cognee-integration-google-adk 0.1.1

Integrate Cognee's memory system seamlessly with your Google ADK agent using easy-to-use tools.

Cognee-Integration-Google-ADK

A powerful integration between Cognee and Google ADK that provides intelligent memory management and retrieval capabilities for AI agents.

Overview

cognee-integration-google-adk combines Cognee's advanced memory layer with Google's Agent Development Kit (ADK). This integration allows you to build AI agents that can efficiently store, search, and retrieve information from a persistent knowledge base.

Features

• Smart Knowledge Storage: Add and persist information using Cognee's advanced indexing
• Semantic Search: Retrieve relevant information using natural language queries
• Session Management: Support for user-specific data isolation
• Google ADK Integration: Seamless integration with Google's Agent Development Kit
• Async Support: Built with async/await for high-performance applications
• Long-Running Tools: Optimized for Google ADK's long-running tool capabilities
• Thread-Safe: Queue-based processing for concurrent operations

Installation

pip install cognee-integration-google-adk

Quick Start

import asyncio
from dotenv import load_dotenv
import cognee
from google.adk.agents import Agent
from google.adk.runners import InMemoryRunner
from cognee_integration_google_adk import add_tool, search_tool

load_dotenv()

async def main():
    # Initialize Cognee (optional - for data management)
    await cognee.prune.prune_data()
    await cognee.prune.prune_system(metadata=True)
    
    # Create an agent with memory capabilities
    agent = Agent(
        model="gemini-2.0-flash",
        name="research_analyst",
        description="You are an expert research analyst with access to a comprehensive knowledge base.",
        instruction="You are an expert research analyst with access to a comprehensive knowledge base.",
        tools=[add_tool, search_tool],
    )
    
    runner = InMemoryRunner(agent=agent)
    
    # Use the agent to store information
    events = await runner.run_debug(
        "Remember that our company signed a contract with HealthBridge Systems "
        "in the healthcare industry, starting Feb 2023, ending Jan 2026, worth £2.4M"
    )
    
    # Print agent response
    for event in events:
        if event.is_final_response() and event.content:
            for part in event.content.parts:
                if part.text:
                    print(part.text)
    
    # Query the stored information
    events = await runner.run_debug(
        "What contracts do we have in the healthcare industry?"
    )
    
    for event in events:
        if event.is_final_response() and event.content:
            for part in event.content.parts:
                if part.text:

    asyncio.run(main())

Available Tools

Basic Tools

from cognee_integration_google_adk import add_tool, search_tool

# add_tool: Store information in the knowledge base
# search_tool: Search and retrieve previously stored information

Sessionized Tools

For multi-user applications, use sessionized tools to isolate data between users:

from cognee_integration_google_adk import get_sessionized_cognee_tools

# Get tools for a specific user session
add_tool, search_tool = get_sessionized_cognee_tools("user-123")

# Auto-generate a session ID
add_tool, search_tool = get_sessionized_cognee_tools()

Session Management

cognee-integration-google-adk supports user-specific sessions to tag data and isolate retrieval between different users or contexts:

import asyncio
from google.adk.agents import Agent
from google.adk.runners import InMemoryRunner
from cognee_integration_google_adk import get_sessionized_cognee_tools

async def main():
    # Each user gets their own isolated session
    user1_add, user1_search = get_sessionized_cognee_tools("user-123")
    user2_add, user2_search = get_sessionized_cognee_tools("user-456")
    
    # Create separate agents for each user
    agent1 = Agent(
        model="gemini-2.0-flash",
        name="assistant_1",
        description="Assistant for user 1",
        instruction="You are a helpful assistant.",
        tools=[user1_add, user1_search]
    )
    
    agent2 = Agent(
        model="gemini-2.0-flash",
        name="assistant_2",
        description="Assistant for user 2",
        instruction="You are a helpful assistant.",
        tools=[user2_add, user2_search]
    )
    
    runner1 = InMemoryRunner(agent=agent1)
    runner2 = InMemoryRunner(agent=agent2)
    
    # Each agent works with isolated data
    await runner1.run_debug("Remember: I like pizza")
    await runner2.run_debug("Remember: I like sushi")

if __name__ == "__main__":
    asyncio.run(main())

Advanced Usage

Pre-loading Data

You can pre-load data into Cognee before creating agents:

import asyncio
import cognee
from cognee_integration_google_adk import search_tool
from google.adk.agents import Agent
from google.adk.runners import InMemoryRunner

async def main():
    # Pre-load data
    await cognee.add("Important company information here...")
    await cognee.add("More data to remember...")
    await cognee.cognify()  # Process and index the data
    
    # Now create an agent that can search this data
    agent = Agent(
        model="gemini-2.0-flash",
        name="analyst",
        description="Analyst with access to company knowledge base",
        instruction="You have access to our company knowledge base.",
        tools=[search_tool]
    )
    
    runner = InMemoryRunner(agent=agent)
    events = await runner.run_debug("What information do we have?")
    
    for event in events:
        if event.is_final_response() and event.content:
            for part in event.content.parts:
                if part.text:
                    print(part.text)

if __name__ == "__main__":
    asyncio.run(main())

Data Management

import asyncio
import cognee

async def reset_knowledge_base():
    """Clear all data and reset the knowledge base"""
    await cognee.prune.prune_data()
    await cognee.prune.prune_system(metadata=True)

    data_runner = InMemoryRunner(agent=data_agent)
    research_runner = InMemoryRunner(agent=research_agent)

    await data_runner.run_debug(
        "Store this: Project Alpha launched in Q1 2024 with $5M budget"
    )
    
    # Search data
    events = await research_runner.run_debug(
