agent-workflow-mcp
基于**模型上下文协议(MCP)**构建的生产级多智能体工作流编排器。规划器/执行器/评论家智能体栈驱动类型化的工具调用循环,与 MCP 工具服务器通信,并写入持久化、可重放的任务运行轨迹。
为什么
大多数智能体框架止步于聊天循环。agent-workflow-mcp 更进一步:确定性规划、结构化工具调用、MCP 原生工具发现、带退避的重试、持久化运行状态,以及可端到端重放的轨迹日志。专为无人值守数小时运行而设计,并能在崩溃后从断点继续执行。

特性
规划器 / 执行器 / 评论家智能体:将目标分解为类型化计划、调度工具调用,并在提交前对每个步骤进行评审。
MCP 客户端 + 服务端传输,支持 stdio 和 WebSocket,完整支持 JSON-RPC 2.0 协议及能力协商。
工具调用循环,具备有限重试、指数退避、模式验证和停止条件钩子,防止循环失控。
持久化运行状态:每个步骤、工具调用和中间消息都会追加到事件日志中,支持重放或恢复。
OpenTelemetry 风格追踪,包含跨度 ID、父级链接、令牌统计和按智能体角色区分的延迟直方图。
类型化配置,基于 Pydantic v2,支持按配置文件覆盖(
default、dev、prod)。可插拔提供方:内置 Anthropic 适配器,并提供简洁的
Provider协议以支持 OpenAI、Bedrock 或本地后端。CLI,包含
serve、run、replay、trace子命令,并支持 JSON 输出以便脚本化。92% 测试覆盖率,针对重试和重放逻辑提供基于属性的测试。
