Compliance
Verified permissive Apache-2.0 open-source license

04 // Client Configuration (claude_desktop_config.json) 

{
  "mcpServers": {
    "easel": {
      "command": "python",
      "args": [
        "-m",
        "easel"
      ]
    }
  }
}

Paste into your client configuration file (e.g. ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%/Claude/claude_desktop_config.json on Windows).

05 // Step-by-Step Installation

Verified Process
  1. 1

    Clone ZJU-REAL/Easel from GitHub

  2. 2

    Install dependencies with pip install -r requirements.txt (or uv sync)

  3. 3

    Copy .env.example to .env and add your API keys

  4. 4

    Run the skill server and connect your AI client via stdio or HTTP

06 // Execution Boundaries & Security Safeguards

● Context Protection

Keeps heavy parsing and raw file structures external to the LLM. Only sanitized excerpts and structured returns are injected into agent memory turns.

● Directory Allowlisting

Enforce explicit directory allowlists and permission scopes in client configuration to ensure autonomous tool calls never breach system boundaries.

● Process Isolation

Executes in an isolated local child process communicating strictly over JSON-RPC via stdio with explicit process timeouts.

07 // Frequently Asked Questions

FAQ Schema Included

What is Easel and how does it empower AI agents?

Easel is an open-source automation capability designed for AI clients and autonomous agents. An open-source AI agent for social media — discover trends, create content, publish everywhere, and learn what works across Xiaohongshu, Douyin, Zhihu, Bilibili, and more.🎨一个开源的 AI 社交媒体智能体——发现热点趋势、创作内容、一键发布至各大平台，并学习分析哪些内容真正有效，覆盖小红书、抖音、知乎、哔哩哔哩等平台。.

How do I install and configure Easel?

Follow the step-by-step installation: 1) Verify your runtime (Python 3.10+), 2) Add the configuration snippet into your AI client settings (e.g. claude_desktop_config.json), 3) Restart the client to initialize tool execution.

Which AI clients and developer harnesses support Easel?

Easel is compatible with all AI tools supporting tool-calling and the Model Context Protocol (MCP), including Claude Desktop, Cursor, Claude Code CLI, Windsurf, OpenCode, and custom agent runtimes.

What security boundaries and sandboxing safeguards does Easel enforce?

Easel executes locally with strict directory allowlists and permission scopes. Heavy parsing and raw file structures stay external to the LLM context window to prevent memory saturation and unauthorized access.

Is Easel free and open source?

Yes, Easel is published under the Apache-2.0 open-source license. You can inspect the source code and contribute on GitHub at https://github.com/ZJU-REAL/Easel.
