Start with your workspace ↗Create in browser →

Hosted assistant

Add the gateway’s MCP address in your client. Sign in and choose the workspace that pays. There’s no local installer.

Local agent

Use the client’s MCP OAuth support, or OpenGen’s source CLI with browser login and a private local profile.

Your application

Create a separate expiring API key in your workspace. Keep its read/generate permissions limited to the job.

Setup guides, with the evidence attached.

Reviewed 2026-11-03. OpenGen’s authorization and CLI have local protocol fixtures. Third-party client versions have not been verified end to end. Hosted sign-in and generation need a configured deployment; a guide is not a claim that the public service is ready.

Local protocol fixtures

What has actually been checked?

Documentation reviewed 2026-11-03. “Protocol fixtures” means synthetic requests against local code, without a real client, identity provider or generation charge.
