worker-mcp

一个 stdio MCP server,让 Claude Code(或任何 MCP 客户端)把编码任务委派给一个 worker CLI 执行。调用方(Claude)只做计划、监督和验收,worker 负责所有实际的 代码修改和命令执行。

原理

server 通过子进程调用 <worker-cli> -p <prompt> --output-format stream-json(无头模式), 解析其 stream-json 输出,把 worker 的最终回复和 session_id 返回给调用方。

默认 worker 是 Kimi Code CLI(kimi),可通过环境变量 WORKER_CLI_BIN 换成任何 兼容同一 CLI 契约的执行器:支持 -p 无头执行、-S <id> / -c 会话续接, 并以 stream-json 逐行输出 role=assistant(回复)和 role=meta(session_id)事件。

注意:worker 无头模式会自动批准所有工具调用(等同于 yolo), 可以在指定 cwd 内自由读写文件、执行命令。请只把可信的项目目录传给 cwd。

工作模式:Claude 监督计划,worker 执行

server 在 MCP instructions 和工具描述中写明了分工,Claude Code 连接后会自动遵循:

  • Claude(监督/计划):拆解目标、决定步骤顺序、为每步编写自包含任务书 (背景、涉及文件、改什么、验收标准——worker 看不到 Claude 的上下文)、 验收每步结果(读文件/diff、让 worker 跑测试)、失败时用 worker_continue 打回重修。
  • worker(执行):在指定 cwd 内完成所有实际的代码修改和命令执行。

Claude 被引导不自己调用 Edit/Write 等工具改代码(软引导,非强制拦截)。

工具

工具 说明
worker_run(prompt, cwd, timeout=600) 在 cwd 开启新 worker 会话执行任务,返回结果和 session_id
worker_continue(prompt, cwd, session_id?, timeout=600) 对既有会话追加指令;不传 session_id 时续接 cwd 最近一次会话

安装

项目内已用 uv 管理独立 Python 3.12(不依赖系统 Python):

# 如需从零重建环境:
curl -LsSf https://astral.sh/uv/install.sh | env UV_INSTALL_DIR="$PWD/.tools" INSTALLER_NO_MODIFY_PATH=1 sh
UV_PYTHON_INSTALL_DIR="$PWD/.tools/python" .tools/uv venv --python 3.12 .venv
.tools/uv pip install --python .venv/bin/python "mcp>=1.0"

注册到 Claude Code

claude mcp add worker -- /Users/quinlanhoo/Code/KIMI-MCP/KIMI-MCP/.venv/bin/python /Users/quinlanhoo/Code/KIMI-MCP/KIMI-MCP/server.py

之后在 Claude Code 中即可通过 worker_run / worker_continue 工具把任务交给 worker。

配置

环境变量 默认 说明
WORKER_CLI_BIN kimi worker CLI 路径(须兼容上述 CLI 契约)
WORKER_TIMEOUT 600 默认超时秒数(工具参数可单独覆盖)
