adk-redis is the Redis layer for Google ADK agents. It implements ADK's BaseMemoryService, BaseSessionService, and BaseTool interfaces against Redis, Redis Vector Library, Redis Agent Memory. It also ships MCP toolset helpers and semantic-cache providers.

Installation

pip install adk-redis

Optional extras:

pip install 'adk-redis[memory]'      # sessions + long-term memory services
pip install 'adk-redis[search]'      # RedisVL-backed search tools
pip install 'adk-redis[sql]'         # RedisSQLSearchTool
pip install 'adk-redis[langcache]'   # managed semantic cache provider
pip install 'adk-redis[all]'         # everything above

Memory backends are selected with backend:

The memory extra installs redis-agent-memory>=0.2.0 for the managed backend.

Quick start

Prerequisites: Python 3.10+, Redis 8.4+, and one memory backend. See the Quickstart for full setup steps.

from google.adk import Agent
from google.adk.runners import Runner

from adk_redis import (
    RedisLongTermMemoryService,
    RedisLongTermMemoryServiceConfig,
    RedisSessionMemoryService,
    RedisSessionMemoryServiceConfig,
)

session_service = RedisSessionMemoryService(
    config=RedisSessionMemoryServiceConfig(
        backend="redis-agent-memory",
        api_base_url="http://localhost:8088",
        api_key="...",
        store_id="...",
        default_namespace="my_app",
    ),
)
memory_service = RedisLongTermMemoryService(
    config=RedisLongTermMemoryServiceConfig(
        backend="redis-agent-memory",
        api_base_url="http://localhost:8088",
        api_key="...",
        store_id="...",
        default_namespace="my_app",
    ),
)

agent = Agent(
    model="gemini-2.5-flash",
    name="memory_agent",
    instruction="You are a helpful assistant with long-term memory.",
)

runner = Runner(
    app_name="my_app",
    agent=agent,
    session_service=session_service,
    memory_service=memory_service,
)

For the open source self-hosted Agent Memory Server, set backend="opensource-agent-memory" and omit api_key and store_id unless your server requires them.

Examples

Each example ships with a README and .env.example. Memory and session examples that register services through get_service_registry() run via python main.py; tools-only and search examples run via adk web. See each example's README and the Examples index for the runner and backend each uses.

Development

git clone https://github.com/redis-developer/adk-redis.git
cd adk-redis
make dev               # install with all extras + dev deps
make check             # format, lint, type-check, and test
