AgenticMaid项目
概述
AgentMaid是一个Python库,旨在与一个或多个多功能协议(MCP)服务器交互。它允许动态获取和利用这些服务器提供的工具(功能)。客户端还可以管理各种AI/LLM服务的配置,安排自动化任务,处理聊天服务交互,使其成为构建AI驱动应用程序的通用组件。
它利用 langchain-mcp-adapters 用于与MCP服务器通信 langgraph 用于创建可以使用提取的MCP工具的反应剂。
特性
- 多服务器MCP交互: 连接到多个MCP服务器并利用其中的工具。
- 动态刀具抓取: 在运行时从MCP服务器检索可用工具。
- 灵活配置: 支持通过Python字典、JSON文件和
.env敏感数据的文件。 - 人工智能服务管理: 配置和利用各种AI/LLM服务(例如OpenAI、Anthropic、Azure OpenAI、本地模型)。
- 计划任务: 允许根据类似cron的计划定义和运行任务。
- 聊天服务集成: 提供一个框架,用于处理与已定义聊天服务的交互。
- 代理创建: 用途
langgraph创建可以利用MCP工具和配置LLM的ReAct代理。 - 环境变量支持: 从
.env文件。
安装
-
先决条件:
- Python 3.8+
-
克隆存储库(如果适用)或添加
AgenticMaid到你的项目。 -
安装依赖关系: 客户端依赖于多个库。确保你有一个
requirements.txt在项目中创建文件或直接安装它们。关键依赖关系包括:pip install python-dotenv langchain-mcp-adapters langgraph schedule langchain-core langchain-openai langchain-anthropic fastapi pydantic "uvicorn[standard]"上面的命令包括核心依赖项以及FastAPI服务和CLI工具所需的依赖项。文件
AgenticMaid/requirements.txt列出了主要用于API和CLI功能的依赖项。
配置
这 AgenticMaid 可以通过多种方式进行配置:
- Python词典: 将Python字典直接传递给
AgenticMaid建设者。 - JSON文件: 为构造函数提供JSON配置文件的路径。
.env文件: 对于默认值和敏感信息(如API密钥),创建.env文件在AgenticMaid/目录(即,旁边client.py).价值观来自.env文件可以被主JSON/字典配置覆盖。
配置结构
主要配置(Python字典或JSON)通常包括以下部分:
model(可选):AI模型的全局默认设置。ai_services:各种人工智能/法学硕士提供者和模型的定义。mcp_servers:客户端将连接到的MCP服务器的配置。scheduled_tasks:按计划运行的一系列任务。chat_services:客户端可以与之交互的聊天服务的定义。agents(可选):预定义的代理配置。default_llm_service_name(可选):如果未在其他地方指定,则使用全局默认LLM服务。
请参阅 AgenticMaid/config.example.json 文件中提供了一个详细的示例,并附有解释每个字段的注释。
1.使用 .env 文件
创建一个名为的文件 .env 在 AgenticMaid 目录(例如。, AgenticMaid/.env).此文件用于API密钥和其他默认设置。这里的值作为默认值,可以被主配置文件或字典覆盖。
示例 AgenticMaid/.env:
# AgenticMaid/.env example
# Default API key if not specified per service in main config
# DEFAULT_API_KEY=your_default_api_key_here
# Default model name if not specified per service in main config
# DEFAULT_MODEL_NAME=gpt-3.5-turbo-default-from-env
# Provider-specific defaults
OPENAI_API_KEY=your_openai_api_key_from_env
OPENAI_DEFAULT_MODEL=gpt-3.5-turbo-openai-from-env
ANTHROPIC_API_KEY=your_anthropic_api_key_from_env
ANTHROPIC_DEFAULT_MODEL=claude-2-from-env
# For Azure OpenAI
# AZURE_OPENAI_API_KEY=your_azure_openai_key
# AZURE_OPENAI_ENDPOINT=your_azure_endpoint
# AZURE_OPENAI_DEPLOYMENT_NAME=your_deployment_name
# For local OpenAI-compatible servers (e.g., LM Studio)
# LOCAL_OPENAI_BASE_URL=http://localhost:1234/v1
2.主配置(JSON或Python Dict)
此配置定义了MCP服务器、AI服务、任务和聊天界面的具体细节。
一 ai_services
定义您打算使用的每个AI服务。密钥是服务的自定义名称。
参见 AgenticMaid/config.example.json 对于以下领域 provider, model, api_key, base_url等等。这 api_key 可以从 .env 如果此处未提供文件。
示例片段(来自 config.example.json):
{
"ai_services": {
"openai_gemini_pro": {
"provider": "Google",
"model": "gemini-2.5-pro",
"api_key": "your_google_api_key_here_or_leave_blank_to_use_env"
},
"anthropic_claude_opus": {
"provider": "Anthropic",
"model": "claude-4-opus"
}
}
}
b mcp_servers
定义客户端应连接到的MCP服务器 MultiServerAgenticMaid (或相关类)将使用这些配置。
参见 AgenticMaid/config.example.json 对于以下领域 adapter_type, base_url (适用于FastAPI), command_template (对于CLI), name,以及 description.
