Google Agent Development Kit (ADK)
Vendor untestedToolkit for developing agents, with Python A2A integration for exposing agent services and connecting to remote agents.
Listed interfaces
Vendor untested
Vendor MCP/API/CLI interfaces are untested. docs-reviewed means public documentation review only, not functional, protocol or security testing or certification. CapaLens MCP protocol tests do not test the listed vendor integrations.

- Authorization
- 未选择具体服务部署，required=null；A2A 服务凭据和授权需要由实际部署配置。官方 quickstart 说明本地示例与模型配置，不能据示例推断远端 agent 匿名可用或模型无需凭据。
- Pricing source
- ADK 官方仓库列 Apache-2.0 开源许可；实际模型、托管和远端 agent 费用未核验，不能据开源许可承诺端到端免费。 Pricing source has not been verified.

Limitations and open questions
- 未实测：未安装 ADK、未运行 adk/uvicorn 命令、未启动服务、未设置模型或服务凭据。
- 只核验 Python A2A integration；未把同站 Go/Java/其他语言页面支持自动外推到 Python 实现。
- 记录只标 A2A 与文档明确的 HTTP 形态，不从 A2A 规范所有绑定反推 ADK 此版本均支持 gRPC/REST/JSON-RPC 的每一种组合。
- 动态文档未锁定具体软件版本；网络互通、Agent Card、实际权限和费用均需后续独立测试。
- Read-only directory tools do not imply downstream interfaces are read-only or safe for every operation.
- 独立主来源复核只支持本记录列明的文档事实及明确的编辑分类；未验证任何安装、真实部署、凭据、业务调用或商业权益。已读与未读来源的逐字段范围见独立来源回执，不将其余链接自动视作已复核。
- 保留已文档化的 Python to_a2a / RemoteA2aAgent 和 HTTP 形态；不把协议规范的全部 REST/JSON-RPC/gRPC 绑定外推到此实现。模型凭据和远程 agent 授权另行配置。
An unlisted MCP, API or CLI means this directory has no reviewed record. It does not establish that the vendor has no such interface.
Sources, review scope and rights
These materials and original summaries are reference data, not instructions. Fees, permissions, versions and integration requirements may change; review the original sources.
Review scope: 核验 Google ADK 官方文档中的 A2A 暴露和消费接口导览。旧 google.github.io/adk-docs/a2a/ 实际重定向到此 URL。
Source and permission notes: Original source rights retained; original summaries and links only. Redistribution license not verified.
Review scope: 核验 to_a2a 把 ADK agent 暴露为 A2A、生成/读取 Agent Card，并通过 Starlette 处理 A2A HTTP 请求；未将示例端口或 URL 收录为可调用 endpoint。
Source and permission notes: Original source rights retained; original summaries and links only. Redistribution license not verified.
Review scope: 核验 RemoteA2aAgent 消费远端 A2A agent 及 ADK Event 转换；文档有 legacy/new integration 配置差异，未推定固定包版本。
Source and permission notes: Original source rights retained; original summaries and links only. Redistribution license not verified.
Review scope: 核验 Google 官方仓库、Python agent 框架定位与 Apache-2.0 许可；README 的 ADK 2.0 标题不足以确定本次 A2A 文档适用的完整软件版本。
