LLM Goal classifications

Optional intelligence layer for Pay-as-you-go. Uses an LLM to classify each session against your custom goals — bug-hunt, schema discovery, retrieval, etc. — so you can see what your users are actually accomplishing.

LLM Goals
Add-on · pairs with Pay-as-you-go

Define what success looks like for your MCP server in plain English. We'll classify every session — completed, abandoned, partial — and surface the "why" behind your usage curves. Especially useful for agentic flows where a single intent spans many tool calls.

  • Define goals in natural language
    No taxonomy or schema work — write what success looks like.
  • Per-session classification
    Every session tagged against your goal set, with confidence scores.
  • Funnel + drop-off analytics
    See where users abandon and which tools correlate with success.
