What it does

Share of visitors with prefers-color-scheme: dark vs light. Useful for product decisions ('should we default to dark mode?').

Example prompts

Ask Claude (or any MCP client connected to mcp-analytics) something like:

Dark mode vs light mode on mysite.com — what's the split?

The client will pick color_scheme_breakdown automatically based on the prompt and your account's available sites.

Arguments

Name Type Required Description / Default
site_id string required Site identifier from list_sites (8-character base32, e.g. 'wjxayhdd').
period string optional Time window. Keywords: today, yesterday, last_7_days, last_30_days, last_90_days, last_12_months. Or a custom date range YYYY-MM-DD..YYYY-MM-DD (inclusive).
default: last_7_days

How to call it directly

If you're integrating from your own code rather than a chat client, this is the JSON-RPC payload:

curl -X POST https://mcp-analytics.com/mcp \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "color_scheme_breakdown",
    "arguments": {
      "site_id": "abc12345"
    }
  }
}'

Token comes from /settings after you sign up. Replace any required arguments above.
