Frequently asked questions
What is the difference between Draft and Ongoing status?
A 'draft' request is still being prepared (adding documents or signers). Once you 'activate' it, it becomes 'ongoing' and signers receive their invitations to sign.
How do I download a completed signed document?
When a request status is 'done', you can retrieve download links for each document using the 'get_signature_request' tool through your AI agent.
How does Cline connect to MCP servers?
Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.
Can Cline run MCP tools without approval?
By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.
Does Cline support multiple MCP servers at once?
Yes. Configure as many servers as needed. Cline can use tools from different servers within the same autonomous task execution.
