mcp-server-esignatures
The most developer- and AI-friendly electronic signature platform.
Traditional eSignature tools lock you into rigid, static PDF files. eSignatures.com takes a different approach — contracts remain fully editable, Markdown-based content throughout their entire lifecycle, making them effortless for developers, automation systems, and AI agents to create, understand, modify, and manage.
This MCP server gives AI agents (such as Claude) real-time access to the complete eSignatures API, enabling:
- Dynamic contract creation and editing — even after sending
- Markdown-based content that AI can generate, understand, and update
- End-to-end workflows: drafting → placeholder filling → sending → signing → amendments
- Flexible templates and reusable contract workflows
- Signer management, notifications, and lifecycle automation
Built for intelligent, adaptive contract workflows — not outdated PDF-based signing.