示例片段(来自 config.example.json):
{
"mcp_servers": {
"server_1_local_fastapi": {
"adapter_type": "fastapi",
"base_url": "http://localhost:8001/mcp/v1",
"name": "Local FastAPI MCP Server"
}
}
}
c scheduled_tasks
定义应按计划运行的任务。每个任务对象包括:
name:任务的描述性名称。cron_expression:一个类似cron的表达式(目前支持简单的形式,如“day at HH:MM”或“0****”表示小时,通过schedule库的解释,这可能需要在中进行自定义解析_schedule_tasks对于完整的cron)。prompt:代理人的指示/提示。agent_id(可选):在agents部分。model_config_name:AI服务的名称(来自ai_services)用于此任务的代理。enabled:布尔值,true为了实现该任务,false禁用。
示例片段(来自 config.example.json):
{
"scheduled_tasks": [
{
"name": "Hourly Summary Bot",
"cron_expression": "0 * * * *", // Placeholder, actual parsing depends on _schedule_tasks
"prompt": "Generate a brief summary of activities from the last hour.",
"model_config_name": "openai_gemini_pro",
"enabled": true
}
]
}
}
这 cron_expression 解释由 schedule 图书馆。对于更复杂的cron字符串 _schedule_tasks 在...之内 AgenticMaid/client.py 可能需要调整。
d chat_services
定义不同聊天界面的配置。每个聊天服务对象包括:
service_id:聊天服务的唯一标识符。llm_service_name:AI服务的名称(来自ai_services)为这个聊天提供动力。streaming_api_endpoint(概念性):表示流式响应可能提供的路径。non_streaming_api_endpoint(概念性):非流式(完整)响应的路径。
示例片段(来自 config.example.json):
{
"chat_services": [
{
"service_id": "general_support_chat",
"service_id": "general_support_chat",
"llm_service_name": "openai_gemini_pro",
"streaming_api_endpoint": "/chat/v1/streams/general_support_chat",
"non_streaming_api_endpoint": "/chat/v1/completions/general_support_chat"
}
]
}
双提示系统
这 chat_services 配置现在支持双提示系统,以提供对代理行为的更多上下文和控制。这是通过两个可选字段实现的: system_prompt 和 role_prompt.
