Product analytics, without the dashboard.

Tellvane is an MCP server for your product's events. Connect it to Claude Code, Codex or Cursor and ask about your users in plain words. Answers come back with real numbers, in the editor you already have open.

Get a key for Claude Code Then this opens Claude Code with the setup typed in.

Run in your terminal.

claude mcp add --transport http tellvane https://api.tellvane.com/mcp \
  --header "Authorization: Bearer wtl_your_key"

Replace wtl_your_key with an agent key from your workspace. Get a key

Then ask

Your agent

how many people signed up this week, and how many came back?

tellvane · events_count signup · last 7 days 412
tellvane · events_retention signup → any event · 3 days 38.1%

412 people signed up this week, 18% more than last week. 157 of them (38%) came back within three days. Tuesday was the peak, the day the launch post went out.

Every number comes from a query against your events. When Tellvane doesn't have the data, it says so instead of guessing.

Send events

One request per event, with an ingest key: it can send events but never read them. Or ask your agent to add the tracking: Tellvane hands it an instrumentation guide for your stack.

Run in your terminal to send a test event.

curl https://api.tellvane.com/v1/events \
  -H "Authorization: Bearer wtl_your_key" \
  -H "Content-Type: application/json" \
  -d '{
    "event": "signup",
    "user_id": "usr_001",
    "properties": { "plan": "free" }
  }'
