Create, send and track e-signature documents with their files and recipients in CloudSign.
The publisher's own server: Ably MCP by usefulapi
Hosted CloudSign server that lets an assistant create, send and track e-signature documents, their files and recipients.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fcloudsign/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Use your CloudSign account from Claude, Cursor, or any MCP client. Create, send and track e-signature documents, and read their status and files. Hosted, no local install: connect with your own credentials.

https://cloudsign.usefulapi.io/mcp.claude mcp add --transport http cloudsign https://cloudsign.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 CloudSign credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/cloudsign/
On first connect you provide a CloudSign Web API client ID (CloudSign Web API settings; your team admin issues it). 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 cloudsign_upgrade (it returns a Stripe Checkout link). Cancel any time with cloudsign_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running cloudsign_upgrade before then undoes the cancel. Or write to [email protected].
