Agent Evidence MCP

中文

让 agent 在执行长任务时，自动留下截图、短录屏、备注和最终总结。

Agent Evidence MCP 不是普通截图软件，也不是浏览器自动化框架。它更像一个本地证据记录器：当 agent 正在操作浏览器、桌面软件、后台系统或多步骤流程时，它把关键状态保存成可复盘的任务记录。

适合什么场景

• agent 正在执行多步骤 UI、QA、运维、配置或排障任务
• 你希望关键节点自动留图，失败或异常时额外留证据
• 任务结束后需要 summary.md、timeline.jsonl 和所有关键产物路径
• 你想让同事、客户或之后的自己快速复盘 agent 做过什么

装上之后能做什么

• 创建任务会话：start_session
• 查看已有会话：list_sessions / get_session / get_latest_session
• 保存里程碑截图：capture_checkpoint
• 必要时录一小段屏幕：start_recording / stop_recording
• 给证据加备注或 OCR 文本：attach_note / ocr_artifact
• 生成可分享的打码副本：redact_artifact
• 比较最近的证据变化：compare_artifacts / compare_latest_artifacts
• 结束时生成可交付的任务记录：end_session
• 通过 MCP resources 读取最新 summary、artifact 列表和 session 索引
• 通过 MCP prompts 获取推荐的证据采集和最终复盘提示

推荐用法

这个项目最适合配合 agent 使用。通常只需要这样告诉 agent：

Use agent-evidence MCP for this task.
Start a session first.
Capture a screenshot at each major milestone and an extra one on errors.
Prefer screenshots over recording unless motion matters.
When the task is done, give me the summary and the key artifact paths.

3 步上手

1. 安装

从 GitHub 安装当前版本：

pip install git+https://github.com/xiexie-qiuligao/agent-evidence-mcp.git

如果你安装的是已发布到 Python 包索引的版本：

pip install agent-evidence-mcp

如果你是开发者，已经 clone 了这个仓库：

pip install -e .

2. 初始化配置

agent-evidence-mcp init

3. 启动 MCP 服务

agent-evidence-mcp serve

命令行快速体验

创建一个 session：

agent-evidence-mcp start-session "Admin QA Flow"

截一张关键节点图：

agent-evidence-mcp capture-checkpoint "D:\path\to\session" "form-submitted" "The form was submitted successfully."

结束并生成总结：

agent-evidence-mcp end-session "D:\path\to\session"

输出结构

artifacts/
  <session_id>/
    session.json
    timeline.jsonl
    summary.md
    details/
    screenshots/
    recordings/

最终拿到的不是一堆散乱截图，而是一套带时间线、摘要和元数据的任务证据包。

校验下载文件

release 页面会附带 SHA256SUMS.txt。如果你下载了 wheel 或源码包，可以这样校验：

certutil -hashfile dist\\agent_evidence_mcp-0.1.0a1-py3-none-any.whl SHA256
certutil -hashfile dist\\agent_evidence_mcp-0.1.0a1.tar.gz SHA256

English

Let your agent leave behind screenshots, short recordings, notes, and a final summary while it works through a long-running task.

Agent Evidence MCP is not a generic screenshot app or a browser automation framework. It is a local evidence recorder for agent work: when an agent operates a browser, desktop app, admin console, or multi-step workflow, this server saves the important states as a reviewable task record.

Good Fits

• multi-step UI, QA, ops, configuration, or troubleshooting tasks
• workflows where milestone screenshots and error evidence matter
• handoffs that need summary.md, timeline.jsonl, and artifact paths
• reviews where another person needs to understand what the agent did

What You Get

• start a task session with start_session
• inspect existing sessions with list_sessions, get_session, and get_latest_session
• capture milestone screenshots with capture_checkpoint
• record short screen segments when motion matters
• attach notes or OCR text to artifacts
• generate redacted copies for safer sharing
• compare recent artifacts for review-oriented changes
• finish with summary.md, timeline.jsonl, and organized artifacts
• read the latest summary, artifact list, and session index through MCP resources
• use MCP prompts for evidence capture and final review guidance

Best Way To Use It

This project is designed to work with an agent. In most cases you can simply tell the agent:

Use agent-evidence MCP for this task.
Start a session first.
Capture a screenshot at each major milestone and an extra one on errors.
Prefer screenshots over recording unless motion matters.
When the task is done, give me the summary and the key artifact paths.

Quick Start In 3 Steps

1. Install

Install the current GitHub version:

pip install git+https://github.com/xiexie-qiuligao/agent-evidence-mcp.git

If you are installing a published Python package:

pip install agent-evidence-mcp

If you are developing from a local clone:

pip install -e .

2. Initialize config

agent-evidence-mcp init

3. Start the MCP server

agent-evidence-mcp serve

Try It From The CLI

Create a session:

agent-evidence-mcp start-session "Admin QA Flow"

Capture a milestone:

agent-evidence-mcp capture-checkpoint "D:\path\to\session" "form-submitted" "The form was submitted successfully."

End the session:

agent-evidence-mcp end-session "D:\path\to\session"

What The Output Looks Like

artifacts/
  <session_id>/
    session.json
    timeline.jsonl
    summary.md
    details/
    screenshots/
    recordings/

The result is not a pile of loose screenshots. It is a reviewable task evidence package with a timeline, summary, and artifact metadata.
