CrewAI

Integrate Honcho with CrewAI to build agents that maintain memory across sessions. This guide uses CrewAI’s unified Memory API with Honcho as a custom storage backend.

The full code is available on GitHub with examples in Python.

What We’re Building

CrewAI orchestrates agents, tasks, and memory recall.
Honcho persists CrewAI memory records and exposes additional context, search, and reasoning tools.

CrewAI currently supports Python >=3.10,<3.14; use one of those interpreters when installing this integration.

Setup

Install the packages:

uv add honcho-crewai crewai python-dotenv

pip install honcho-crewai crewai python-dotenv

Set your model provider keys and Honcho configuration:

OPENAI_API_KEY=your_openai_key
HONCHO_API_KEY=your_honcho_key
HONCHO_WORKSPACE_ID=crewai-demo

For local development, initialize the Honcho client with environment="local".

CrewAI Memory Storage

HonchoMemoryStorage implements CrewAI’s current StorageBackend protocol and can be passed directly to Memory(storage=...).

from crewai import Memory
from honcho import Honcho
from honcho_crewai import HonchoMemoryStorage

honcho = Honcho(workspace_id="crewai-demo")
storage = HonchoMemoryStorage(
    peer_id="user-123",
    session_id="session-123",
    honcho_client=honcho,
)
memory = Memory(storage=storage)

CrewAI embeds memory records before storing them. The Honcho backend stores those records as Honcho messages, keeps CrewAI metadata in message metadata, and performs vector search over the stored embeddings.

memory.remember(
    "The user is learning Python and wants to build web applications.",
    scope="/users/user-123",
    categories=["preferences"],
    metadata={"source": "onboarding"},
)

Use the memory instance with a crew:

Python

from crewai import Agent, Crew, Process, Task

agent = Agent(
    role="Programming Mentor",
    goal="Help users learn programming by remembering their interests and progress",
    backstory="You are a patient programming mentor.",
)

task = Task(
    description="Suggest a Python web project that matches the user's interests.",
    expected_output="A specific project suggestion with a brief explanation",
    agent=agent,
)

crew = Crew(
    agents=[agent],
    tasks=[task],
    process=Process.sequential,
    memory=memory,
    verbose=True,
)

result = crew.kickoff()
print(result.raw)

HonchoStorage is still available as a compatibility adapter for older CrewAI ExternalMemory integrations, but new projects should use HonchoMemoryStorage.

CrewAI Tool Integration

Honcho also provides tools that let agents explicitly retrieve memory:

HonchoGetContextTool retrieves session context with token limits.
HonchoDialecticTool queries Honcho’s representation of a peer.
HonchoSearchTool performs semantic search over session messages.

Python

from crewai import Agent, Crew, Process, Task
from honcho import Honcho
from honcho_crewai import (
    HonchoDialecticTool,
    HonchoGetContextTool,
    HonchoSearchTool,
)

honcho = Honcho(workspace_id="crewai-demo")
user_id = "demo-user"
session_id = "tools-demo-session"

user = honcho.peer(user_id)
session = honcho.session(session_id)

for message in [
    "I'm planning a trip to Japan in March",
    "I love authentic local cuisine, especially ramen and sushi",
    "My budget is around $3000 for a 10-day trip",
]:
    session.add_messages([user.message(message)])

context_tool = HonchoGetContextTool(
    honcho=honcho,
    session_id=session_id,
    peer_id=user_id,
)
dialectic_tool = HonchoDialecticTool(
    honcho=honcho,
    session_id=session_id,
    peer_id=user_id,
)
search_tool = HonchoSearchTool(honcho=honcho, session_id=session_id)

travel_agent = Agent(
    role="Travel Planning Specialist",
    goal="Create personalized travel recommendations using memory tools",
    backstory="You are an expert travel planner with access to memory tools.",
    tools=[context_tool, dialectic_tool, search_tool],
    verbose=True,
    allow_delegation=False,
)

task = Task(
    description="Create a personalized 3-day Tokyo itinerary using the memory tools.",
    expected_output="A 3-day Tokyo itinerary with activities, restaurants, and budget notes",
    agent=travel_agent,
)

crew = Crew(
    agents=[travel_agent],
    tasks=[task],
    process=Process.sequential,
    verbose=True,
)

crew.kickoff()

When To Use Each

Use HonchoMemoryStorage when you want CrewAI to handle recall automatically through the unified memory system. Use the Honcho tools when the agent should decide when and how to query memory, search messages, or ask Honcho for a peer-level representation. You can combine both: unified memory for baseline context, tools for targeted retrieval. See the hybrid memory example for a complete implementation.
