Signbee MCP Server enables AI agents to send documents for legally-binding two-party e-signing from MCP-compatible clients like Claude Desktop, Cursor, and Windsurf.
Send a markdown document for e-signing (
send_document): Provide markdown content with sender/recipient details; Signbee auto-converts it to a professional PDF and initiates the signing workflow. The document title can be auto-extracted from the first heading if not provided.Send an existing PDF for e-signing (
send_document_pdf): Provide a publicly accessible PDF URL along with sender/recipient details to initiate signing.Automated signing ceremony: Handles the full flow — emailing the recipient a signing link and delivering a SHA-256 certified signed copy to both parties upon completion.
Configurable expiry: Set signing link validity from 1–30 days (default: 7).
Optional API key authentication: Without an API key, the sender verifies via email OTP; with one, documents are sent instantly.
Enables the conversion of Markdown document content into professional, SHA-256 certified PDFs for two-party e-signing, including automatic document title extraction from Markdown headings.
