Vendor untestedPython Arrow interfaces for working with record batches and reading or writing IPC streams and files for columnar data exchange.
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.

- 本地库及内存 I/O 不要求厂商账户；文件权限由宿主进程和操作系统决定。远端文件系统或应用自定义 socket 的认证另行处理，本条未覆盖。
- Pricing source
- 本轮已读取官方仓库 main 的 Apache-2.0 主许可及组件来源/附加许可说明；这是源码许可材料，不是服务价格表或全部依赖的完整许可审计。计算、存储、托管及支持费用、实际用户权益继续未知，不承诺整条链路免费。 Pricing source has not been verified.

Limitations and open questions
- 未实测；仅 docs-reviewed，未安装、导入库、打开数据文件或访问远端存储。
- IPC stream 须顺序处理；file reader 要求可 seek；同一 stream 的 record batches 须共享 schema。
- 文档核验不表示已保证跨语言、跨版本或不可信输入的兼容性与安全性。
- 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。
- authentication.required=false 仅描述所选本地库/本地文件工作流没有统一厂商服务账户前提，是有范围的编辑判断；不免除目标网站、远程存储、远程浏览器、操作系统、文件或进程权限。
- 本次不为 Windows/macOS/Linux 兼容矩阵背书；client/server 是库可被集成使用的角色分类。文件系统/应用自定义 socket 的认证和运行资源权限不由 IPC Python 示例决定。
- 代码 LICENSE 链接仍留在 evidence，语义是软件许可材料，不是托管/支持/RPA/运维价目表，也不是相关网页、协议规范或第三方依赖的完整复用授权。
An unlisted MCP, API or CLI means this directory has no reviewed record. It does not establish that the vendor has no such interface.
