Studio
Inspect a developer-owned agent server through a loopback-only local dashboard.
@nylorun/studio serves static UI assets for local inspection. It does not load agent code, proxy
provider requests, or receive browser credentials. Your server remains the owner of agent creation,
model access, storage, authentication, and policy.
npx @nylorun/studio@beta studio --agent-server-url http://127.0.0.1:4111Run Studio and the agent server on the same development machine. Allow Studio's loopback origin in your server's CORS configuration; do not expose a development server or Studio itself as an unauthenticated public service.
Server contract
Studio discovers and inspects agents through these server endpoints:
| Endpoint | Purpose |
|---|---|
GET /v1/agents | Agent IDs and manifest URLs |
GET /agents/:id/manifest.json | One public agent manifest |
POST /agents/:id/v1/ag-ui | AG-UI Server-Sent Events run stream |
GET/POST /agents/:id/v1/sessions/... | Sessions, canonical events, history, and approvals |
The Studio package exports dependency-free discovery and manifest types for implementing this contract. Keep keys, cookies, headers, and raw provider payloads out of Studio configuration, manifests, and events.
Start from the public example
After configuring a provider, run the example's server and Studio together:
npm run build
npm run studioStudio lets you choose an agent, inspect its manifest, run sessions, review approvals, and see the canonical records your server produces. The example is a reference implementation, not a required application framework.
