Environment variables
  • PROOF_API_KEYsecretProof Holdings API key (Bearer). Optional: without it the server runs in public mode, where account creation, login and public verification tools work and every other tool asks for a key. Create one in the dashboard at https://proof.holdings. Or run `npx @proof-holdings/mcp-server login` in a terminal: it signs in, confirms on a second channel and saves a key in ~/.proof-holdings/credentials, which the server uses when this variable is unset (this variable wins when set). Either is read at startup and has no runtime setter, so restart the server after logging in.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