-
system_prompt:此提示符作为第一条消息注入system角色。它用于为AI模型提供应用于整个对话的高级指令、上下文或约束。例如,您可以定义代理的角色、核心功能和操作边界。 -
role_prompt:此提示作为user在系统提示(如果提供)之后和实际用户消息之前立即发送消息。它用于指导人工智能在接下来的对话中应该如何表现,或者应该扮演什么具体角色。这对于设定特定基调或引导代理专注于当前任务非常有用。
当处理聊天请求时,发送到AI模型的最终消息列表将按以下顺序排列:
- 系统提示(如果提供)
- 角色提示(如果提供)
- 用户消息
带有提示的示例 config.json:
{
"chat_services": [
{
"service_id": "general_support_chat_gemini",
"llm_service_name": "google_gemini_default",
"system_prompt": "You are a helpful and friendly customer support assistant for the AgenticMaid project. Your goal is to provide clear, accurate, and concise answers.",
"role_prompt": "Please answer the user's question based on the project's documentation and capabilities. Be polite and professional.",
"streaming_api_endpoint": "/chat/v1/streams/general_support_chat_gemini",
"non_streaming_api_endpoint": "/chat/v1/completions/general_support_chat_gemini"
}
]
}
用法
1.初始化
首先,导入并初始化 AgenticMaid你需要打个电话 await client.async_initialize() 在创建实例以完成异步设置(如获取MCP工具)之后。
import asyncio
from pkg_AgenticMaid.client import ClientAgenticMaid # Placeholder: Actual class name from client.py
async def main():
# Option 1: Load config from JSON file
# client = ClientAgenticMaid(config_path_or_dict='AgenticMaid/config.example.json')
# Option 2: Load config from a Python dictionary (Direct Python Invocation)
# This method is ideal for embedding AgenticMaid within other Python applications,
# allowing for dynamic configuration without relying on external JSON files.
# The .env file for API keys and defaults is still loaded if present.
config_dict = {
"ai_services": {
"my_gemini_service": { # Custom name for your service
"provider": "Google",
"model": "gemini-2.5-pro"
# API key can be provided here directly: "api_key": "AIza...",
# or if omitted, it will attempt to load from .env (e.g., GOOGLE_API_KEY)
}
},
"mcp_servers": {
"example_mcp_server": { # Custom name for your MCP server connection
"adapter_type": "fastapi", # Or other supported adapter types
"base_url": "http://localhost:8001/mcp/v1", # URL of the target MCP server
"name": "My Example MCP Server"
}
},
"default_llm_service_name": "my_gemini_service", # Default LLM for agents if not specified
# Other sections like "scheduled_tasks", "chat_services", "agents" can be added as needed.
# For a comprehensive, runnable example of direct dictionary invocation,
# please refer to the script:
# [`AgenticMaid/examples/direct_invocation_example.py`](./examples/direct_invocation_example.py)
}
client = ClientAgenticMaid(config_path_or_dict=config_dict)
# Perform asynchronous initialization
await client.async_initialize()
if client.config and client.mcp_client:
print("ClientAgenticMaid initialized successfully.")
print(f"Fetched {len(client.mcp_tools)} MCP tools: {[tool.name for tool in client.mcp_tools]}")
else:
print("ClientAgenticMaid initialization failed or no MCP tools found.")
print("AgenticMaidClient initialization failed or no MCP tools found.")
return
# ... use the client ...
if __name__ == "__main__":
asyncio.run(main())
1.1.直接字典调用的详细示例
用于演示如何实例化和使用可运行脚本 ClientAgenticMaid 使用直接字典配置,包括聊天等基本操作,请参阅示例文件:
此示例展示了如何设置配置字典并执行常见的客户端操作。
2.运行MCP交互(代理调用)
使用 run_mcp_interaction 与代理交互的方法。将使用指定的LLM服务和所有提取的MCP工具创建(或检索(如果已存在)代理。
```python
# Assuming 'client' is an initialized ClientAgenticMaid instance from the example above
# Example: Run an interaction
messages_for_agent = [{"role": "user", "content": "What is the weather in London using available tools?"}]
llm_service_to_use = "my_gemini_service" # Must be a key from your ai_services config
agent_identifier = "weather_agent_01" # A custom key for this agent instance
response = await client.run_mcp_interaction(
messages=messages_for_agent,
llm_service_name=llm_service_to_use,
agent_key=agent_identifier
)
if response and "error" not in response:
print(f"Agent Response: {response}")
else:
print(f"Agent Interaction Error: {response.get('error') if response else 'Unknown error'}")
3.运行计划任务
要运行计划任务,请首先确保在配置中定义了它们。然后,启动调度程序。调度程序在后台线程中运行。
# Assuming 'client' is an initialized ClientAgenticMaid instance
# To start the scheduler (it runs in a background thread):
if client.scheduler.jobs: # Check if there are any jobs scheduled
print("Starting scheduler...")
client.start_scheduler()
# The scheduler will now run tasks in the background.
# Keep the main thread alive if you want tasks to continue running.
# For example, in a long-running application:
# try:
# while True:
# await asyncio.sleep(1)
# except KeyboardInterrupt:
# print("Application shutting down.")
# client.stop_scheduler() # Conceptual stop
else:
print("No tasks scheduled.")
