A2A Python SDK
Vendor untestedPython SDK for building A2A clients and servers, with separate protocol bindings for communication between agent services.
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
- 具体部署的 Agent Card 与服务端策略决定凭据和授权；未指定或连接实例，故 required=null。A2A 官方规范要求在 HTTP 层声明/传递认证并由服务端授权，凭据取得在协议之外。没有收录或配置真实凭据。
- Pricing source
- 官方仓库列 Apache-2.0 开源许可；SDK 许可不代表部署、模型或远端 agent 免费，本次未核验这些价格。 Pricing source has not been verified.

Limitations and open questions
- 未实测：未安装 SDK、未启动 server/client、未使用 inspector、未调用任何 agent 或模型。
- 这是可构建 agent 服务的开源实现，不是公共托管 agent endpoint；未生成或猜测可调用地址。
- 绑定支持依赖选装组件和对应配置；规范兼容声明不等于所有特性/版本/对等实现均已互通。
- 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。
- 官方实现表的协议 1.0 / 兼容 0.3 是协议兼容声明，不是 SDK 软件版本或已互通结果；当前 gRPC 序列化格式未独立细读，绑定 dataFormats 留空，不从其他 JSON binding 补齐。
An unlisted MCP, API or CLI means this directory has no reviewed record. It does not establish that the vendor has no such interface.

Review scope: 核验官方 SDK 身份、Python 3.10+、异步 client/server、JSON-RPC/HTTP+JSON REST/gRPC 绑定及 Apache-2.0 许可。README 声明 A2A spec 1.0 与 0.3 compatibility；本次未锁定完整 SDK 发布版本。

Review scope: 核验 a2a-sdk 的 client、server、auth 与 grpc/jsonrpc/rest transport 模块文档；这仅证明文档列有这些模块，非互通测试。

Review scope: 共享协议层证据：生产 HTTPS、Agent Card 认证声明、HTTP 头携带凭据与服务端授权；不是某个部署已实施这些控制的证据。

Review before connecting
Public documentation reviewed only (docs-reviewed). Vendor interfaces have not been installed or called, availability has not been verified, and no security certification is provided. Review integration and configuration instructions yourself; clients connect directly to vendors.
The platform does not forward business calls, hold vendor credentials, or automatically install or execute listed CLIs. Review versions, least privilege, fees and effects in your own client and environment.
