Setup:

  1. Sign in to https://app.hellosign.com → top-right avatar → API → Test Mode + Live API → Generate API Key.
  2. Use the test API key during development; switch to live when going to production.
  3. Set DROPBOX_SIGN_API_KEY.

Authentication: HTTP Basic with username=API_KEY, password=empty.

test_mode: every write endpoint accepts test_mode=1 to NOT charge credits / NOT send real signature requests. Always test first.

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d
