Version 1.0.0. Source 8fa19125.

Independent security review is incomplete. Read the publication exception.

One prompt. A connected creative workflow.

Watch Semwright update an aircraft’s materials in Blender, render a new camera shot, generate branded titles in Motion Canvas, and assemble the video with audio through MLT—all using Semwright’s drivers.

Recorded in one take using an existing aircraft project. Waiting periods are accelerated; the final playback runs at normal speed. The workflow produces a new video and an editable timeline.

Watch the 60-second demo.

Software has structure.
Agents should use it.

Work with a document’s nodes, a scene’s objects or a timeline’s clips. Semwright turns application meaning into an inspectable contract.

Semantic objects

Named objects and typed capabilities, exposed through application interfaces.

Policy boundaries

Authority evaluated before execution, with explicit scope and limits.

Refs and jobs

Object identity and ongoing work with lifetimes you can inspect.

Observable results

Read back state, evaluate effects and keep the execution evidence.

A clear path from
intent to action.

Each boundary has a job. Each operation leaves something you can inspect.

AgentTyped intent

A named operation with explicit inputs.

Readback and audit

Authority before action. Discovery does not grant execution. Policy evaluates the requested operation and its scope.

Identity with a lifetime. References address objects within a session. Stale or invalid references must be resolved again.

Work you can inspect. Session-bound jobs expose progress and results, with cooperative cancellation where supported.

Semwright RequestRequest illustration

Ask for the thing you mean.

The agent calls a typed operation instead of guessing a screen coordinate.

Operation: ui.find
Application: Text Editor
Looking for: Save button

Get a semantic reference back.

Semwright identifies the object and reports the actions that object exposes.

Matched objectSaveui:window/toolbar/saverole: button / action: click

Permission stays in the path.

The request can only dispatch when the current reference and required authority are both valid.

Operation: ui.invoke
Action: click
Dispatch: Text Editor provider

No pixel guessing.Shared execution path

Your agent gets access.
You keep the keys.

Discovering a capability does not grant authority to run it. Input, capture and application changes pass through explicit policy.

Semwright ControlPolicy illustration

Choose what an agent may do.

Discovery can stay broad while sensitive actions remain separately controlled.

App changesNative write or destructive operationsPolicy checked

Point to meaning, not pixels.

Semwright returns semantic references that identify the object an agent actually found.

Application: org.gnome.TextEditor
Object: Save
Role: button
Reference: ui:window/toolbar/save

If a reference is stale or ambiguous, the request stops instead of guessing.

Is Semwright another AI agent?

No. Semwright is the interface an agent calls, not the model that decides what to do. It exposes capabilities and mediates execution. You bring the agent.

Why not just give an agent a shell?

A shell usually inherits broad user authority. Semwright is built around narrower operations, scoped references, explicit permissions and one audit path.

Is this only an MCP server?

MCP is one frontend. The CLI, inspector and recipes use the same broker. Application drivers and federated MCP providers extend the capability catalogue.

What can I use today?

Semwright 1.0.0 native bundles include the CLI, daemon, MCP frontend and inspector. Install, run semwright setup and connect your client. Application coverage stays version-specific; read the compatibility guide for the evidence and limits.

What does cross-platform mean today?

Native bundles are available for Linux, macOS and Windows on x64 and ARM64. Packaging tests and portable SDK tests are distinct from physical desktop acceptance. Read the compatibility guide for the environment-specific limits and incomplete security-review status.
