E-signature API for AI agents: send contracts, sign PDF documents, track and download signed files.
io.zsign/zsign 是 ChatHome Skills 收录的 MCP 条目，来源为 Official MCP Registry，质量分 93/100。 作为 Model Context Protocol 服务器，它向 Claude、Cursor、Copilot 等兼容 MCP 的 LLM 客户端暴露可直接调用的工具，让 agent 的能力超出模型内置范围。 该条目由 ChatHome Skills 的每日抓取从官方 registry 和 GitHub 发现查询中收录，每次运行都会重新核验仓库事实、新鲜度信号和安装元数据。 质量分综合了官方 registry 收录情况、可用安装命令、许可证完整性、仓库活跃度和 GitHub star 趋势，完整算法说明见来源页。安装命令已列于上方，可直接复制使用。 在将 io.zsign/zsign 加入生产 agent 工作流前，请核对上方的最近更新日期和仓库状态——下方事实快照是最近一次抓取的时点值。
mcp add io.zsign/zsign https://zsign.io/mcp运行此命令前，请先核对上游源码。

As an alternative, set this header to a static 'Bearer zs_live_...' API key. Neither is needed for discovery: create_account and get_pricing work unauthenticated, and create_account returns a key."
