maivn-studio 0.3.0

Local developer studio for discovering, running, and debugging mAIvn SDK apps

mAIvn Studio

Local developer studio for discovering demos, running sessions, and debugging agent workflows.

Key Capabilities

• Demo discovery from configured repository paths
• Rich demo introspection (agents, swarms, tools, prompts, private data schema)
• Multi-turn session APIs
• Batch Matrix and async-batch session execution with grouped result cards
• Real-time Server-Sent Events stream for execution visibility
• Runtime patching for demos, agents, and swarms

Quick Start

For end users or SDK consumers:

pip install "maivn[studio]"
maivn studio

Run maivn studio from the directory that contains your maivn_studio.json file. Studio discovers that config from the current working directory and then walks up parent directories.

You can also launch the companion package directly:

maivn-studio

For monorepo development:

uv sync
cd apps/maivn-demos
uv run maivn studio

If you need to run the Studio package directly:

cd apps/maivn-studio
uv run -m maivn_studio

If you launch Studio without a config file, the default URL is http://127.0.0.1:8080. The shared demos config at apps/maivn-demos/maivn_studio.json uses http://127.0.0.1:8088.

• ../../libraries/maivn/docs/guides/frontend-events.md

Studio's backend event stream is built on the shared maivn.events.EventBridge contract. Known mAIvn event families are standardized in the shared bridge layer, so Studio inherits canonical packet shapes and stable tool/assignment/scope identities from the SDK. Replay ownership is explicit in the session execution path, Studio keeps any legacy/raw frontend compatibility parsing at the SSE ingress boundary, and the remaining app-specific dedupe is limited to overlapping logical deliveries such as repeated interrupts or repeated identical status messages within a turn.

Configuration

Studio reads maivn_studio.json (if present) for:

• host/port
• demo discovery paths
• explicit demo definitions and variants
