README

flow-codeblock-mcp

Flow Codeblock 的本地 stdio MCP Server 与 Codex Skill。MCP 只调用 Flow Codeblock Rust REST API，不在用户电脑执行用户 JavaScript；用户代码仍由服务端固定版本 Bun Supervisor 执行。

安装

需要 Bun 1.4.0 或更高版本：

bunx --bun flow-codeblock-mcp@0.2.6

必须配置：

FLOW_CODEBLOCK_BASE_URL=https://qingcode.oalite.com
FLOW_CODEBLOCK_TOKEN=flow_xxx

FLOW_CODEBLOCK_BASE_URL 是已部署的 Flow Codeblock Rust API 地址。公网服务使用 https://qingcode.oalite.com；仅当用户在本机部署 Rust 服务时才改为对应的 localhost 地址。Token 应使用客户端的环境变量或密钥配置，不要写入提示词、工具参数或公开文件。

通用 stdio MCP 配置

{
  "mcpServers": {
    "flow-codeblock": {
      "command": "bunx",
      "args": ["--bun", "flow-codeblock-mcp@0.2.6"],
      "env": {
        "FLOW_CODEBLOCK_BASE_URL": "https://qingcode.oalite.com",
        "FLOW_CODEBLOCK_TOKEN": "<YOUR_FLOW_CODEBLOCK_TOKEN>"
      }
    }
  }
}

npm 包包含 MCP 运行源码、flow-codeblock Skill、AGENT_PROMPT.md、模块/危险模式规则和接口文档 Schema。普通 MCP 客户端不会自动安装 Codex Skill，但 flow_write_code 会直接读取包内权威规则，因此不依赖 Skill 注入也能获得完整代码契约。

使用约束

  • 写代码前调用 flow_write_code；非脚本模式从 input.<字段> 读取，脚本模式从 input.query/header/body/cookies 读取。
  • 创建或更新脚本必须先调用 flow_preview_script_change，向用户展示预览并获得明确确认后才能调用 flow_apply_script_change。
  • 脚本 POST 调用方直接提交业务 JSON，不包装为 input 或 input.body。
  • MCP 不提供删除脚本工具；删除需要用户通过网页或 REST API 自行操作。
  • 执行操作正常进行认证、限流、配额扣减、安全校验、统计和审计。
