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 for the full creation paths, Spring Boot setup, formatters, credentials, and advanced registry behavior.
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 — DistributedStore API, capability matrix, mixed stores
  • Redis — AgentStateStore + BaseStore + SandboxSnapshotSpec + SandboxExecutionGuard
  • MySQL / JDBC — AgentStateStore + JdbcStore + JdbcSnapshotSpec + JdbcSandboxExecutionGuard
  • Alibaba Cloud 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 — agentscope-extensions-sandbox-kubernetes
  • AgentRun (Alibaba Cloud) — agentscope-extensions-sandbox-agentrun
  • Daytona — agentscope-extensions-sandbox-daytona
  • E2B — agentscope-extensions-sandbox-e2b

​
Memory

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

​
RAG Knowledge Base

Plug different retrieval stores behind the unified Knowledge interface.

​
Skill Repository

Multiple storage implementations of AgentSkillRepository.

​
Channel Adapters

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

​
Agent Protocols

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

​
Infrastructure / Middleware

Plug Agents into your enterprise infrastructure.

​
Ecosystem

Runtime, language, debugging, and training extensions.
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.
