Broad access
Why this level
- The agent runs arbitrary scripts inside working applications and can change or delete open projects.
Install
- Works in

What it does
Flue installs a bridge between an agent and desktop software. The agent sends a script through a small command, the bridge runs it inside the application's own automation runtime and the app returns JSON. The path is agent shell, bridge command, app scripting runtime, result. The bundle has adapters for Photoshop, Illustrator, InDesign, Premiere Pro, After Effects, Audition, Blender, Unity, Houdini, 3ds Max, Word, Excel, PowerPoint and Figma (desktop app with a one-time plugin import). `flue setup` finds installed agent harnesses and tells them Flue is available. Servers, schemas and screenshots are unnecessary because the bridge takes the scripting layer the program already has. Each adapter ships its own `APP.md` and `AGENTS.md`.
Who it is for. Designers, 3D artists and game developers who hand routine work in Adobe, Blender or Unity to an agent.
Good fit when
- Objects in Blender need to be placed from a description and checked by the agent.
- Layers in Photoshop or Illustrator need a batch fix by script.
- An Excel or Word document should be built from a brief, not by hand.
- A Unity or Houdini scene needs to be inspected and changed from the command line.
Not a fit when
- The program has no scripting interface.
- A ready MCP server for the app is enough.
- The environment forbids the agent from running scripts in production applications.
Example request
Open the project in Blender, add a blue cube to the scene and return the object list with coordinates.Limitations
The bridge runs agent code inside the program, so the agent can change or break an open project: keep a copy of the file before a session. Some programs need extra setup, for example a plugin import for Figma; details are in each adapter's `APP.md`. Support depends on the platform: the README lists Windows and macOS. The project is young and describes itself as a general framework, so the known-issues page in the docs is useful for rare operations.
How to disable. Remove the package with `pip uninstall flue` and delete the files `flue setup` added to the agent configurations (the list is in `docs/harnesses.md`).
FAQ
How do I install it?
Run `pip install flue`, then `flue setup`. The second command finds agent harnesses and wires up the bridge.
Which agents are supported?
Claude Code, Codex, Copilot, Cursor, OpenCode, OpenClaw, Hermes, Gemini CLI, Antigravity CLI, Qwen CLI, Cline and Kilo CLI. The files edited during install are listed in `docs/harnesses.md`.
How is this different from MCP?
Instead of a server with tool schemas, the agent sends a script to the application's native runtime. The comparison is in `docs/mcp.md`.
What does the bridge return?
JSON with the result of the script run inside the application.
Do individual apps need setup?
Sometimes. Agents are meant to tell the human, and the steps are in each adapter's `APP.md`.

README in short
One install command sets up a bridge for many programs. The agent talks to the application with scripts through the shell and receives JSON.
