Connect the Blueink MCP Server

The Blueink MCP server lets AI assistants interact with your Blueink account — search envelopes, check signer status, download documents, and more — all through natural language.

Server URL: https://mcp.blueink.com/mcp

Authentication: Uses the same API key as the Blueink REST API, passed as an Authorization: Token <your_api_key> header.

tip

If you don't have an API key yet, visit the Authentication guide to learn how to obtain one.

Setup by Client

Claude Code

Run this command in your terminal:

claude mcp add --transport http blueink https://mcp.blueink.com/mcp \
  --header "Authorization: Token your_api_key_here"

That's it — the server will be available the next time you start a Claude Code session.

Cursor

1. Open Cursor Settings → MCP.
2. Click Add new MCP server.
3. Choose Type: http (streamable HTTP).
4. Enter the URL: https://mcp.blueink.com/mcp
5. Add the header Authorization: Token your_api_key_here.

Or add it directly to your project's .cursor/mcp.json:

{
  "mcpServers": {
    "blueink": {
      "type": "http",
      "url": "https://mcp.blueink.com/mcp",
      "headers": {
        "Authorization": "Token your_api_key_here"
      }
    }
  }
}

Windsurf

Edit your Windsurf MCP configuration file at ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "blueink": {
      "type": "http",
      "serverUrl": "https://mcp.blueink.com/mcp",
      "headers": {
        "Authorization": "Token your_api_key_here"
      }
    }
  }
}

Restart Windsurf after saving.

VS Code (Copilot)

Add the server to your VS Code settings.json (open via Cmd/Ctrl + Shift + P → Preferences: Open User Settings (JSON)):

{
  "mcp": {
    "servers": {
      "blueink": {
        "type": "http",
        "url": "https://mcp.blueink.com/mcp",
        "headers": {
          "Authorization": "Token your_api_key_here"
        }
      }
    }
  }
}
