Connery 工具包和工具

使用 Connery 工具包和工具，您可以将 Connery Actions 集成到您的 LangChain 代理中。

什么是 Connery？​

Connery 是一个用于 AI 的开源插件基础设施。

借助 Connery，您可以轻松创建一个包含一组动作的自定义插件，并将其无缝集成到您的 LangChain 代理中。Connery 将负责处理关键方面，例如运行时、授权、秘密管理、访问管理、审计日志以及其他重要功能。

此外，由我们社区支持的 Connery 提供了一系列多样化的即用型开源插件，以增加便利性。

设置​

安装​

您需要安装 `langchain_community` 包才能使用 Connery 工具。

%pip install -qU langchain-community

凭证​

要在您的 LangChain 代理中使用 Connery Actions，您需要进行一些准备工作

  1. 使用 快速入门 指南设置 Connery 运行器。
  2. 安装包含您希望在代理中使用的所有动作的插件。
  3. 设置环境变量 `CONNERY_RUNNER_URL` 和 `CONNERY_RUNNER_API_KEY`，以便工具包可以与 Connery 运行器通信。
import getpass
import os

for key in ["CONNERY_RUNNER_URL", "CONNERY_RUNNER_API_KEY"]:
    if key not in os.environ:
        os.environ[key] = getpass.getpass(f"Please enter the value for {key}: ")

工具包​

在下面的示例中，我们创建一个代理，它使用两个 Connery Actions 来总结一个公共网页并通过电子邮件发送总结

  1. 来自 总结 插件的总结公共网页动作。
  2. 来自 Gmail 插件的发送电子邮件动作。

您可以在此处查看此示例的 LangSmith 跟踪 这里。

注意：Connery Action 是一种结构化工具，因此您只能在支持结构化工具的代理中使用它。

工具​

import os

from langchain.agents import AgentType, initialize_agent
from langchain_community.tools.connery import ConneryService
from langchain_openai import ChatOpenAI

# Specify your Connery Runner credentials.
os.environ["CONNERY_RUNNER_URL"] = ""
os.environ["CONNERY_RUNNER_API_KEY"] = ""

# Specify OpenAI API key.
os.environ["OPENAI_API_KEY"] = ""

# Specify your email address to receive the emails from examples below.
recepient_email = "test@example.com"

# Get the SendEmail action from the Connery Runner by ID.
connery_service = ConneryService()
send_email_action = connery_service.get_action("CABC80BB79C15067CA983495324AE709")

手动运行该动作。

manual_run_result = send_email_action.run(
    {
        "recipient": recepient_email,
        "subject": "Test email",
        "body": "This is a test email sent from Connery.",
    }
)
print(manual_run_result)

使用 OpenAI Functions 代理运行该动作。

您可以在此处查看此示例的 LangSmith 跟踪 这里。

llm = ChatOpenAI(temperature=0)
agent = initialize_agent(
    [send_email_action], llm, AgentType.OPENAI_FUNCTIONS, verbose=True
)
agent_run_result = agent.run(
    f"Send an email to the {recepient_email} and say that I will be late for the meeting."
)
print(agent_run_result)

Invoking: `CABC80BB79C15067CA983495324AE709` with `{'recipient': 'test@example.com', 'subject': 'Late for Meeting', 'body': 'Dear Team,\n\nI wanted to inform you that I will be late for the meeting today. I apologize for any inconvenience caused. Please proceed with the meeting without me and I will join as soon as I can.\n\nBest regards,\n[Your Name]'}`


{'messageId': '<d34a694d-50e0-3988-25da-e86b4c51d7a7@gmail.com>'}I have sent an email to test@example.com informing them that you will be late for the meeting.
