ZepTools enable an Agent to interact with a Zep memory system, providing capabilities to store, retrieve, and search memory data associated with user sessions.

​
Prerequisites

The ZepTools require the zep-cloud Python package and a Zep API key. 
pip install zep-cloud

export ZEP_API_KEY=your_api_key

​
Example

The following example demonstrates how to create an agent with access to Zep memory:
cookbook/tools/zep_tools.py
import time

from agno.agent import Agent
from agno.models.openai import OpenAIChat
from agno.tools.zep import ZepTools

# Initialize the ZepTools
zep_tools = ZepTools(user_id="agno", session_id="agno-session", add_instructions=True)

# Initialize the Agent
agent = Agent(
    model=OpenAIChat(),
    tools=[zep_tools],
    dependencies={"memory": zep_tools.get_zep_memory(memory_type="context")},
    add_dependencies_to_context=True,
)

# Interact with the Agent so that it can learn about the user
agent.print_response("My name is John Billings")
agent.print_response("I live in NYC")
agent.print_response("I'm going to a concert tomorrow")

# Allow the memories to sync with Zep database
time.sleep(10)

# Refresh the context
agent.context["memory"] = zep_tools.get_zep_memory(memory_type="context")

# Ask the Agent about the user
agent.print_response("What do you know about me?")

Toolkit Params

ParameterTypeDefaultDescription
session_idstrNoneOptional session ID. Auto-generated if not provided.
user_idstrNoneOptional user ID. Auto-generated if not provided.
api_keystrNoneZep API key. If not provided, uses ZEP_API_KEY env var.
ignore_assistant_messagesboolFalseWhether to ignore assistant messages when adding to memory.
enable_add_zep_messageboolTrueAdd a message to the current Zep session memory.
enable_get_zep_memoryboolTrueRetrieve memory for the current Zep session.
enable_search_zep_memoryboolTrueSearch the Zep memory store for relevant information.
instructionsstrNoneCustom instructions for using the Zep tools.
add_instructionsboolFalseWhether to add default instructions.

​
Toolkit Functions

FunctionDescription
add_zep_messageAdds a message to the current Zep session memory. Takes role (str) for the message sender and content (str) for the message text. Returns a confirmation or error message.
get_zep_memoryRetrieves memory for the current Zep session. Takes optional memory_type (str) parameter with options “context” (default), “summary”, or “messages”. Returns the requested memory content or an error.
search_zep_memorySearches the Zep memory store for relevant information. Takes query (str) to find relevant facts and optional search_scope (str) parameter with options “messages” (default) or “summary”. Returns search results or an error message.

​
Async Toolkit

The ZepAsyncTools class extends the ZepTools class and provides asynchronous versions of the toolkit functions.
