Light tier: a scheduled agent pulls metrics via MCP, drafts a narrative brief — metrics, so-what, anomalies, proposed actions — and posts to Slack or email. This is the cheapest option to build and consistently the highest-read-rate option in client relationships. Start here by default.
Mid tier: Porter Metrics or Looker Studio for visual layout, with a narrative agent generating the interpretation layer on top. For clients who live in spreadsheets, Claude in Excel is a natural mid-tier option that meets them where they work.
Heavy tier: a custom Lovable dashboard over a Supabase database, with scheduled MCP data pulls, an 'ask your data' chat interface powered by Claude API, and your existing read-skills as the tool surface the chat uses to answer questions.
