# Overview

This section collects the AgentScope Java extensions that connect to third-party systems and ecosystem services. Each extension is an independent Maven module under `agentscope-extensions/` — pull in only what you need.

The extensions are grouped by topic:

## Model Providers

All model providers have moved to independent model extension modules, while `agentscope-core` keeps only the shared model contracts. See [Model](/v2/en/docs/building-blocks/model) for the full creation paths, Spring Boot setup, formatters, credentials, and advanced registry behavior.

| Provider  | Maven artifact                          | `ModelRegistry` id            | Standard environment variable                     | Docs                                                                                  |

<Note>
  `agentscope-extensions-model-e2e-tests` is a repository test module, not a user-facing model integration dependency.

## Distributed Storage (Distributed Store)

Full-stack distributed storage components for multi-replica production deployments. Configure agent state, workspace filesystem, sandbox snapshots, and concurrency locks with a single `DistributedStore`.

* [Distributed Storage Overview](/v2/en/integration/distributed/index) — `DistributedStore` API, capability matrix, mixed stores
* [Redis](/v2/en/integration/distributed/redis) — `AgentStateStore` + `BaseStore` + `SandboxSnapshotSpec` + `SandboxExecutionGuard`
* [MySQL / JDBC](/v2/en/integration/distributed/mysql) — `AgentStateStore` + `JdbcStore` + `JdbcSnapshotSpec` + `JdbcSandboxExecutionGuard`
* [Alibaba Cloud OSS](/v2/en/integration/distributed/oss) — `AgentStateStore` + `OssBaseStore` + `OssSnapshotSpec`

## Sandbox Execution Environments

Isolated code execution stores. Docker is built-in; the rest are standalone extension modules.

* Docker — built-in default, no extra dependency
* [Kubernetes](/v2/en/docs/harness/sandbox) — `agentscope-extensions-sandbox-kubernetes`
* [AgentRun (Alibaba Cloud)](/v2/en/docs/harness/sandbox) — `agentscope-extensions-sandbox-agentrun`
* [Daytona](/v2/en/docs/harness/sandbox) — `agentscope-extensions-sandbox-daytona`
* [E2B](/v2/en/docs/harness/sandbox) — `agentscope-extensions-sandbox-e2b`

## Memory

Persist user preferences and facts across sessions. All implementations satisfy the `LongTermMemory` interface.

* [Mem0](/v2/en/integration/memory/mem0)
* [Bailian Memory](/v2/en/integration/memory/bailian)
* [ReMe](/v2/en/integration/memory/reme)

## RAG Knowledge Base

Plug different retrieval stores behind the unified `Knowledge` interface.

* [Simple (DIY embedding + vector store)](/v2/en/integration/rag/simple)
* [Bailian Knowledge](/v2/en/integration/rag/bailian)
* [Dify](/v2/en/integration/rag/dify)
* [HayStack](/v2/en/integration/rag/haystack)
* [RAGFlow](/v2/en/integration/rag/ragflow)

## Skill Repository

Multiple storage implementations of `AgentSkillRepository`.

* [Git Skill Repository](/v2/en/integration/skill/git-repository)
* [MySQL Skill Repository](/v2/en/integration/skill/mysql-repository)
* [PostgreSQL Skill Repository](/v2/en/integration/skill/postgresql-repository)
* See also [Nacos Skill Repository](/v2/en/integration/infrastructure/nacos#skill-repository)

## Channel Adapters

Connect your Agent to messaging platforms through the Harness Channel interface.

* [DingTalk](/v2/en/integration/channel/dingtalk)
* [Feishu / Lark](/v2/en/integration/channel/feishu)
* [GitHub](/v2/en/integration/channel/github)
* [GitLab](/v2/en/integration/channel/gitlab)
* [WeCom](/v2/en/integration/channel/wecom)

## Agent Protocols

Standardized ways for the Agent to talk to the outside world.

* [A2A (Agent-to-Agent)](/v2/en/integration/protocol/a2a)
* [AG-UI](/v2/en/integration/protocol/agui)
* [Agent Protocol](/v2/en/integration/protocol/agent-protocol)

## Infrastructure / Middleware

Plug Agents into your enterprise infrastructure.

* [Higress AI Gateway](/v2/en/integration/infrastructure/higress)
* [Nacos](/v2/en/integration/infrastructure/nacos)
* [Scheduler (Quartz / XXL-Job)](/v2/en/integration/infrastructure/scheduler)

## Ecosystem

Runtime, language, debugging, and training extensions.

* [Chat Completions Web](/v2/en/integration/ecosystem/chat-completions-web)
* [AgentScope Studio](/v2/en/integration/ecosystem/studio)
* [Online Training](/v2/en/integration/ecosystem/training)

<Note>
  For Spring Boot users, most of the above extensions ship a matching `agentscope-spring-boot-starter-*` for one-line integration that removes the manual wiring.
