eSign Launchpad MCP Server

MCP (Model Context Protocol) server that enables AI agents to interact with the eSign Launchpad e-signature platform. Create, send, and manage signing packages directly from Claude, Cursor, or any MCP-compatible AI client.

Quick Start

# Install
npm install @esignlaunchpad/mcp-server

# Run (requires API key)
ESIGN_API_KEY=eslp_live_your_key_here npx @esignlaunchpad/mcp-server

Claude Desktop Configuration

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "esign-launchpad": {
      "command": "npx",
      "args": ["@esignlaunchpad/mcp-server"],
      "env": {
        "ESIGN_API_KEY": "eslp_live_your_key_here"
      }
    }
  }
}

What Can AI Agents Do?

With this MCP server, AI agents can:

• Create signing packages with documents, signers, and annotation fields
• Upload documents (PDF, DOCX) via chunked upload
• Add signers with authentication requirements (email, SMS, KBA, ID verification)
• Place signature fields on documents with precise positioning
• Send packages for signing with custom email messages
• Track status of packages and individual signers
• Download completed documents and certificates of completion
• Manage templates for reusable signing workflows
• Configure webhooks for real-time event notifications
• Manage signing groups for team-based signing

How It Works

This MCP server reads the eSign Launchpad OpenAPI specification at startup and dynamically generates MCP tools for each API endpoint. When the API is updated with new features, simply restart the server to pick up new tools automatically.

No code generation needed. No manual tool definitions. The OpenAPI spec is the single source of truth.
