BAIQI
Local-first Get the build ↗

Editor automation / MCP server

The control plane between your agent and Unreal.

Baiqi gives AI coding agents a direct, structured way to inspect, build and refine Unreal Engine projects. One local server. Four engine lanes. No Python bridge.

02 / Capability map

From raw scene state
to decisive edits.

Give an agent a clean surface for the work that usually gets lost between a prompt and a viewport.

A / 01

Inspect everything.

Assets, actors, graphs, skeletal data, Niagara stacks and project context are returned as structured JSON, not screenshots alone.

Read the surface ↗
B / 02

Build with intent.

Create editor-native assets and wire real graph relationships with atomic tools an agent can compose.

See the loop ↗
C / 03

Verify in context.

Compile, query, preview and measure the result inside the same editor session before calling the work complete.

Check the build ↗
D / 04

Stay local by default.

Loopback-only transport, session isolation and no cloud dependency keep the project where it belongs: on your machine.

03 / Honest compatibility

One interface.
Version-aware under the hood.

One source tree spans UE 5.5 through 5.8. Where the engine differs, Baiqi says so instead of pretending.

04 / The working loop

Think. Call.
See it land.

Baiqi is not an autonomous black box. It is the reliable set of hands an agent needs inside the editor.

  1. 01
    Read the scene

    Pull only the context needed for the next decision.

  2. 02
    Make one atomic edit

    Create, connect, compile or transform without hidden heuristics.

  3. 03
    Close the loop

    Read back the result and continue until the scene is right.

05 / Current release

Ship a smarter
editor workflow.

Start with the Win64 build for your Unreal version. No database, account or remote control plane required.
