This guide provides a quick overview for getting started with Discord tooling in langchain_discord. For more details on each tool and configuration, see the docstrings in your repository or relevant doc pages.

Overview

Integration details

ClassPackageSerializableJS supportPackage latest
DiscordReadMessages, DiscordSendMessagelangchain-discord-shikensoN/ATBDPyPI - Version

​
Tool features

  • DiscordReadMessages: Reads messages from a specified channel.
  • DiscordSendMessage: Sends messages to a specified channel.

​
Setup

The integration is provided by the langchain-discord-shikenso package. Install it as follows: 
%pip install --quiet -U langchain-discord-shikenso

​
Credentials

This integration requires you to set DISCORD_BOT_TOKEN as an environment variable to authenticate with the Discord API. 
export DISCORD_BOT_TOKEN="your-bot-token"

import getpass
import os

# Example prompt to set your token if not already set:
# if not os.environ.get("DISCORD_BOT_TOKEN"):
#     os.environ["DISCORD_BOT_TOKEN"] = getpass.getpass("DISCORD Bot Token:\n")
You can optionally set up LangSmith for tracing or observability: 
# os.environ["LANGSMITH_TRACING"] = "true"
# os.environ["LANGSMITH_API_KEY"] = getpass.getpass()

​
Instantiation

Below is an example showing how to instantiate the Discord tools in langchain_discord. Adjust as needed for your specific usage. 
from langchain_discord.tools.discord_read_messages import DiscordReadMessages
from langchain_discord.tools.discord_send_messages import DiscordSendMessage

read_tool = DiscordReadMessages()
send_tool = DiscordSendMessage()

# Example usage:
# response = read_tool({"channel_id": "1234567890", "limit": 5})
# print(response)
#
# send_result = send_tool({"message": "Hello from notebook!", "channel_id": "1234567890"})
# print(send_result)

​
Invocation

​
Direct invocation with args

Below is a simple example of calling the tool with keyword arguments in a dictionary. 
invocation_args = {"channel_id": "1234567890", "limit": 3}
response = read_tool(invocation_args)
response

​
Invocation with ToolCall

If you have a model-generated ToolCall, pass it to tool.invoke() in the format shown below. 
tool_call = {
    "args": {"channel_id": "1234567890", "limit": 2},
    "id": "1",
    "name": read_tool.name,
    "type": "tool_call",
}

tool.invoke(tool_call)

​
Chaining

Below is a more complete example showing how you might integrate the DiscordReadMessages and DiscordSendMessage tools in a chain or agent with an LLM. This example assumes you have a function (like create_react_agent) that sets up a LangChain-style agent capable of calling tools when appropriate. 
# Example: Using Discord Tools in an Agent

from langgraph.prebuilt import create_react_agent
from langchain_discord.tools.discord_read_messages import DiscordReadMessages
from langchain_discord.tools.discord_send_messages import DiscordSendMessage

# 1. Instantiate or configure your language model
# (Replace with your actual LLM, e.g., ChatOpenAI(temperature=0))
llm = ...

# 2. Create instances of the Discord tools
read_tool = DiscordReadMessages()
send_tool = DiscordSendMessage()

# 3. Build an agent that has access to these tools
agent_executor = create_react_agent(llm, [read_tool, send_tool])

# 4. Formulate a user query that may invoke one or both tools
example_query = "Please read the last 5 messages in channel 1234567890"

# 5. Execute the agent in streaming mode (or however your code is structured)
events = agent_executor.stream(
    {"messages": [("user", example_query)]},
    stream_mode="values",
)

# 6. Print out the model's responses (and any tool outputs) as they arrive
for event in events:
    event["messages"][-1].pretty_print()
