🚀用MCP为AutoGen开挂接入各种工具和框架!Cline零代码开发MCP Server实现接入LangFlow进行文档问答!利用MCP Server突破平

🚀🚀🚀本篇笔记所对应的视频:www.bilibili.com/video/BV1gd... AutoGen v0.4引入了对Model Context Protocol (MCP) server的支持,这是一项重要的新功能,为AI代理提供了更强大和灵活的工具使用能力。

MCP Server支持

AutoGen v0.4通过autogen_ext.tools.mcp模块提供了对MCP server的支持。这允许用户将MCP兼容的工具集成到AutoGen代理中,主要通过以下两种方式:

  1. Server-Sent Events (SSE) : 通过SseMcpToolAdapter类,可以包装基于HTTP和SSE的MCP工具。
  2. 标准输入/输出 (STDIO) : 使用StdioMcpToolAdapter类,可以包装基于命令行的MCP工具。

集成方法

AutoGen提供了便捷的方法来集成MCP工具:

  1. 使用mcp_server_tools函数可以连接到MCP server并返回所有可用工具的适配器。
  2. 这些适配器可以直接分配给AutoGen代理的工具列表,使代理能够使用这些工具。

优势

支持MCP server为AutoGen带来了以下优势:

  1. 标准化接口: MCP被描述为"AI工具的USB",提供了一种标准化的方式让AI代理发现和使用不同的功能。
  2. 灵活性: 用户可以轻松地将各种MCP兼容工具集成到他们的AutoGen工作流中,包括远程服务、云端工具和Web API。
  3. 可扩展性: 通过简单的配置,可以添加新的MCP server来扩展代理的能力。
  4. 动态工具使用: AutoGen实现了基于字典的灵活方法,使得发现和使用工具变得简单。
  5. 跨语言支持: 这种集成支持不同编程语言构建的代理之间的互操作性。
  6. 模块化和可扩展: 用户可以轻松定制系统,使用可插拔的组件,包括自定义代理、工具、内存和模型。

通过支持MCP server,AutoGen大大增强了其生态系统的开放性和可扩展性,使开发者能够更容易地集成各种工具和服务,从而创建更强大、更灵活的AI代理系统。

🔥LangFlow安装以及Cline提示词

swift 复制代码
# 安装命令
python -m pip install langflow

# 运行
python -m langflow run

## 提示词
show me some examples about Self-Consistency Prompt 

## Cline提示词

请为我开发一个用于文档问答系统的MCP Tool,
要求实现用户能够输入要检索的提示词,然后进行检索,最后获取到检索到结果。
下面是文档问答系统的API交互方式:

### 请求内容如下,其中input_value的值就是用于检索的提示词:
curl -X POST \
    "<http://127.0.0.1:7860/api/v1/run/a8e187bd-44e7-4984-9218-42f63946760b?stream=false>" \
    -H 'Content-Type: application/json'\
    -d '{"input_value": "show me some examples about Self-Consistency Prompt ",
    "output_type": "chat",
    "input_type": "chat",
    "tweaks": {
  "ChatInput-Jrzyb": {},
  "ChatOutput-rzoZb": {},
  "ParseData-hzL7Q": {},
  "File-2Teuj": {},
  "Prompt-ktajI": {},
  "MistralModel-aLZcw": {}
}}'
### 响应内容如下,其中text的值就是检索到的结果:

🔥AutoGen安装以及代码

python 复制代码
export OPENAI_API_KEY=sk-proj-xxxxxxxxxx

pip install -U "autogen-agentchat" "autogen-ext[openai]" "autogen-ext[mcp]" "mcp-server-fetch" "autogen-ext[http-tool]"

### 示例1 - 使用uvx命令调用pip安装的mcp server

import asyncio

from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
from autogen_ext.tools.mcp import StdioServerParams, mcp_server_tools

async def main() -> None:
    # Get the fetch tool from mcp-server-fetch.
    fetch_mcp_server = StdioServerParams(command="uvx", args=["mcp-server-fetch"])
    tools = await mcp_server_tools(fetch_mcp_server)

    # Create an agent that can use the fetch tool.
    model_client = OpenAIChatCompletionClient(model="gpt-4o")
    agent = AssistantAgent(name="fetcher", model_client=model_client, tools=tools, reflect_on_tool_use=True)  # type: ignore

    # Let the agent fetch the content of a URL and summarize it.
    result = await agent.run(task="Summarize the content of <https://en.wikipedia.org/wiki/Seattle>")
    print(result.messages[-1].content)

asyncio.run(main())

### 示例2 - 使用node命令直接调用已安装mcp server

import asyncio

from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
from autogen_ext.tools.mcp import StdioServerParams, mcp_server_tools

async def main() -> None:
    # Get the fetch tool from mcp-server-fetch.
    fetch_mcp_server = StdioServerParams(command="node", args=["/Users/charlesqin/Documents/Cline/MCP/browser-use/build/index.js"])
    tools = await mcp_server_tools(fetch_mcp_server)

    # Create an agent that can use the fetch tool.
    model_client = OpenAIChatCompletionClient(model="gpt-4o-mini")
    agent = AssistantAgent(name="fetcher", model_client=model_client, tools=tools, reflect_on_tool_use=True)  # type: ignore

    # Let the agent fetch the content of a URL and summarize it.
    result = await agent.run(task="show me some examples about Self-Consistency Prompt ")
    print(result.messages[-1].content)

asyncio.run(main())
