Send documents for e-signature, track signers, and organize folders in ZapAssina.
The publisher's own server: Ably MCP by usefulapi
Hosted ZapAssina connector that lets an assistant send documents for e-signature, track signers and deadlines, and organize folders.
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%2Fzapassina/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 ZapAssina account from Claude, Cursor, or any MCP client. Send documents for e-signature, check signers, and organize folders and deadlines. Hosted, no local install: connect with your own credentials.

https://zapassina.usefulapi.io/mcp.claude mcp add --transport http zapassina https://zapassina.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 ZapAssina credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/zapassina/
On first connect you provide a ZapAssina API token (starts with zpa_), created in ZapAssina under Painel → Integrações. The token appears only once. 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.
Each paid plan covers this server only. Ask your AI to run zapassina_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with zapassina_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with zapassina_upgrade before then undoes the cancel. Or write to [email protected].
