Zep

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 following example requires the zep-cloud and openai Python packages and a Zep API key.

uv pip install zep-cloud openai

export ZEP_API_KEY=your_api_key

Example

The following example demonstrates how to create an agent with access to Zep memory:

cookbook/91_tools/zep_tools.py

import time

from agno.agent import Agent
from agno.models.openai import OpenAIResponses
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=OpenAIResponses(id="gpt-5.2"),
    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.dependencies["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

Parameter	Type	Default	Description
`session_id`	`str`	`None`	Optional session ID. Auto-generated if not provided.
`user_id`	`str`	`None`	Optional user ID. Auto-generated if not provided.
`api_key`	`str`	`None`	Zep API key. If not provided, uses ZEP_API_KEY env var.
`ignore_assistant_messages`	`bool`	`False`	Whether to ignore assistant messages when adding to memory.
`enable_add_zep_message`	`bool`	`True`	Enables the `add_zep_message` tool.
`enable_get_zep_memory`	`bool`	`True`	Enables the `get_zep_memory` tool.
`enable_search_zep_memory`	`bool`	`True`	Enables the `search_zep_memory` tool.
`instructions`	`str`	`None`	Custom instructions for using the Zep tools.
`add_instructions`	`bool`	`False`	Whether to add default instructions.
`all`	`bool`	`False`	Enables all tools when set to True.

Toolkit Functions

Function	Description
`add_zep_message`	Adds 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_memory`	Retrieves memory for the current Zep session. Takes optional `memory_type` (str) parameter with options “context” (default) or “messages”. Returns the requested memory content or an error.
`search_zep_memory`	Searches the Zep knowledge graph for relevant facts or nodes. Takes `query` (str) to find relevant results and optional `search_scope` (str) parameter with options “edges” (default, for facts) or “nodes”. Returns search results or an error message.

Async Toolkit

The ZepAsyncTools class provides asynchronous versions of the toolkit functions.
