Environment variables
  • AGENT_COLD_EMAIL_API_KEYsecretBearer token from POST /signup (free, no card) — or run `npx agent-cold-email demo` first. Optional at startup: without it, `initialize`/`tools/list` still work (unauthenticated introspection), but every `tools/call` fails until a key is set.

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.