注: 这 start_scheduler 该方法在守护进程线程中运行一个无限循环。确保您的主应用程序适当地管理其生命周期。这 stop_scheduler 方法当前是占位符;更稳健的停止机制(例如,使用 threading.Event)在复杂的应用程序中,可能需要优雅地关闭。
4.与聊天服务互动
要处理已定义聊天服务的消息,请使用 handle_chat_message 方法。
# Assuming 'client' is an initialized ClientAgenticMaid instance
# Example: Interact with a chat service
chat_service_id_to_use = "general_support_chat" # Must be a service_id from your chat_services config
chat_messages = [{"role": "user", "content": "Hello, I need help with my account."}]
chat_response = await client.handle_chat_message(
service_id=chat_service_id_to_use,
messages=chat_messages,
stream=False # Set to True for streaming (currently placeholder)
)
if chat_response and "error" not in chat_response:
print(f"Chat Service Response: {chat_response}")
else:
print(f"Chat Service Error: {chat_response.get('error') if chat_response else 'Unknown error'}")
7.多代理调度
这 AgenticMaid 支持多代理调度功能,允许一个代理调用另一个代理。这使得能够创建复杂的分层代理结构,其中主代理可以将特定任务委托给专门的代理。
a.配置
要启用此功能,您必须添加 multi_agent_dispatch 部分到您的 config.json 文件。
配置字段:
enabled(boolean):设置为true以启用该功能。default_mode(string):确定默认调用模式。synchronous或sync:调用代理等待目标代理完成其任务并返回结果。concurrent:调用代理调用目标代理,并立即继续自己的执行,而无需等待结果。
allowed_invocations(object):定义哪些代理可以呼叫其他代理的字典。- 钥匙是
agent_id的 召唤 代理人(来自agents配置的一部分)。 - 这些值是一个字符串数组,其中每个字符串都是
agent_ida 目标 可以调用的代理。 - 通配符
"*"可以在数组中使用,以允许代理调用 任何 其他配置的代理。
- 钥匙是
示例 config.json 片段:
{
"multi_agent_dispatch": {
"enabled": true,
"default_mode": "concurrent",
"allowed_invocations": {
"orchestrator_agent": [
"*"
],
"summary_agent_config_ref": [
"report_agent_v2"
],
"report_agent_v2": []
}
},
"agents": {
"orchestrator_agent": {
"model_config_name": "google_gemini_default"
},
"summary_agent_config_ref": {
"model_config_name": "google_gemini_default"
},
"report_agent_v2": {
"model_config_name": "anthropic_claude4_opus"
}
}
}
在这个例子中:
orchestrator_agent可以呼叫任何其他代理。summary_agent_config_ref只能呼叫report_agent_v2.report_agent_v2无法呼叫任何其他代理。
b.提示中的用法
启用该功能后 dispatch 该工具会自动提供给被允许呼叫其他人的代理。要使用它,请在提示中指示代理调用 dispatch 工具具有所需的参数。
调度工具参数:
agent_id(string):要调用的目标代理的ID。prompt(string):传递给目标代理的提示或指令。mode(字符串,可选):调用模式(sync或concurrent).如果省略default_mode从配置中使用。
示例提示:
"Please use the dispatch tool to ask the 'report_agent_v2' to generate a detailed analysis of the latest user feedback. Run this in sync mode."
然后,代理将解析此指令并执行以下工具调用: dispatch(agent_id='report_agent_v2', prompt='Generate a detailed analysis of the latest user feedback.', mode='sync').
