Sigil e-signatures

Overview

Sigil e-signatures is a Model Context Protocol server that lets you send PDFs or DOCX files for e-signature as pacts, monitor signer activity, and retrieve completed signed copies. Instead of switching between your AI assistant and a separate e-signature tool, you can work directly through MCP—treating Sigil as a set of callable tools within Claude, Cursor, VS Code, and other supported clients.

This is a remote-hosted server running at https://api.signwithsigil.com/mcp. You authenticate with an API Key and connect immediately—no local installation needed. The latest release is v1.0.7. Full documentation is available at https://docs.signwithsigil.com/mcp.

Sigil e-signatures is listed in the File System category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, you can claim this listing to verify ownership and keep information up to date.
