Documentation

Signbee MCP Server

Document signing for AI agents — as an MCP tool.

Send, sign, and verify documents with a single tool call. Works with Claude, Cursor, Windsurf, and any MCP-compatible client.

Quick Setup

Claude Desktop

Add to your `claude_desktop_config.json`:

json

{
  "mcpServers": {
    "signbee": {
      "command": "npx",
      "args": ["-y", "signbee-mcp"],
      "env": {
        "SIGNBEE_API_KEY": "your-api-key-from-signb.ee/dashboard"
      }
    }
  }
}

Cursor / Windsurf

Add to your MCP settings:

json

{
  "signbee": {
    "command": "npx",
    "args": ["-y", "signbee-mcp"],
    "env": {
      "SIGNBEE_API_KEY": "your-api-key"
    }
  }
}

> Note: The API key is optional. Without it, the sender verifies via email OTP. With it, documents are sent instantly.

How It Works

1. You ask your AI to send a document for signing

2. The MCP server calls the Signbee API

3. Signbee converts markdown → PDF, handles the signing ceremony

4. Both parties receive a SHA-256 certified signed copy via email

Get Your API Key

1. Go to signb.ee

2. Create an account

3. Navigate to the Dashboard

4. Copy your API key
