From the repository
Install from npm (signbee-mcp) and configure as an MCP tool. Invoke either the send_document tool (with parameters: markdown, sender_name, sender_email, recipient_name, recipient_email, plus optional title and expires_in_days) or the send_document_pdf tool (with parameters: pdf_url, title, sender_name, sender_email, recipient_name, recipient_email, plus optional expires_in_days).
send_document
Send a document for two-party e-signing. Converts markdown to PDF, verifies the sender, emails the recipient a signing link, and delivers a SHA-256 certified signed copy to both parties.
send_document_pdf
Send an existing PDF document for two-party e-signing. Use this when you already have a PDF URL instead of markdown content.
