Check what this deployment's environment surface supports
Report which environment features this MCPJam deployment accepts. Call it before sending a model override: clients ship independently of the platform, and a field an older deployment does not know is a hard validation error there rather than a silently ignored one. A deployment too old to answer reports false for everything, which is the correct assumption.
Authorizations
MCPJam API key (sk_…). Create one at Settings → API keys. Guest sessions cannot use the API, and API keys cannot manage other API keys.
Path Parameters
ID of the hosted project that contains the server.
Response
The deployment's environment capabilities.
modelId is accepted on environment create and update.
Environment cells may vary by model on one host (the compare grid).
startTestSuiteRun / the v1 group route accept ephemeralEnvironment — a project-scoped env may launch without suite membership. Absent or false on older backends.
