把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/io.usefulapi%2Fsignrequest/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。

}Use your SignRequest account from Claude, Cursor, or any MCP client. Read documents, signature requests, templates, teams and events, and send, cancel or resend signature requests. Hosted, no local install: connect with your own credentials.
Live endpoint: https://signrequest.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://signrequest.usefulapi.io/mcp.claude mcp add --transport http signrequest https://signrequest.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your SignRequest credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/signrequest/
On first connect you provide a SignRequest team API token (SignRequest → Team settings → API). The server validates it and stores it per user. No keys go in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with signrequest_upgrade (it returns a Stripe Checkout link). Cancel any time with signrequest_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running signrequest_upgrade before then undoes the cancel. Or write to [email protected].
