Scoped service access for Lovable agents
Lovable can take an application from prompt to a working stack quickly: it may generate a checkout path, provision a Supabase-backed data model, connect GitHub, and prepare a deployment in one build cycle. That speed makes credential design part of the build definition, not a later cleanup. A project that is only prototyping should not inherit a production Stripe key or a Supabase service-role key merely because the generated code needs to test an integration. Keep each app, environment, and integration identity separate; use test-mode billing credentials and project-specific database access while the build is exploratory, then create a deliberately reviewed production path when the application is ready.
Why does Lovable need credential management?
A Lovable build can turn a simple prompt into code that makes outbound API calls, stores configuration, and connects managed services. The hard boundary remains the provider credential: Stripe restricted keys, Supabase project and key type, GitHub repository permissions, and Vercel project controls determine what a delivered secret can do. Gazebo adds a separate decision about whether this particular build may retrieve that prepared credential at all. That distinction matters when several apps are being generated at once: a prototype should not quietly receive credentials intended for another project, and a compromised build or unexpected tool path should be containable without rotating every shared secret.
How Gazebo works with Lovable
- 1
Prepare a project-specific provider credential before connecting it: use Stripe test mode during checkout scaffolding, a Supabase project key appropriate to the task, and a repository-limited GitHub identity rather than an owner credential.
- 2
Create one Lovable profile for a named application and environment. Keep preview, staging, and production profiles separate so a generated preview cannot request production secrets by default.
- 3
Configure the approved credential path through Gazebo's MCP endpoint and keep durable service secrets out of prompts, exported project settings, and generated source files.
- 4
When the build needs a service, it requests the mapped credential at runtime. Gazebo checks the application profile and records the request instead of relying on an ambient environment variable.
- 5
Review the retrieval record with the generated diff, provider logs, and deployment target. Revoke the build profile at handoff or immediately if the requested service, project, or environment changes.
What this looks like in practice
Stripe integration without full billing access
When Lovable scaffolds a Stripe checkout, start with a test-mode credential and restrict the profile to that application. Treat product or price setup, customer data, refund operations, and webhook administration as different risk levels; move to a separately reviewed live credential only after the generated integration, webhook destination, and environment handling have been checked.
Supabase scoped per project
Create a separate Supabase profile for each Lovable project and choose the key type deliberately. Client-facing work should use the project key with tested Row Level Security; a service-role key belongs only in a tightly controlled server-side or migration workflow because it bypasses RLS. A Gazebo profile controls who can retrieve a secret, not the database authority of a broad key after delivery.
Revoke when shipped
Once the application is handed off, revoke the Lovable build profile and preserve the deployment, provider, and credential-retrieval records with the project. The running application should use its own reviewed runtime configuration; the build agent should not retain access simply because the first version shipped successfully.

Environment variables feel like a secure way to pass credentials to AI agents. They're not. Here's why the process environment is a shared bus, not a secrets store — and what to do instead.

What Happens When You Paste an API Key Into an AI Agent's Prompt
It works — that's the problem. When you paste an API key into an agent's prompt, the key enters conversation logs, model context, and provider infrastructure you don't control. Here's where it actually goes.
