# Test mode

> Free playground and kp_test_ keys — cannot call production

Test mode is how you evaluate RCIntel without a paid plan.

## What you get for free

* [Playground](https://rcintell.com/playground) — signed-in, server-side proxy, no key in the browser
* `kp_test_` keys from [sign up](https://rcintell.com/signup)
* Mock CCNs and sample CPT codes
* Hosted MCP on `https://api-dev.rcintell.com/v1/mcp`

## What you cannot do with a test key

* Call `https://api.rcintell.com` (production)
* Exceed the free daily / monthly quota
* Hit mutating or agent-compute routes outside the trial allowlist

## Mock CCNs
