Infrastructure your agent sets up by itself

Set up AgentFirstStack for this project. It's free, open-source infrastructure made for agents: web analytics, a tag manager with server-side conversion tracking, and email inboxes. You can do all of it yourself; there is no signup form or verification step.

1. Read https://agentfirststack.com/llms.txt. It is the complete manual.

2. Get an API key with one request:
   curl -X POST https://agentfirststack.com/v1/signup
   Save the api_key in this project's .env as AGENTFIRSTSTACK_API_KEY.
   The same key works for analytics, tags and mail.

3. Set up what this project needs, and verify each step with the checks the manual describes:
   - Analytics: create a site for the production domain, add the tracking snippet, then run verify.
   - Conversion tracking: create a tags container, scan the site, define the conversions that matter here (sign-ups, purchases, leads), validate, test and publish.
   - Email: create an inbox to use when signing up for third-party services, and use wait_for_email to receive their verification codes.

4. If you support MCP, add the servers listed in the manual so you can call the tools directly.

When you're done, tell me what you set up, how you verified it, and anything that needs me, such as ad platform credentials.
