AutoDoubao

让 Codex、Hermes Agent 和 LobsterAI 自动调用已登录的豆包网页生图，并把豆包返回的原图下载到本地。

AutoDoubao 是一个 Windows 本地 MCP 桥接服务：Agent 负责提示词和图片验收，豆包网页负责实际生图，Chrome 扩展负责可靠提交和捕获原图，MCP 服务负责任务队列、下载和文件交付。

它不调用火山方舟付费生图 API，不读取账号密码，不绕过豆包登录、验证码、安全验证或免费额度限制。

项目特点

• 一套 MCP 服务同时供 Codex、Hermes Agent、LobsterAI 使用。

• 支持 Streamable HTTP；旧版 Hermes 也支持 stdio 兼容代理。

• 复用用户已经登录的豆包网页和网页免费额度，不需要购买图像 API。

• 自动填写并提交提示词，检测“文字写入但没有发送”的情况并重试。

• 监听豆包生成响应中的 image_ori_raw / image_raw，下载真实原图。

• 不从页面 <img> 的 src 或 srcset 猜原图，避免拿到 384×216 缩略图。

• SQLite 持久化任务状态，三个客户端共用单任务浏览器锁。

• 提供可迁移的 Windows ZIP 发行包，不携带 Token、Cookie、数据库或生成图片。

豆包页面上的 <img width="2848" height="1600"> 可能仍然指向 384×216 的展示缩略图。AutoDoubao 读取的是生成接口返回的原图字段，而不是页面展示地址，这是项目稳定工作的关键。

What is included

• One shared MCP service; HTTP for Codex/LobsterAI and an stdio compatibility proxy for older Hermes installations.

• Persistent SQLite jobs and a single browser-work lock.

• A generated token for the extension-to-service WebSocket.

• A Chrome Manifest V3 extension that temporarily attaches the debugger Network domain to the selected Doubao tab while a job is active. It extracts the original image_ori_raw / image_raw URL from the generation response.

• Safe output subdirectories below one configured root.

• Terminal handling for login, captcha, account verification, quota, and rate limits.

• Client configuration examples and Windows setup/start scripts.

Initial setup on Windows

1. Install Python 3.11+ and uv if they are not already available.

2. Run:

   powershell -ExecutionPolicy Bypass -File .\scripts\setup.ps1

3. Create a dedicated Chrome profile for AutoDoubao.

4. In that profile, open chrome://extensions, enable Developer mode, choose Load unpacked, and select this repository's extension directory.

5. The options page opens. Paste the token printed by the setup script and save.

6. Open https://www.doubao.com/chat/ and sign in manually.

7. Start the service:

   powershell -ExecutionPolicy Bypass -File .\scripts\start.ps1

   Or keep it running in a hidden background process:

   powershell -ExecutionPolicy Bypass -File .\scripts\start-background.ps1
   # Later: powershell -ExecutionPolicy Bypass -File .\scripts\stop-background.ps1

8. Configure clients using docs/CLIENTS.md.

MCP tools

• doubao_status: service, extension, page, queue, and output status.

• doubao_generate: queue one prompt and return a job ID.

• doubao_job_status: poll status and retrieve downloaded paths.

• doubao_cancel: cancel a job owned by the calling agent.

• doubao_list_jobs: list recent jobs without returning prompt text.

• doubao_usage: local job/image counts; it never guesses remaining free quota.

• doubao_setup_guide: setup instructions available to every MCP client.

Example agent sequence:

doubao_status()
doubao_generate(prompt="...", ratio="1:1", candidate_count=2,
                output_subdir="my-game/icons", agent_id="codex")
doubao_job_status(job_id="job_...")

Configuration

Copy config.example.yaml to config.yaml. Important settings:

• output_root: every generated image is copied below this directory.

• max_candidates_per_job: maximum requested results per job.

• max_jobs_per_hour: local safety limit shared by all agents.

• job_timeout_seconds: upper bound for one browser job.

The generated extension token is stored in data/extension-token.txt. Do not commit config.yaml, data/, downloaded output, or the token.

Browser integration

Prompt submission is isolated in extension/content.js. Image acquisition does not scrape the rendered <img> element because Doubao can display a small preview behind large DOM width/height attributes. extension/background.js listens to the generation response and downloads the original URL returned by Doubao. Chrome may show a debugging notification while a job is running; the extension detaches when the job completes, fails, times out, or is cancelled.

See docs/SECURITY.md before enabling the extension.
