What each one is

GrowthBook. The warehouse-native platform used by modern product teams for experimentation, feature flags, and product analytics.

Mixpanel. Product intelligence platform for the AI era that helps teams understand customers and make data-driven decisions.

Where GrowthBook is ahead

GrowthBook passes structured api reference and authentication documented, and Mixpanel does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

It also holds adopt: fast time to first request and copyable quickstart. Mixpanel misses those.

And on operate, agent compatibility verified. Mixpanel misses it.

Where Mixpanel is ahead

Mixpanel passes clear product positioning, and GrowthBook does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: agent-compatible signup flow. GrowthBook misses it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.
